How to wipeout SPLine or arc ?

[theethawach_lekphat]

Draft equipment, 

I want wipeout boundary of equipment (Have Arc + Line + Polyline + Circle). 

Normally wipeout used with Polyline or Polygon. But equipment drawing have Arc + Line

And because it is not a polyline, do it right the first time, you can not add or remove a point afterwards... 🤔

Snap on a small number so you can select a few points on the arc and the Object snap mode with Nearest on.

And Goooo...

A wipeout allows only straight lines as a boundary. That is, you must replace the arc(s) with a series of line segments (and, of course, join all segments into a polyline).

You can do that either manually or use one of the LISPs which you can find around. (one example attached).

See the PLALS command defined in PolylineArcsToLineSegments.lsp, >here<, and that topic generally.

Any Wipeout-basis Polyline will need to be closed, so an Arc by itself won't do -- you would need to join Arcs/Lines into closed Polylines first.

If you have a closed Spline, you can just use SPLINEDIT's Polyline option, which will result in a Polyline of only line segments, which you can make into a Wipeout.
