Access Methods


 Ribbon: Home tabModify panelEdit PolylineNot available on the ribbon in the current workspace.

 Toolbar: Modify II 
 Shortcut menu: Select a polyline to edit, right-click in the drawing area, and choose Polyline Edit.


Common uses for PEDIT include joining 2D polylines, converting lines and arcs into 2D polylines, and converting polylines into curves that approximate B-splines (spline-fit polylines).

List of Prompts

The following prompts are displayed.

Select polyline or [MULTIPLE]: Use an object selection method or enter m

The remaining prompts depend on whether you have selected a 2D polyline, a 3D polyline, or 3D polygon mesh.

If the selected object is a line, arc, or a spline, the following prompt is displayed:

Object selected is not a polyline.

Do you want it to turn into one? <Y>: Enter y or n, or press Enter

If you enter y, the object is converted into a single-segment 2D polyline that you can edit. You can use this operation to join lines and arcs into a polyline.

Before the selected spline is converted to a polyline, the following prompt is displayed:

Specify a precision <10>: Enter a new precision value or press Enter

The precision value determines how accurately the resulting polyline is to fit to the source spline. Valid value is an integer between 0 and 99.

NoteA high precision value may cause performance problems.

The PLINECONVERTMODE system variable determines whether the polylines are created with linear or arc segments. When the PEDITACCEPTsystem variable is set to 1, this prompt is suppressed, and the selected object is automatically converted to a polyline.

The conversion in both PEDIT and SPLINEDIT will obey the DELOBJ system variable.
