Editing polyline vertices

Command: PEDIT

The Edit vertices option of the Edit Polyline tool modifies individual polyline vertices.

When you select this option, the program switches into a special vertex editing mode and places an X on the first vertex. The X indicates the vertex you are editing. The Next and Previous options move the X to the next or previous vertex. You can edit only one vertex at a time.

When editing vertices, you can modify the polyline in the following ways:

Starting the polyline vertex editing mode

  1. Do one of the following:

  2. Click the Edit Polyline tool button () on the Modify toolbar.

  3. Choose Edit Polyline in the Modify menu.

  4. Type editpline or pedit in the command window, then press Enter.

The command bar reads: Select polyline to edit.

  1. Select the polyline.
    The command bar reads: Edit polyline: Edit vertices/Close (or Open)/Decurve/Fit/Join/Linetype-Mode/Reverse/Spline/Taper/Width/Undo/<eXit>:
    A prompt menu displays.

  2. Choose Edit vertices in the prompt menu or type E and press Enter.
    The command bar reads: Next/Previous/Angle/Break/Insert/Move/Regen/SElect/Straighten/Width/eXit/<Next>:
    The Editpline prompt menu changes:

A triangle indicates the start point of the polyline. The first vertex of the polyline is selected.

Convert a straight polyline segment into a curve

  1. Start the polyline vertex editing mode.

  2. Select the start vertex of the segment you want to convert.
    Choose Next vertex / Previous vertex  in the prompt menu to select a vertex.
    The X indicates the currently selected vertex.

  3. Choose Angle in the prompt menu or type A and press Enter.
    The prompt menu closes.
    The command bar reads: Included angle for segment (>0 is ccw, 0 is straight, <0 is cw) <current angle>:

  4. Type a new included angle for the segment and press Enter.
    The direction of an arc segment is as follows:

  5. positive angles: counter clockwise

  6. negative angle: clockwise direction

  7. 0° for straight segments

  1. Choose Exit in the prompt menu or type X and press Enter to leave the Polyline vertex editing mode.

  2. Do one of the following:

  3. Continue editing the selected polyline.

  4. Choose Exit in the prompt menu or press Enter to conclude the Edit Polyline tool.

Break a polyline into two separate polylines.

  1. Start the polyline vertex editing mode.

  2. Select the start vertex where you want to break the polyline.

    The X indicates the currently selected vertex.

  3. Choose Break in the prompt menu or type B and press Enter.

The command bar reads: Next/Previous/Select/Go/eXit/<Next>:

The prompt menu changes:

    The X indicates the currently selected vertex.

  3. Choose Move in the prompt menu or type M and press Enter.
    The command bar reads: New location for vertex.

  4. Specify the new location for the selected vertex.
    The vertex is moved.

  5. Choose Exit in the prompt menu or type X and press Enter to leave the Polyline vertex editing mode.

  6. Do one of the following:

  7. Continue editing the selected polyline.

  8. Choose Exit in the prompt menu or press Enter to conclude the Edit Polyline tool.

Delete vertices in a polyline

  1. Start the polyline vertex editing mode.

  2. Select the vertex before the first vertex you want to delete.
    Choose Next vertex / Previous vertex  in the prompt menu to select a vertex.
    The X indicates the currently selected vertex.

  3. Choose Straighten in the prompt menu or type S and press Enter.
