Extracting Views

As in a real life situation you will start thisdrawing from a 3D unprepared model. Thismeans that you will:

Modify the screen definition,

Select the working convention,

Create a front view, Create a right view,

Create a section cut,

Create a detail view

Create a breakout in the detail view.

Modify the Screen Definition

Since your starting model is notprepared, you will have to modify thescreen to split it into two windows:one for the Space model and one forthe cartridge. Define the screenselecting the elements shown belowin the prescribed order:

Notes :

Preparing the DrawingSheet

In the first part of the exercise you haveextracted several views. Now you must putthem in a drawing format and prepare thedrawing before adding text and dimensions.

You will thus: Retrieve the reference view,

Retrieve a drawing format from a library,

Clean up the drawing.

Retrieve the Reference View

Before adding a drawing format youmust retrieve the reference view fromNoShow, because you will use it asthe origin of the drawing format.

NS sw i t ch

The reference view is displayed inShow. *VU1 is the default Draw viewgenerated by CATIA when the initialmodel is created.

Create additional mark up geometry,

Create text,

Modify the drawing format information.

Select the Dimension Standard

Before starting to dress up the views,you must select your workingstandard. Here we will choose theIS Ostandard, but you can choosethe ANSI, the DIN , the J IS or theASMEstandard. This is how...

Creating Two PrincipalViews

In this part of the exercise you will:

Create the left view,

Create the top view

The Pr i n ci p a l v i ew option allows you tocreate the top, bottom, left and right viewsusing the current view as reference. Thecurrent view is identified thanks to a redcircle displayed around the origin.

Create the Left View (1)

First you must select the relevantoptions in the displayed windows.

AUXVIEW2

USE

Red temporary lines are displayed onthe face view. They allow you to locatethe different areas of the view you

wish to create.

Notes :

Create the Left View (2)

Now you must indicate a point on theright-hand side of the face view tocreate the left view. We are using theEuropean standard (first angle.)

AUXVIEW2

Notes :

Creating Section View A/A

There are two ways of creating a sectionview or section cut:

If you want to create an associativesection, start with a selection. This is

what we are going to do now.

If you want to create a non-associativesection, start with an indication. This is

what we are going to do in the next part.

Create Section View A/A (1)

You are going to create a projectedoffset section view with the left viewas the origin. The cutting plane willgo through the upper, the middle andthe lower drillings. First select the left

view to make it current.

AUXVIEW2

You will now change the length of thesection arrows. To do this you must

first select the section view profile.

CREATE + ROUGHNES

The advanced roughness symbol iscreated. You can link a roughnesssymbol with more than one surface

when you create i t or as amodi f icat ion us ingT E X T D 2 +MODIFY + LEADER + ADD.

You have completed the exercise.Donot forget to save your model.

Conclusion

In this exercise, you have learned:

To create dimensions for different cases ofdistance, radius, angle and roughness.

To generate basic texts and tolerances. To

get used to these options, you will have topractice them a little more!

Modifying DimensionLines

In the first part of this exercise you will:

Modify an angular dimension,

Modify a diametric dimension line,

Align a distance dimension.

Modify an Angular Dimensionin a View

First you are going to modify theposit ion of the 30 degree angle

dimension in the Right View.

Move a Distance Dimension

You wi l l now move the 15mmdistance dimension value in Section

AA.

MODIFY + VALUE + LOCATION

You have moved the dimension value.Repeat the operation for the 22.5mmdimension in Section AA. You canpress the YES: RESTORE key at anytime to restore the initial location ofthe selected value.

You have moved the dimension value.

Indicating FakeDimensions

In this part of the exercise you will learn to

indicate not-to-scale (fake) dimensions.

Notes :

Indicate a Not-to-ScaleDimension

Now you will define a fake valuebased on the 11.8mm value in

Section AA.

DIMENS2

MODIFY + VALUE + FAKE DIM

The fake dimension is created.

Warning! Be carefulwhen you usefake dimensions: subsequent users of

your model wi l l ignore thed imens ions and on ly use thegeometry. This might cause errors inmanufacturing, assembly, simulationor FE analysis.

Breaking Extension Lines

In this part of the exercise you will learn to:

Indicate break points,

Define the gap size, Break all extension lines.

Notes :

Indicate the Break Points

Before starting note that if you selectthe d imension va lue i tse l f , a l lassociated lines will be broken, but if

you select an extension line, only theselected line will be broken. Nowselect any one of the extension linesassociated with distance dimension15 in Section AA and indicate two

break points.
