The Edit vertices option of the Pedit command 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:
The Peditext command is used in 2D Editing command group of the Quad cursor menu
Editing a polyline segment using the Quad
- Move the cursor over the polyline.
If currently ON, the TIPS widget displays:
The available commands in the Quad apply to the entire polyline. - Press the Ctrl-key to switch to segment mode.
The available commands in the Quad apply to the segment under the cursor. - When the Quad cursor menu displays, do one of the following:
- Right click to execute the default Quad command.
- Move the cursor to the Quad and move to the Edit command group.
4. Select a command:
-
Add vertex: adds a vertex to the segment under the cursor. -
Add vertex at end: adds as a new vertex at the end of the polyline.
This option is only available if the cursor is on one of the endpoints of a polyline. -
Adjust Bulge: Modifies the bulge factor of the segment under the cursor. -
Delete segment: deletes the segment under the cursor. -
Stretch segment: moves the segment under the cursor. -
Stretch vertex: moves the vertex closest to the cursor.
