My Polygons are Degenerates!

[Anonymous]

I've been on ArchiCAD 10 for weeks. Today none of the windows in "Wood Plastic Windows" works correctly -- they all give me the error:

Polygon is degenerated. at line 910 in the 2D script of file wa_trim_us_10.gsm.

I have restarted ArchiCAD and that didn't solve it. Why would this suddenly start happening? How do I fix it?

have loaded some kind of beta library? it sounds as though the door/window macros you're using aren't as robust as the ones you've been using until this point.

alternatively, you've made some amendments to your doors/windows (like setting something to a zero width/length/height?) that the objects are disagreeing with . . .

Jay,
The macro "wa_trim_us_10.gsm" is notorious and versions of it have been
since AC 8.1. There is an article about it on the Grafisoft US technical
resources site.

Yup, that little piece of code has caused me (and my clients) lots of headaches.

The only article I can find regarding "wa_trim_US" deals with a group operations error. Do you have a link I could follow?

Guess what? Today everything works fine. Temperature? Moon phase? Sun spots?
