Use this dialog box to select the cleanup actions to perform and the parameters to use. Specify whether to review errors in Interactive mode or have AutoCAD Map 3D automatically correct errors.

To select cleanup actions and set options

To save Drawing Cleanup settings as a profile

Click Tools tabMap Edit panelClean Up. At the Command prompt, enter mapclean.

You can perform multiple cleanup actions simultaneously, but it is better to perform only a few at a time so you can track changes. Run the Simplify Objects and Weed Polylines actions by themselves—not with other actions.

Cleanup Actions list

Select a cleanup action and click Add to add it to the Selected Actions list.

For more information about each cleanup action, click one of the following links:

Delete Duplicates

Erase Short Objects

Break Crossing Objects

Extend Undershoots

Apparent Intersection

Snap Clustered Nodes

Dissolve Pseudo Nodes

Erase Dangling Objects

Simplify Objects

Zero-Length Objects

Weed Polylines

NoteSome cleanup actions create a new object or break an object into multiple segments (for example, when you break crossing objects or extend undershoots with the break target option). If the original object was classified, the classification information remains with only the segment that contains the start point of the original object. You must classify the other segments manually.
Add

Add selected actions to the Selected Actions list.

Remove

Remove selected actions from the Selected Actions list.

Selected Actions list

Actions are performed in the order they appear in the list. If you include Simplify Objects and Weed Polylines with other cleanup actions, AutoCAD Map 3D automatically performs Simplify and Weed first, regardless of their position.

Up arrow

Move the selected action up one position in the list.

Down arrow

Move the selected action down one position in the list.

Cleanup Parameters

Select an action in the Selected Actions list to set its parameters. Each action has its own set of parameters. Some cleanup actions have none.

Tolerance

Specify the radial search distance for locating geometric errors. Enter a value or click Pick to specify a distance in the drawing area.

For example, if you set the tolerance to 5 units, two nodes within 10 units of each other are within the tolerance and will be corrected.

Rotation

Include rotation in the Delete Duplicates calculation for Blocks, Text, or Mtext.

Z-Values

Include z-values (elevation) in the Delete Duplicates calculation.

Break Target

Break target linear objects at the intersections during the Extend Undershoots operation.

Snap To Node

For Snap Clustered Nodes, snap to an existing node.

Snap To Link

For Snap Clustered Nodes, snap to an existing link endpoint.

Create Arcs

Allow the introduction of arcs during the Simplify Objects operation.

Weeding Distance

For Weed Polylines, enter a value or click Pick to select two locations in the drawing. Weeding Factors reduce the number of points generated along 3D polylines. A larger distance and deflection angle weeds a greater number of points. The distance is measured in linear units and must be smaller than the Supplemental Distance.

Weeding Angle

For Weed Polylines, enter the deflection angle, or click Pick to select a starting point, a vertex, and an ending point in the drawing. A larger distance and deflection angle weeds a greater number of points. The angle factor is measured in angular units.

Supplemental Distance

For Weed Polylines, enter the maximum distance between vertices. If the distance between vertices on a contour is greater, points are added along the contour at equal intervals that are less than or equal to the Supplemental Distance. The smaller the distance, the greater the number of supplemented points.

Bulge

For Weed Polylines, enter a value, or click Pick to specify it in the drawing. Bulge adds vertices to a polyline curve, creating an approximation of the curve using straight line segments. Bulge is a ratio of the distance from the arc to the chord divided by half the length of the chord.

Options

Interactive

Review errors and decide how to handle them. For example, you can correct the errors, place marker blocks on them, or ignore them.

Automatic

Have AutoCAD Map 3D correct errors automatically. AutoCAD Map 3D corrects Simplify Objects and Weed Polylines errors automatically, no matter what you specify.

Other

Load

Load a profile file that contains drawing cleanup settings you saved previously.

Save

Save your drawing cleanup settings in a profile file for later use.

Next

Move to the next drawing cleanup page.

Displays the Cleanup Methods page.

Finish

Perform the drawing cleanup operation using the current settings.
