Foreword

Foreword

There are many ways to model custom parts in Tekla Structures. In many cases custom partsare used hundreds or even thousands of times in a single model. Consequently, it is crucial tohave an awareness of how to properly setup custom parts in your model. The method usedwill have a significant impact on the model, drawings, and reports.

It is not recommended that precast elements be model as custom parts. This will addcomplexity to a model and possibly lead to undesired results in the drawings and reports. Oneexception is a sandwich panel which would be difficult to manage without the use of customparts. The assembly functionality should be managed using components, not in the model.It is very important to use custom parts and to use the custom components in your modeling

practice. This document is designed to recommend a path that will lead to optimalproductivity and performance.

BackgroundCustom parts are setup and intended to be small arrangements of parts that represent one unit.Custom components allow the storage and use of this unit as if it were once piece, but inpractice it could be a dozen or so individual pieces kept together. The most common casewould be an embed. Custom parts are stored in the component library for efficient use.The information concerning these custom parts is handled in a unique way by the system.There is one library copy in the component catalog but it is used many times in the model.Anytime the user needs to change this custom part they can edit the component cataloginstance and the system will update every use of this Custom Part in the model.

General RecommendationsLoose parts are handled differently in the model than custom parts and they should be avoidedwhen possible. Custom parts are designed to be used and inserted in the model using othercustom components such as a custom details, custom connections, or custom seams. You can

loosely put custom parts in the model but this is not recommended.By using custom components to insert custom parts into the model, tasks are automatedand detailing is kept consistent leading to much better results and productivity. It is veryimportant for custom components to be used and for assigning parts to cast units so it isalways kept with model changes. Using custom components has a huge impact on modelingconsistency and will lead to fewer detailing errors later on. Remember that you should usenumbering on a regular basis to check and fix your work as you go.

Defining Assembly Hierarchy

Defining Assembly HierarchyHaving a custom part does not guarantee that it is correctly defined as an assembly. To ensurethat it is a proper assembly, the assembly of a custom part should always be checked insideedit mode or as it is being created. Assemblies of more than one part should be handled byusing welds. Custom parts should be divided up you so that they represent only oneassembly. A custom part can only be added to a precast member if it is correctly defined as anassembly. Custom parts can not be split into different precast members; each custom partmust go in onlyONE precast unit.

Use the inquire assembly command to always check to see this is properly defined. See belowfor color coding chart:Inquire >Assembly -command

Material Main Part Secondary Parts

Concrete: Magenta Cyan

Steel: Orange Yellow

Other/Miscellaneous: Orange Yellow

Rebar: White n/a

E.g. Column Base Plate AssemblyBase plate and rebar are added to same precast piece together; therefore, they are defined asone assembly and added through out as a custom part.


6/74


Defining Assembly Hierarchy

E.g. Anchor AssemblyThe anchor rod, washer, and nut are all part of the same assembly that iseither prefabricated or assembled on site and put into the same cast unit.

Since it is in the same cast unit (precast or cast in place) it is all in thesame custom part. These objects are welded together so that they defineone unique assembly and so that they can be added to the cast in placefooting or precast column as one unit, by adding the custom part as subassembly.

E.g. Spandrel Tie Back Sleeve AssemblyIn this illustration the plastic sleeve is one custom part by itself. This is because only it isadded to the column. Theshim and column spandrelplate are not added to the

column and therefore not allpart of the same custom part.The shim will be its owncustom part since it is notadded to any assembly. Thestud plate will be a thirdcustom part since it is added tothe spandrel assemblies.Using this method the parts are broken up into smaller units that are managed based on whichelements go into which cast unit. This is the method that should be used for deciding whichelements are in which custom parts.

Each assembly can have one and only one main part. To properly define this main part it mustbe the first part you pick when using the weld tool. The main part is the part to which allother objects are welded or attached (rebar). All other objects should be welded (attached ifrebar) to this one main part. Make sure to have the weld tool setup as shown below forcreating embed assemblies. Weld Settings for Embeds:

Orientation

It is recommended to model the plate stock information first (as the profile) and length as thepick handles for the steel beam. This will give correct and consistent report output. Thisassumes you will want the least expensive steel stock to be used. E.g. PL 3/8" x 4" stock 12"long vs PL3/8" x 12" x 4" long.

Note: To get the "PL" prefix you will need to set the advanced option, see below. This is

located in the "Plate work" section of the advanced options. Default is "FL". XS_FLAT_PREFIX=PL

Pick Handles

Choose the pick handles of thecustom part carefully. Thesehandles will determine how thecomponent behaves in themodel. The rotation along theprofile is handled automatically

when creating customcomponents, however, the tiltalong the piece is not. Definethe handles in such a way toallow manipulation of thecustom part to follow the Precastmember. In the illustration it isclear how the handles of thisembed need to be defined; tofollow the tilting of members

along their handles. The red field plate has its handles defined into the page; therefore, it cannot follow the beam tilt with bindings.

Generally, the handles need to be defined in the same plane as the main part or how it is to beinserted. Always choose two handles to define your custom part. The part will be

automatically be positioned based on the center of the extreme limits of the parts thatrepresent the custom part, as long as theUse the center of the bounding box in positioningis chosen (default).

This option allows the embed to be centered even if the pointspicked are not exactly in the center of the part(s). This willallow the positioning tab to function properly in the model forthe custom part. Disabling this functionality by un-checkingthis box will no longer automatically center the position planesfor the part; instead, it will use the two handles defined to

determine the center. The locations of the handles pickeddefine the center, middle of the assembly.

Default handle location:

As long as this box is checked, custom parts with handles picked not in the center, middle willautomatically have an offset entered for the handles. The center of positioning planes willautomatically be calculated. The handles picked are then offset from the center of the part inthe dialog box. See below for an example.


9/74


Embed Setup

The 1st input handle could be in thecenter or edge of the custom part. Ifthe start handle is in the center of thepart then dimensioning to thisreference point (start handle) ispossible.

Note: Choose as secondary objectsand it will dimension both ends

instead.

Note: Always set the positionused in most cases and create a"save as" of the custom partnamed "standard". This will thenbe used for inserting futurecomponents. The "standard" is thedefault used unless another settingis applied to the system first.

Rebar

Always use reinforcement tools for modeling rebar, lifting hooks, DBA, strand, etc. Rebar ismuch lighter in the model than round beams and this will have a large impact on performance.

Rebar is handled differently in the model and in templates than beams, so be sure tocoordinate this with your templates with model practices. When copying rebar always checkthe assembly to make sure it is attached to the proper part. If rebar is not part of the assembly,be sure to select the rebar and attach to the correct part manually. If the rebar is always usedwith the embed or lifting device then it should be modeled in the custom part for mostefficient use and model consistency.

Embed Setup

Studs, Holes, and Bolts

Always model studs, holes, and bolts with the "Bolt" tool. These elements are considerablylighter in the model. Bolts are handled differently in the model and in templates than otherobjects. Use the "PC_Hole" and "PC_Stud" presets to guide you

in using the correct settings. It is important to make sure thebolt type is "Workshop" for studs on plates. This affects thereports and drawings as well.

Note: Bolts do not change color when you inquire the assembly; they do no exist loose in the

model they are always attached to an assembly.

Presets

There are included presets in the system for modeling embeds. Use these unless you alreadyhave your own integrated modeling and template system setup. For creating embeds alwaysuse the steel toolbar. Add to this list of presets as necessary and make sure to coordinate thesesettings when making your templates. Make sure each user models embeds consistently usingthe same settings.

These presets distinguish the class for the different types of embeds

and model objects. This system makes checking the model andfiltering drawings and reports easier. It is also recommend that thesecondary parts of multiple part embed assemblies be modeleddifferently so there will then be a mechanism that can be used to filterthe secondary and primary parts more easily. Modeled correctly, youwill be able to visually see in the model which is the main part andwhich embeds are correctly defined as precast or other.

It is best to store the identification name or number in the "Name" field. A different identifiercan be stored for each plate or part in the assembly if you wish. The main identification to beused in the drawings and reports should be in the "Name" field of the main part of that

assembly. Some parts are best called out using a description rather than a profile and length; aUDA field should be adopted for this and referenced in the templates where applicable. Useone of the existing user defined attribute fields or create one by modifying the objects.inp anduse this information in the reports or drawings. See below for an example.

Make sure only the concrete parts are modeled with the concrete tools in Tekla.

Steel tools and concrete tools have different information and presets associated with them.When working with any part that is steel, it needs to be defined as a material available in yourmaterial catalog in the "Steel" section. If the part isplastic, steel, neoprene, or anything other than concreteit should be modeled using the steel tools and use amaterial in the "Miscellaneous" or "Steel" section ofyour material catalog. You might need to add some materials to your catalog.

Note: If the material is not properly defined or in the material catalog it will not performproperly in the model or drawings.

Accuracy

Remember the goal when modeling embeds, especially vendoror standard embeds is to show the placement in drawings. If the

embeds are not fabricated from the Tekla drawings then themodeling of the parts can be simplified. Include only enoughdetail that they show clearly in the drawing for production toplace them but not more detail than is easily seen. Always keepheavily used model objects as simple as possible. Custom partsare used many times in the model so the more parts, handles,parameters, intelligence, and complexity the more data heavythe project becomes. Avoid unnecessary detail and complexityfor the best model, report, numbering, and drawingperformance. Try to avoid putting cuts in as part of customparts if possible.

Round objects, chamfers, curved beams, part cuts, and otherfine detail should be avoided if possible when creatingstandard or catalog embeds. Remember these embeds are usedextensively in the model so any small changes you make tohow simple they are modeled can have a large impact on theperformance of your job.

Parametric Ab ility

For standard and vendor embeds there is no need for formulas, bindings, parameters, and otherparametric ability. They do not change often and there are a set number of them in a catalog.It is much better to create a save as of the custom part and adapt when creating a new part. Bykeeping these embeds simple it cuts down on unnecessary work in the model. This can have alarge impact on performance.

General Suggestions for Properties

- Product name (e.g. P01 ) =>Main part name- Order number (e.g. 05.337.032.430A) =>Comment

- Treatment (e.g. G for galvanized) =>Finish-field- Description (e.g. 8T BURKE ANCHOR HEAD) =>User field 1- Class varies per type of embed- Numbering series:

- Part prefix: EB_name (E.g. EB_P01), Start number 1- Assembly prefix: EB_name(E.g. EB_ P01), Start number 1

Note: Numbering series are unique for each product name in order to make numbering fasterfor standard parts (difference is found easily, no need for solid comparison)

Catalog Name:It is recommended you prefix the embed with EB_ or Embed_ and then add on the ProductName (e.g. EB_ P01). This makes them easy to filter and use in the component catalog.

Foreword

Foreword

The purpose of this document is to recommend procedures for the proper setup and use ofnumbering for the Precast industry. Once mark and piece information are released on aproject, it isNOT recommended to change numbering setup. It is not recommended tochange settings that affect numbering during the course of the project.

In order to get the best Precast numbering results, objects must be modeled using standardsand put in the model consistently. Also, in the case of tees, the lengths vary to achievewarping. For concrete parts, careful consideration must be used when assigning thetoleranceand this must be consistent throughout the project.The tolerance should never be set tozero. It is recommended to use a tolerance that is reasonable to allow slightly longer tees or

other tilted parts to get same mark if this is the desired result. Be careful not to choose atolerance that is so large that concrete parts get the same mark even though they are trulydifferent cast pieces.

When working inmulti-user modecare must be taken with numbering and modeling toachieve consistent Precast results. Numbering should be the responsibility of one person toavoid multiple users numbering at different times. Numbering must be coordinated at alltimes. When numbering is run, make sure that it is run on a model that is fully up to date.This requires that all users save sequentially and then the one person who is responsible fornumbering must save last, number, and then save the results. After the model is numberedthen it should be saved immediately so others can get the results.

Numbering setup can vary from project to project and must be reviewed by each company.Settings can vary depending on desired outcome. The numbering settings suggested in thisdocument should be a good starting point to achieve consistent numbering. Pay specialattention to each option in the dialog box, each option can make a large difference in theresults. Keep in mind that the rebar_config.inp file also affects how rebar is marked andnumbered as well as several advanced options for numbering. The tolerances in the setup filesand templates should match what you have in numbering setup.

The tolerance entered for each material is used for all aspects of the part's geometry. Thisincludes length, width, height, block outs, embed locations, rebar location, and all other

geometry. Also keep in mind that nested sub assemblies have their own marks as well asrebar. For any two cast units, if the marks of embedded objects are different then the castunits must also be different.

Numbering should be used to help check the model starting from day one. It should not bepostponed until right before you need to release drawings. If you use it daily it will help youcheck and fix you model as you go. If there are extra marks it is a good idea to go ahead andfix the model inconsistencies at that time before moving on.

A. First numbering setup

A. First numbering setup

This occurs when you reach a certain point in your project where most of your pieces aremodeled, usually the first few days. Numbering has been done before but no drawings/markshave been released for final coordination. Like parts (parts that need to have the same marknumber) should be detailed the same for best results. The numbering setup used at this pointis unique, see below. At this time, all pieces are renumbered and old numbers are reused toavoid gaps in the numbering sequence.

Numbering Steps:1. Setup numbering as shown above.2. Click Apply.3. Go to Tools>Numbering>Full numbering.

4. Verify that the numbers came out as needed.5. Change numbering to "PC_standard" settings, see section B.6. Rename "PC_Standard" to "standard". This is a critical step!

Modified numbering does not remark parts that have not changed. In order to remark all partstaking into account new settings, full numbering is needed. Full numbering will check allparts against applied numbering settings, whereas before now settings were not probably setor consistent. From this point forward numbering modified will be the primary numberingmethod.


18/74


B. Numbering after marks have been released for coordination

B. Numbering after marks havebeen released for coordination

This generally occurs when preliminary marks and drawings are released to architect, owner,and/or contractor. Marks will change some because not all pieces have been fully detailed andit is necessary to add or remove some pieces at this stage. It is OK for some minimal markchanges if detailing requires it. It is important at this stage to number carefully. It is best notto number when all like elements are not detailed to the same stage. For example, if fourspandrels need to have the same mark but only one of them has reinforcement then it is bestnot to number until all four spandrels have the same reinforcing and connections. From this

stage forward you will want to use modified numbering and avoid numbering setting changes.This procedure will help to avoid unnecessary mark number changes during the project afteryou have set numbering. Do not change numbering settings during the project; this willadversely affect your numbering system.


19/74


C. Clearing Marks

If marks are different for cast units that should ideally be the same, you can clear numberingfor those pieces only and then run numbering modified. This sometimes is the case whennumbering was run at times when the detailing of like parts was at different stages or differentsettings were used. The clearing of the marks will force those pieces to all be re-comparedand remarked against the other pieces in the model. If no parts are modified, numberingmodified will not give them new marks or re-compare the pieces.

It is not recommended to run numbering full in a project after marks have been releasedbecause this could result in more mark changes than desired. If this process does not result inthe cleared parts receiving the same mark then there is something different about the pieces in

the model should be fixed. You should compare the inconsistent pieces using reports anddetermine what is different. See below for steps for clearing marks so that certain pieces arere-compared.

To clear marks and re-compare certain pieces from scratch:1. Select desired parts to be cleared.2. Go to Tools>Numbering>Clear selected.3. Run modified numbering.

Most Common Model Inconsistencies: (forcing extra marks)

1. Duplicate custom components2. Duplicate rebar3. Objects were at one time modified using objects in components4. Unique or different user defined attributes5. Parametric profile (including parameters) are different6. Different numbering settings for prefix or start no7. Changes in numbering setup was made at some point8.

Foreword

Tekla Structures is very flexible and allows you to place pieces in the model in various ways.In cases where these pieces are all symmetrical and all faces of the piece are the same thenthere is no need to consider orientation and the top in form setting; however, when workingwith Precast it is essential to set these properties correctly to get the desired results.

How you model parts affects how drawings are created. If you have set up numbering toignore beam and column orientation then the piece orientation will not affect the marks;however it can still affect drawings. It is important to understand how the various modelingtechniques and settings will affect your drawings. If care is not taken you can get differentdrawings for pieces other than what you might have intended. When you create a drawing of

a cast unit you must select a part of that cast unit in the model to generate the drawing. Thisnewly created drawing is of that particular piece you selected in the model.

The Tekla numbering system links the drawing of that particular cast unit to all the otherpieces in the model with that same mark or the assembly position. The cast unit position orassembly position number represents the identifier of that product commonly referred to as the"mark number." If you have numbering settings that lead to truly different pieces in the modelreceiving the same mark then your drawing might not be representative of all members of thatassembly position. This is where the top in form setting, orientation, and proper modeldiscipline can help.

One of the most common examples is an exterior column. It is important to consider themany finishes of pieces in Precast. Different faces of the column will likely receive differentfinishes. The exterior will have a more refined finish when exposed, making the exterior faceimportant and unique. You will most often want to see the drawing taking note of the finishesof the piece, particularly the top in form or the up face of the piece. The more processedfinish is often achieved by being designated down in form. It is common to show this down inthe drawing view, as it were cast. This same mechanism can be achieved in Tekla Structuresdrawings.

For two columns on opposite sides of a structure (or any other type product) they are bestmodeled as rotated elements. The easiest way to see this is to consider how the piece is

typically erected. This piece "A" is exactly the same as on the other side of the buildingexcept it is rotated, not mirrored or copied. The finished face remains exterior; therefore thatface of that piece should remain exterior in the model as well. There are several ways ofaccomplishing this in Tekla Structures.

The goal is to model the pieces so that the drawings are consistent regardless of which piece isused to generate the cast unit drawing. It is important to get the correct up face in thedrawings so you do not have to spend time creating extra views and unnecessary editing in the

drawings. This user guide is aimed in explaining how these goals are easily achieved and tomake suggestions on how to get greater overall consistency in modeling and in drawings.

Working with ColumnsRecommended Column Model Orientation:

For the purposes of this document the view names are shown below.

The default top in form face is "Back" for columns. To illustrate let us see what "Front"would do as a default.


25/74

This affects drawings only if the view orientation is set to"Fixed" and only if drawings have not already beencreated.

Column Drawing (generated with top in form=front):

In this case, columns are modeled as shown in orientation recommendation picture and havedefault top in formUDA (user defined attribute). Because of this reversed orientation, allcolumns in the model yield the same drawing as shown above. Reversed orientationindicates that each opposite side of the structure has the elements with opposite orientation.This effect is achieved withCopy SpecialRotatecommand. If the columns are insertedusing theCopy SpecialTranslatethen this effect is not achieved automatically, but canbe achieved by manually changing the orientation as shown in picture.

Having the correct orientation does ensure that pieces are modeled in a Precast friendly wayand that the drawings will be consistent. It does not guarantee that the drawings will have the

desired orientation. To make sure the orientation is correct we will need to work with both therotation and the top in form face user defined attribute.

Top in form face user defined attribute


26/74


If we change the top in formUDA to Back, and create anew drawing, this is the resultingcast unit drawing. This UDAdoesnot affect existing drawings

if changed after the drawing iscreated. Drawings must berecreated or regenerated to takeinto account this setting.However, the view can berotated manually or by using theview properties to achievedesired result. It isrecommended that you preset theup in form or "Front" view inthe model and apply the same

"Top in form face" UDA to eachof the columns in the same groupor mark.

To get the corbel to be in the down in form face you will need to designate the top in formface UDA to Back". When a new cast unit drawing is created using this setting the corbel isnow shown on the down face (far side) of the column and it is flipped on the Up in Formview. We are designating the front face by using this setting. It is a method for pinning thecorrect face in the model to the correct face in the drawing which also affects rotation of theviews.

We notice that the corbel is now down in form inthe top view; however, we want the corbel in thebottom view to be shown down on the drawingpage. We can not just take "Side B" and draw thecorbel down because that would not correctlyrepresent the model, but we can choose to show theother side view instead, which would show thecorbel down on paper. To show the other side of thecolumn instead you can turn on the "Bottom" viewand turn off the "Top" view.


27/74


Once the view position is set, you can get all the correct views in the drawings and orientatedas well. The default is setting for columns is Column_Form versus say the Beam_Form whichhas different view scales, views shown, and rotation perhaps. The objective is to get thedrawing as you need it be shown on paper and to clone where Tekla can take into account theediting of this one drawing and apply it to other similar pieces. For the section views you willwant to rotate those in the master drawing so that the "Up in Form" is up on the page, this willthen clone to the other drawings.

To get consistent modeling and drawing results we will want to make sure the pieceorientation is opposite and the top in form settings are the same. The top in form face settingyou use will depend on which face you want to designate as up in form. Below are someexamples:


28/74


Note: In the below pictures the section has been expanded to see entire column length whichwould not be typical, this is done to show more clearly how corbel and sides interact.

Top in Form=Front

Rotation=Front

Rotation=Front

Top in Form=TopRotation=Front

Top in Form=BottomRotation=Front


29/74


By using the "Top in form face" UDA you are able to preset which face of the object you wantto be used for the "front view" in the drawing. For the Precast industry, this will translate tobeing able to fix the drawing up face orientation to a particular side of that piece in the model.This assumes that you will want to draw the piece with a view in the drawing showing whatthe worker actually sees standing over the piece in the form. From the picture below you can

see which face to assign depending on what side you want up in form.Looking below it is clear that we would want to link the "Front" or up in form view in thedrawing to the "Back" model view. This would cause the corbel (shown in blue) to be drawndown on the drawing page and shown on the far side in the up view.

The faces are generated in this order: Front>Top>Back>Bottom, in a clockwise fashion. Inaccordance with our view names this will translate into: Up in Form>Side A>Down inForm>Side B, in this same clockwise fashion starting from the side we designate as Top inform face. In the case where we set top in form UDA to "Back", then the Up in Form viewwill show the "Back" face up in the top drawing view. Then in a clockwise fashion the next

face "Side A" will be the model face Bottom view, as shown in the pictures on the previouspage.

If you prefer your base of the column to be drawn on the right side of the drawing instead ofon the left then you can use the below "Around Z:" setting to rotate the part in the plane of the

page. Rotating the views around the drawing z axis 180 degrees will cause the base of thecolumn to be always shown at right for columns.

Working with Walls

Walls work in the same manner as columns but have slightly different face positions due tothe location of their handles. If you model your walls as recommended in Tekla basic trainingand use the recommended model discipline then this will be consistent and simple tounderstand.

This is how the wall properties are setup for this document:

Wall placement in model:

Set the Top in form face UDA to show which side of the piece that you want drawn up inform. If you want the top in form to be the "Back" face then set this UDA to "Back" for thiswall. This will designate the "Front" to be the "Down in form" side and be shown down in thedrawing, see below for illustration.

In the above case, you will notice that the wall is upside down. We would prefer the top ofthe drawing to represent the top of the wall as erected. To get the drawing to rotate all partsautomatically we can use same method as for columns and beams. We will set the rotationabout the z axis for walls to 180, see below. For the section views you will want to rotate

those manually in the master drawing so that the "Up in Form" is up on the page, this will thenclone with drawings for the other walls.

Rotating about the Z (in and out of the page of the screen) changes the drawing to match whatis shown below.

14 TEKLA STRUCTURES PRECAST Copyright 2007 Tekla Corporation 1Working with beams (spandrels, IT beams, tees, etc)

Working with beams (spandrels,

IT beams, tees, etc)Beam elements work in the same manner. If you model your beams, spandrels, and tees asrecommended in the Tekla basic training and use the recommended model discipline then thiswill be consistent and simple to understand.

Here is the setup used for beams:

For beams, you will most likely want to show the "Up in Form" as the top of the piece lookingdown into the bed it is poured in. To accomplish this we will want to set the "Top in formFace" to "Top," as seen on the next page.

The resulting drawing will be shown as below.

The section should bemanually rotated in yourmaster drawing and thencloned for the other beamdrawings to accomplish topin form top of pageconcept. Using thesemethods, it does not matterwhich tee you select in themodel to generate the castunit drawing, each will yieldthe same result (assumingyour exterior tee bays aremodeled from outside in, aswith beam standardmodeling practice).

If you want to have the exterior end of the tees on the right side of the page you can set the

rotation about the z axis to 180, as with columns and walls. Be aware that "Side A" and "SideB" will reverse in the drawing by doing this. This is because you are not switching which

view you are looking at in the drawing,only rotating them. If you do not wantto switch "Side A" and "Side B" youcould also rename the "Top" and"Bottom" view name for beamdrawings.


36/74


Sides for beam orientation: (Finish handle is into page)

If you are looking at the other end of the beam (Start handle is into page) the "Front" and"Back" sides would be reversed. IT, rectangular, and ledge beams will all behave in similarmanner. Depending on your standards, you might want to do a preset for each product type toensure the correct views are correct in the drawing from the start.


37/74


Here is the setup used for spandrels:

Other example: (Finish handle is into page, modeled clockwise)

Model Faces:


38/74


For the spandrel drawings you will most likely want to turn off the bottom view, this waspreset but could be setup as turned on instead. You can see from this example that you caneasily do presets for each product type and get the desired views and orientation from the start.The views can also be renamed in case you want to make the names more sense based on

product type.

There are presets for the following: Beam Spandrel Column DoubleTee Slab VertWall (for slender vertical walls or ramp walls) Wall (for shear walls or longer horizontal walls)

Necessary Advanced Settings or user.bat:

set XS_OMIT_MARKS_OF_HIDDEN_PARTS_IN_GA_DRAWINGS=(The above setting is blank, anything else prohibits hidden part marks)

set XS_PART_MARKS_ALWAYS_VISIBLE_IN_DRAWING=CG(The above setting allows marks to be shown if entire part is hidden in certain drawings)

Merging Mark Settings:

set XS_MAX_MERGE_DISTANCE_IN_HORIZONTAL=2134 set XS_MAX_MERGE_DISTANCE_IN_VERTICAL=2134 set XS_PART_MERGE_MAX_DISTANCE=2134

(Remember 2134mm =7ft, consider tee stem plates if you want these marks to merge inelevation views)

Suggested Drawing Part Mark Settings

Suggested Drawing Part Mark

SettingsIt is recommended that these settings be used in thedrawing properties for GA drawings. It is often bestto work directly with views, especially if there aremultiple views in one drawing. It is recommendedto add mark content through the view propertiesinstead of through the drawings properties. Thesettings in this document show how to setup thedrawings and views to have marks properly comeinto the views. Once in the mode of editing at the

view level, it is not recommended to go back andchange properties on the drawing level.

Suggested View Part Mark Settings:

Part mark categories

Part mark categories

General Note

The above settings work well for details, sections, and small areas where all embeds are called

out. For large GA drawings where only certain embeds or certain part marks are called outyou can use associative notes or use part marks though classifier systems. It is often easier tocall out only the parts you need rather than call out all marks and delete the ones you do notneed. The most efficient way to handle marks in plans, elevations, and other large scaledrawings is to develop a system of classifiers that automatically calls out only the marks youneed. There are some presets available to you as a guide included in the view presets called_PC_Plan and _PC_Elevation.

See Help: The Drawing Classifier

Marks for Grouped Items

Marks for Grouped Items

For cast unit drawings there is another setting that affects how marks are shown in drawings.In the "Cast unit drawing properties>Dimensioning, the menu below appears. Under the tabDimension grouping there is a setting to not show certain part marks. If the box highlightedbelow is checked it will prevent marks from coming into drawings for cases where they wereor are marks included in a dimension line tag as part of the automatic dimensioning.

Foreword

Foreword

This document is a guide to help you correctly setup Rebar marks so drawings are generatedcorrectly. Remember your

advanced optionsserver_user.batuser.bat, andusimp_env.bat

all affect how Tekla Structures works. They take precedence in that order.

Optional Settings to consider

XS_CONSIDER_REBAR_NAME_IN_NUMBERING=TRUEXS_REBAR_CLASH_CHECK_BENDING_TOLERANCE=0.5See help for more information on each of these settings.

Numbering Settings

Rebar is marked according to its Prefix and Start No from the tool used to input it into themodel. If necessary, no "Prefix" need be assigned, this would result in 1, 2, 3 instead ofR/1, R/2, R/3. The content part of the position number can be broken up or used to createrebar marks that are different than the position number if desired. The "position" number is

the prefix plus the numbered suffix. It is good practice to use this mark to refer to the rebar inthe view and then reference more information in the bill of materials or a rebar schedule.

WARNING: You should not usedifferent start numbers that areclose together in the same model.If you have some rebar starting at 1and other rebar starting at 100 it isvery possible to see the warningmessage "Overlapping RebarSeries". This warning means you

have 2 or more rebar with the sameposition or mark. This could result

in detailing errors and fabrication errors. It is easiest tostart all bars at 1. However, if you do not use this methodmake sure there is ample room between numbering seriesto cover all variations of rebar in the model.


50/74


Reinforcement marks

Reinforcement marks

Many drawings use multiple views and have unique view settings. It is best to set rebar marks

in the view properties. The view and drawing properties have to be set to work together. Besure to save these settings as a preset once you get it correctly setup. This document works forboth GA and CU drawing properties, the menus vary slightly but the setup is the same.

Drawing Properties

This dialog illustrates how to set the drawing settingsat the drawing level. It is most efficient to turn themarks off at the drawing level and turn them on onlyfor the views which you need to see marks. There is

some content in this setup to avoid empty marks fromthe drawing level.


51/74


Reinforcement marks


52/74


Reinforcement marks

View properties:

The dialogs below illustrate how to set up view properties to show rebar marks correctly.When you are dealing with rebar groups they get reported as one mark. In order to havequantity you will need to have "number" and "position" for group marks. Be sure to save this

away as a preset once you get it correctly setup.


53/74


Reinforcement marks

Using these settings, new views would result in the below drawing view:

The rebar marks as shown in section"B" are merged horizontally on thepage. These can be set to mergevertically instead. There is no optionthat will merge all four bars at cornersof beam automatically. If parenthesis

are preferred in group marks these canbe add with text "(" and ")" to thecontent around the "number" field.


54/74


Reinforcement marks

If merge marks are not needed in thatview, set the properties as shown to theleft.

Note: The merging settings of the view can NOT be changed after creating the view to havethem re-merge. These must be preset for the merging to work properly before view is created.Once they are set to "No merge", they will not go back and re-merge. The same applies to the"Preferred direction of merge"; this must be preset to work properly. The "Identical marks insame cast unit:" feature can be changed after the view is created and the marks will readjustaccordingly.

Note: "Block prefix", "Single mark content", and "Symbol separating" content must be set asa minimum for merged marks to work properly. They need to be in the order as shown above.

Note: You will need to preset these rebar mark settings for views in which rebar will be used.The view settings will clone when working with the CU drawings. The same view propertiesare available for both CU and GA drawings; however, it is best to do presets for eachseparately.

Precast Session II- The Precast Workflow


62/74

2007 North American User MeetingPrecast Session II

www.tekla.com | 1-877-TEKLA-OK

The Precast Workflow

In this session we will go over the impact BIM technology has on the traditionalPrecast concrete fabrication workflow. We will first discuss what BuildingInformation Modeling is and how it is being employed in other constructionsegments. After defining the Precast workflow we will discuss what role BIMcurrently plays (if any) and what role it might play in Precast fabrication in futureyears. We will then discuss what Tekla and Tekla Structures brings to this segmentand how BIM can be implemented. Various methods will be discussed for gettingmore out of BIM software by adapting your workflow and by realizing BIM isnot yet the standard in Precast. We will hear from some customers and theirexperiences in implementing Tekla Structures and how they perceive BIM.
