Editing polyline vertices – Bricsys Support and Help Center

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.
