Lesson 3: Cleaning Up Maps

You can use the Autodesk Map drawing cleanup tools to improve the quality and accuracy ofyour maps and correct errors caused by digitizing, importing, surveying, inaccurate drawing,and so on.

You use the drawing cleanup tools in the following ways:

Check maps before linking objects to databases.

Prepare maps before working with topologies.

Find and remove map errors, such as duplicate objects, undershoots, and overshoots, so

that your maps are accurate.

When you use drawing cleanup, you can choose whether you want Autodesk Map to correcterrors automatically, or if you want to review the list of detected errors so that you can correct,mark, or remove errors interactively.

In addition, you can use drawing cleanup to simplify objects, which eliminates unnecessarycomplexity. This is useful when plotting large, complex maps on a small page, or if you wantto reduce the file size of a map.

Exercise 1: Clean Up a Map and Review Errors Before Correcting Them

In this exercise, you clean up a digitized street map. You check the map for common digitizingerrors, including duplicate objects, undershoots (gaps), and dangling objects. Then, you reviewthe list of detected errors and correct and mark errors interactively.

1. From the File menu, choose Open. Navigate to your MapTut\Tutorial II folder andopen Streets2.dwg. Streets2.dwg is a digitized street map for a proposed new housingdevelopment.

2. From the View menu, choose Zoom > Extents to view the whole map.3. From the Map menu, choose Tools > Drawing Cleanup.

The Drawing Cleanup - Select Objects dialog box appears, where you specify theobjects you want to clean up and the objects you want to anchor. Anchored objects arenot altered during the cleanup process and are used as reference points for cleaning upother objects. For example, you can anchor survey points that are known to beaccurate.

To select and anchor objects for cleanup

4. In the Drawing Cleanup - Select Objects dialog box, under Objects To Include InDrawing Cleanup, make sure that Select All is selected, and for Layers, make sure thatthere is an asterisk (*) in the box. With these options specified, Autodesk Mapconsiders all geometry in the map for cleanup. Note that Autodesk Map does notconsider objects on layers that are frozen, locked, or OFF.

5. In this exercise, you don't need to anchor any objects, so accept all other default values,and then click Next. The Drawing Cleanup - Select Actions dialog box appears, whereyou specify the types of errors you want to clean up and the settings you want to usefor detecting errors.

To select and set up cleanup actions

6. In the Drawing Cleanup - Select Actions dialog box, in the Cleanup Actions list, clickDelete Duplicates. Press CTRL and click Extend Undershoots and Erase DanglingObjects so that the three actions are selected, and then click Add to add them to theSelected Actions list.

Cleanup actions listed in the Selected Actions list will be performed on your map inthe order they are listed.

7. In the Selected Actions list, verify that the cleanup actions are listed in the followingorder: Delete Duplicates, Extend Undershoots, and Erase Dangling Objects. If youneed to change the order, select the action you want to reposition in the list, and clickthe up or down button.

8. In the Selected Actions list, select Delete Duplicates, and enter 0.1 for the Tolerance.

This tolerance value tells Autodesk Map to consider all objects within 0.1 drawingunits of each other as duplicates. Autodesk Map does not use a predefined system of

7


8/44

unit measure such as meters or inches. For example, a distance of one unit mayrepresent one centimeter, one foot, or one mile in real-world units. When you create amap, you decide what one drawing unit will represent, and then create your map withthat convention. In Streets2.dwg, one drawing unit represents one meter.

9. In the Selected Actions list, click Extend Undershoots, and enter 15.4 for the

Tolerance.

In this map, a tolerance value of 15.4 means that if two polylines pass within 15.4meters of each other, they will be snapped at their closest point. If no node exists atthat point, one will be created.

10. In the Selected Actions list, click Erase Dangling Objects, and enter 10.5 for theTolerance.

11. Under Options, select the Interactive check box to indicate that you want to review thelist of detected errors so that you can correct, mark, or remove errors interactively.

12. Click Next to go to the Drawing Cleanup - Cleanup Methods dialog box, where you

specify how modified objects are handled.

To specify how modified objects are handled

13. In the Drawing Cleanup - Cleanup Methods dialog box, under Cleanup Method, makesure Modify Original Objects is selected. Then, clear all the check box options.

In this exercise, you modify the original objects, but you could also create new objects,and retain or delete the original objects.

14. Click Finish to check the map for errors and display the list of detected errors in theDrawing Cleanup Errors dialog box.

To review and correct errors interactively

In the Drawing Cleanup Errors dialog box, the first cleanup action, Delete Duplicates, ishighlighted in the list.

15. Click the plus (+) next to Delete Duplicates to see how many duplicate objects weredetected: Error 1 of 10.

16. Click Error 1 of 10.

In the map, the first error is displayed with a temporary marker on it so that you canfind it easily.

17. Click the Fix button to correct this error and proceed to the next error.18. Continue clicking the Fix button until you've deleted all duplicate objects.

Tip: If you want to fix all duplicates at once, click Delete Duplicates in the list andclick the Fix All button.

8


9/44

When you are done correcting duplicate objects, Extend Undershoots is highlighted inthe list.

19. Click the plus (+) next to Extend Undershoots to see how many undershoots weredetected: Error 1 of 25.

20. Verify that Extend Undershoots is still selected, and then click the Mark All button to

place markers on all detected undershoots.

The errors are not corrected, but markers are placed on them so that you can find themlater and review them more closely.

21. Click the Next Action button.22. Click the plus (+) next to Erase Dangling Objects to see how many errors were

detected: Error 1 of 3.23. Click Error 1 of 3 and then click the Fix button three times to correct the three

dangling objects detected.24. Click Close to make the specified corrections.

Now you know how to set clean up options to detect map errors, and then review thedetected errors, place markers, and make corrections interactively. In the next exercise,you learn how to have Autodesk Map correct errors automatically. Leave the mapopen, because you use it in the next exercise.

Exercise 2: Clean Up a Map and Correct Errors Automatically

In this exercise, you continue the cleanup process started in exercise 1. You correct morecommon digitizing errors, but instead of reviewing errors before correcting them, you haveAutodesk Map correct the errors automatically.

1. Make sure that Streets2.dwg is still open from the previous exercise.2. From the Map menu, choose Tools > Drawing Cleanup.3. In the Drawing Cleanup - Select Objects dialog box, under Objects To Include In

Drawing Cleanup, make sure that Select All is selected. For Layers, make sure thatthere is an asterisk (*) in the box.

4. Click Next to go to the Drawing Cleanup - Select Actions dialog box, where youspecify the types of errors you want to clean up and the settings you want to use fordetecting errors.

5. In the Drawing Cleanup - Select Actions dialog box, right-click in the Selected Actionslist and choose Remove All.

6. In the Cleanup Actions list, select Break Crossing Objects. Press CTRL and click ZeroLength Objects, and then click Add to add them to the Selected Actions list.

Neither of these actions requires a Tolerance value.

7. Under Options, clear the Interactive check box.

With the Interactive check box cleared, Autodesk Map corrects errors automaticallyinstead of having you review them first.

10/44

8. Click Finish to perform the drawing cleanup.

Autodesk Map analyzes and examines the map and reports on the command line that itmodified 1 object.

9. From the File menu, choose Close.

10. When you are prompted to save the drawing, click No.

Now you know how to set clean up options to detect map errors and have AutodeskMap correct them automatically. In the next exercise, you learn how to simplifycomplex maps.

Exercise 3: Simplify a Complex Map

In this exercise, you simplify a map of New Zealand, which has a complex coastline.Simplifying a map is also known as generalizing or weeding.

When you simplify objects, you reduce the number of vertices on complex lines and eliminateunnecessary complexity. The resulting map has a smaller file size and can be plottedeffectively on a smaller page.

Note: We recommend that you run Simplify Objects as a separate drawing cleanup process(by itself), as demonstrated in this exercise. If you perform Simplify Objects with othercleanup actions, Autodesk Map automatically performs Simplify Objects first, regardless ofthe cleanup order specified.

1. From the File menu, choose Open. Navigate to your MapTut\Tutorial II folder andopen NZ-LL84.dwg.

2. From the View menu, choose Zoom > Extents to view the entire map of New Zealand.3. From the Map menu, choose Tools > Drawing Cleanup.4. In the Drawing Cleanup - Select Objects dialog box, under Objects To Include In

Drawing Cleanup, make sure that Select All is selected. For Layers, verify that there isan asterisk (*) in the box.

With these options specified, Autodesk Map considers all geometry in the map forcleanup. Note that Autodesk Map does not consider objects on layers that are frozen,locked, or OFF.

5. Click Next to go to the Drawing Cleanup - Select Actions dialog box.6. In the Drawing Cleanup - Select Actions dialog box, click Simplify Objects in the

Cleanup Actions list and then click Add. Simplify Objects appears in the SelectedActions list, indicating that it will be performed on the map.

7. In the Selected Actions list, click Simplify Objects, and type 0.1 for the Tolerance.8. Select the Create Arcs check box to allow Autodesk Map to introduce arcs into objects

when simplifying them.9. Under Options, make sure the Interactive check box is cleared to indicate that you

want Autodesk Map to make changes automatically, and then click Next.10. In the Drawing Cleanup - Cleanup Methods dialog box, under Cleanup Method, make

sure Modify Original Objects is selected, and clear all the check box options.

10


11/44

11. Click Finish to simply the map.

In the map, you can see that the Simplify Objects process reduced the number ofvertices on complex lines and created a smoother profile. On the command line,Autodesk Map reports how many objects were modified. If you want to compare thesimplified map to the original, you can undo the cleanup operation by choosing Edit >

Undo from the menu bar.

12. From the File menu, choose Close. When you are prompted to save the drawing, clickNo.

Tutorial 3: Working with Multiple Maps

This tutorial shows you how to work with multiple maps or source drawings. Source drawings,attached to a project, contain data you want to use. You use queries to retrieve objects fromsource drawings and place them in the project drawing.

This tutorial has three lessons.

Lesson 1: Defining and Using a Querying

To adjust the source drawing view

1. From the File menu, choose Open to open the sample drawing file that has two source

drawings already attached.2. Navigate to the MapTut \ TUTORIAL III directory in the folder where you installed

Map and open the MAPTUT2 drawing.Objects in the drawing will not be visible yet.

3. Type PDMODE at the command prompt. Press the Enter key. For new value, type 3.Press the Enter key again.This will make objects in the drawing clearer. The objects will appear in the next step.

4. To view the the contents of the source drawing, from the Map menu, choose Drawings> Quick View Drawings.The Quick View Drawings dialog box is displayed.

5. In the Quick View Drawings dialog box, be sure that CITYMAP1 is selected. Make

sure that the Zoom to the Extents of Selected Drawings check box is selected, thenclick OK.Rather than opening the drawing, Quick View will display the contents of the drawingwithout creating any objects.

6. At the command prompt, type REGEN, then press the Enter key.The REGEN command will clear the screen after using Quick View.

Now you know how to zoom a project to the extents of a source drawing, and how touse Quick View to view the source drawing.

Tutorial 5: Using Topology for Spatial Analysis (Utilizarea topologiei pentru analiza

spatiala)

You can create topology with Autodesk Map to add information to your data and to facilitateanalysis. Topology defines the relationship between adjacent objects and groups of objects,and stores the information as object data.

Lesson 1: Creating a Network Topology

Network topology uses the interconnections of lines (links) to form a linear network. Whenyou create a network topology, information about the links and their relationships is stored asobject data on each link.

To create a network topology

In this lesson, you create a network topology from lines and polylines that represent streets.Autodesk Map places a node (a point object or block) at the intersection and end of each link(line).

1. From the File menu, choose Open. Navigate to your MapTut\Tutorial V folder. Openhouses5.dwg.

2. From the Map menu, choose Topology > Create.3. In the Create Polygon Topology - Select Topology Type dialog box, click Network For

9. For Point Object For Node Creation, leave the setting as ACAD_POINT to create newnodes as points.

10. Click Finish.

Autodesk Map creates the network topology and reports on the command line that itwas successful.

The map doesn't look any different, but Autodesk Map has added data to each link andnode that make up the topology. The data contains information about the relationshipsbetween the objects in the topology and information about the object. You now have a"smart" map! You can use this relationship data to perform spatial analysis or performa topology query. Autodesk Map also placed node objects at the intersections and endsof the links in the network. To better view the nodes, you can change the appearance ofthe point objects that represent the nodes objects.

11. From the Format menu, choose Point Style. The Point Style dialog box is displayed.12. In the Point Style dialog box, select the X point style. Then click OK. In the map, each

node you created appears as an X.13. Again, from the Format menu, choose Point Style. The Point Style dialog box is

19. Click OK to close the Edit Object Data dialog box.20. From the File menu, choose Close to close the drawing file. When you are prompted to


Lesson 4: Analyzing a Polygon Topology

You can use a topology you've saved to analyze areas and interactions between areas. In thislesson, you use one polygon topology showing the area affected by a pollutant spill, andanother polygon topology of housing parcels to display parcels affected by the spill.

Exercise 1: Prepare the Project Drawing for Analysis

In this exercise, you create a new drawing, attach files, and define a query. You also load an

existing polygon topology from an attached drawing and set up drawing layers to display it.

1. From the File menu, choose New. Note: If you have disabled Autodesk Map Today,you can skip Step 2.

2. In the Autodesk Map Today window, select Start From Scratch, and then click English(Feet and Inches).

3. In the Project Workspace, right-clickDrawings and choose Attach from the shortcutmenu. Using the TUT_DRIVE alias, select parcels6 from the TUTORIAL V folder.Click Add, then click OK. If your TUT_DRIVE alias is not set up properly, see theCreate a Drive Alias lesson of the Getting Started tutorial.

4. In the Project Workspace, right-click the parcels6 drawing and choose Zoom Extentsfrom the shortcut menu.

Although you may see no change yet, this step prepare your drawing for the bestvisibility as you proceed. Next, you define and run a query to bring objects from theattached drawing, parcels6.dwg, into the project drawing so that you can work withthem.

5. In the Project Workspace, right-clickCurrent Query, and choose Define from theshortcut menu. The Define Query dialog box is displayed.

6. In the Define Query dialog box, define a Location All query. Then execute the query inDraw mode. The results of the query appear in the drawing.

Lesson 5: Editing a Topology

To edit a topology, you should use the topology editing commands rather than standardcommands such as MOVE or ERASE. With standard commands, you might lose data. Even ifyou don't lose data, you would still have to create the topology again.

To edit a polygon topology

In this lesson, you edit the PARCELS topology and merge (a imbina) two parcels by removingthe link that separates them.

1. From the File menu, choose Open. Navigate to your MapTut\Tutorial V folder. Openparcels5.dwg.

2. In the Project Workspace, click the plus sign (+) next to Topologies. Right-clickPARCELS and choose Administration > Load Topology from the shortcut menu.

3. In the Autodesk Map Topology Audit dialog box, Autodesk Map reports that thetopology is correct and complete. Click OK.

Next you view the data and then edit it.

4. From the View menu, chooseNamed Views.5. In the View dialog box, select PARCEL_2015 in the list, click the Set Current button,

and then click OK. In the map, parcels with IDs 11232013 to 11232017 are clearlyvisible.

6. In the Project Workspace, right-click PARCELS and choose Merge Polygon from theshortcut menu.

7. In the map, select the boundary between parcels 11232015 and 11232016.8. Select the text for parcel 11232016.9. On the command line, type Y, and then press ENTER.

The boundary between the two parcels, and the centroid for parcel 11232016 aredeleted.

Next, you will view the object data to confirm that the topology is complete.

To view the centroid object data

10. From the Map menu, choose Object Data > Edit Object Data.11. Select the parcel ID 11232015. The dialog box shows that the topology for this

centroid consists of six links forming the boundary of the polygon. The topology is

complete.12. Click OK.13. From the File menu, choose Close to close the drawing file. When you are prompted to

save the changes you made, click No. Normally, you would save this drawing to savetopology information. You don't save here, but if you wish to, use a new name.

Tutorial 6: Using Feature Classification

This tutorial teaches you to use feature classification (caracteristica de clasificare) to organizeobjects in your drawing based on the real-world features that they represent. You'll create alibrary of standard objects, called feature classes. You can then easily create features in yourdrawing, such as roads or manholes, that automatically have all the properties and attacheddata that you've set up.

You can also easily select, modify, and export objects based on their feature class.

Lesson 1: Setting Up the Feature Definition File

In this lesson, you will create a feature definition file (fisier de definire de caracteristica). Foreach feature class that you want to define, you'll create a sample (esantion) object. Finally,you'll define each of the features, using the sample object as an example.

Important: To define features, you must have Alter Feature Class privileges. If you do nothave these privileges, skip this lesson and go on to Lesson 2. If you are unsure of yourprivileges, talk to your CAD manager. In a small organization, you may be able to use theMAPLOGIN command to log in as SUPERUSER, using the default superuser password ofSUPERUSER.

To Create a Feature Definition File (fisier de definire de caracteristica)

1. Open the Roads drawing in the Tutorial VI directory.

Note: This drawing has a layer called Roads, an object data table called Roads that hasfields (campuri) for Lanes ( benzi) (default 2), Surface (suprafata) (default paved),SpeedLimit (default 35).

2. At the command prompt, enternewdef.

33


34/44

Note: If you receive a warning that you have insufficient privileges, it means you donot have rights to create feature definitions. In a small organization, you may be able tolog in as a superuser using the default superuser password of SUPERUSER. If youwork in a large organization, talk to your CAD manager about getting Alter FeatureClass privileges.

3. In the New Feature Definition File dialog box, browse to the Autodesk Map6\MapTut\Tutorial VI directory. Enter the file name RoadSample and click Save. Thenew feature definition file is created.

To Create a Sample Feature Object (caracteristica obiect esantion)

4. If it is not already opened, open the Roads drawing in the Tutorial VI directory. TheRoadSample feature definition you created in Exercise 1 is still attached. You wantall roads to be on the Roads layer.

5. In the Layers list, select the Roads layer to make it the current layer. Now you'llcreate a sample road.

6. At the command prompt, enter pline. Select two points for the line and then press Enterto end the command. Now you'll specify that the road use a thicker line.7. Click the road to select it. Then, right-click the road and select Properties. In the

Properties window, click in the Lineweight box and select .40. You want all roads tohave object data attached to them that lists the surface type, speed limit, and number oflanes. This drawing already has an object data table with these fields, and you'll attacha record to the line.

8. From the Map menu, select Object Data > Attach/Detach Object Data. In theAttach/Detach Object Data dialog box, note that the Roads table is selected.

9. Click Attach To Objects and select the line. Press Enter to end the command. A recordfrom the Roads table is attached to the line.

You have created a sample object. You are ready to define the Road feature using thissample road as an example.

To Define a Feature Class

10. In the Project Workspace, right-clickFeature Classes and select Define Feature Class.11. When prompted to select a sample object, select the line you created in Exercise 2.

Press Enter to finish selecting objects. The Define Feature Classification dialog boxappears.

12. In the Define Feature Classification dialog box, under Feature Name, enter Road.Under Description, enter Local road. The Applies To tab specifies the types of objectsthat can be valid roads. For our feature definition, only polylines can be roads.

13. Under Object Types, select AcDbPolyLine. On the Properties List tab, select theproperties that should be assigned (alocate) to each object that will be classified as aRoad.

14. Under Available Properties, select the following properties:General:

Color, Layer, Linetype, Lineweight

34


35/44

OD: Roads:

Lanes, SpeedLimit, Surface

For each property, you set to specify a range of allowable values. When someonecreates a new object using this feature definition, Autodesk Map will check that itsproperties fall within the defined range (proprietatile sale se incadreaza in intervalul

definit). If the value of the property is not within the range, the property will be set tothe default value.

15. Select Color, and set both the default and the range to 1. This will make all roads red.

Select Layer, and set both the default and the range to Road. This will put all

roads on the Road layer.

For Linetype, you'll accept any value as valid, so you'll leave the range and

default blank (necompletat).

For Lineweight, you want to accept a limited set of lineweights. Note that

lineweights must be entered as whole numbers.

For example, to specify a lineweight of .30, enter 30.

16.

Select Lineweight.

For the range, enter 30,40,50.

For the default, enter 40.

For Lanes, you want to accept only 2 and 4.

17.

Select Lanes.

For the range, enter 2,4.


For SpeedLimit, you want to accept any value between 15 and 55. You specify acontinuous range by using square brackets (Trebuie sa specificati un interval continuuprin utilizarea parantezelor drepte).

18.

Select SpeedLimit.

In the Range field, enter [15,55].


When people in your group create a road, they will only be able to enter a speed limitwithin this range. If they classify an object that has an existing value that is outside this

35


36/44

range, the value will be set to the default value of 35. For Surface, you want to acceptPaved, Gravel, and Dirt.

19.

Select Surface.

In the Range field, enter Paved,Gravel,Dirt. For the default, enter Paved.

On the Class Settings tab, select how the feature appears in the Project Workspace, andhow to create a new feature.

20. Make sure Show Feature Class In Workspace is selected. Under Class Icon, select[ISSUE: Will there be a road-type icon.] Next you'll set the Create Method toPolyline. This means that when users create a Road feature, Autodesk Map willautomatically create the road using the PLINE command.

21. Under Create Method, select Polyline.

22. Click Save Definition to close the dialog box. Finally, you'll classify your sampleline as a Road feature.

23. In the Project Workspace under Feature Classes, right-click Road and choose ClassifyObjects.

24. Click OK in the Classify Objects dialog box. Select the line and press Enter.

You have successfully created a feature definition for a road. Now all the people inyour organization can create roads that automatically are on the correct layer, have thecorrect lineweight, and have the correct object data attached.

Lesson 2: Creating New Features

In this lesson, you will create a new road. By using feature classification to create the road, itwill automatically be on the correct layer, be the correct color, and have the appropriate objectdata attached. You will then edit the lane information associated with the new road.

To Create a Feature

1. In the Project Workspace, right-clickFeature Classes and select Attach Definition file.In the Autodesk Map 6\MapTut\Tutorial VI directory, select Tut_Sample.xml and clickOpen. Notice that the feature class Road appears in the Project Workspace underFeature Classes. Now you'll create the road.

2. In the Project Workspace, underFeature Classes, right-click Road and select CreateFeature.

Specify the points to draw a line, and click Enter to end the command. Note that thenew line is on the Roads layer, and has the appropriate linewe
