Converting a lot of closed splines to polylines.

[james.126519]

I have a file provided by an architect for custom perforations. We plan to cut the pattern using a waterjet, but need to change all of the spline linework to closed polylines, preferably just single lines and arcs or circles. Example attached. Any suggestions on how to go about this in a relatively quick manner other than draw over them and do a lot of copy/paste work?

Not fast but less slow ...
if peditaccept=1

pedit
[enter]
[enter]

repeat for each closed shape.

For faster, make it into a repeating macro (with a leading *).

MPEDIT won't accept splines.

I took a stab at it, and it seemed to work...
I used PEDIT, <M> <selected all> <yes> <10> <close> <enter>
And it appears to have made them all closed polylines.

Is that true?

I did notice that my attached version.. the closed plines have allot of vertices.
You may want to lower that conversion number from <10> to <1>, seems to be better.
