One thing you can definitely try is using the "find boundary" function in
Autocad. after you find boundary for all ur regions (sounds like a lot work, but
autocad will do it for u, u just need to select the regions.), u can delete ur
regions and all boundaries will be left as polylines.

hope this hleps

Hello all,

Since we are in this conversion discussion, I have a problem and was
wondering if anyone encountered this problem.

I have created some complex shapes using the concept of regions in Autocad.
When I convert the design using PGSort, all the design gets converted except
the regions. Does anyone have an idea of converting these regions into
gds/gl1 format?

Any help would be really appreciated.

Thanks,
Pavan
