Converts lightweight 2D polylines to classic, heavyweight polylines. This may be needed to make drawings compatible with certain software. |
Heavy |
Converts classic 2D polylines to lightweight ones. |
3dPoly |
Converts 3D polylines (The abbreviation for this option is 3P.) |
Select entities |
Select one or more polylines. The program ignores ineligible entities. |
The primary benefit to using this command is to reduce the drawing file size by using lightweight polyline definitions.
This command does not convert the following kinds of polylines:
- Curve-fit
- Splined polylines
- Polylines with extended object data stored on their vertices .
You may not need to use this command in the following situations:
- Editing commands apply to both classic and lightweight polylines.
- The PlineType system variable specifies whether classic polylines are converted to lightweight polylines automatically when an older drawing is opened. You can use this system variable to determine which style of polyline is created in new drawings.
