Converting PolyLines

Use the ConvertPolyLine command to convert lightweight PolyLines to heavyweight PolyLines and vice versa.

Lightweight PolyLines are optimized PolyLines compared to old-format, heavyweight PolyLines.

If you receive drawing files that originated in applications which do not support lightweight PolyLines or if you reopen legacy drawings, you may want to convert old-format PolyLines to lightweight PolyLines. On the contrary, you can convert the other way around, if you need to supply drawing files to use in applications that do not support lightweight PolyLines.

In the Properties palette, you can view the type of a selected PolyLine. It can be either PolyLine (for lightweight PolyLines), 2D PolyLine (for old-format PolyLines), or 3D PolyLine.

To convert PolyLines:

  1. Do one of the following:
    • On the ribbon, click Home > Modify > Convert PolyLine.
    • On the menu, click Modify > Entity > Convert PolyLine.
    • Type ConvertPolyLine.
  2. Specify Heavy or Light as the target format.
  3. Specify the PolyLine entities to convert and press Enter.

    Entities of other types are ignored.

    The command reports the number of converted PolyLine entities.

  Note: You cannot convert 3D PolyLines. To convert Lines or Arcs to PolyLines, use the EditPolyLine command.
