Editing polyline
vertices
Commands: PEDIT and PEDITEXT
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.
- 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.
