Invalid 2D symbol

[Anonymous]

When I try to select a garage door I get this warning.
Polygon is degenerated, at line 919 in the 2D script of file wa_trim_us_10.gsm.

Then in the preview window I get this message.
Invalid 2D symbol. Open the library part for editing and check its 2D script for errors.

How do I fix this?

Thank you

Generally, you get this because of poor programming on the part of the object creator. The fix (short of learning GDL and fixing the object itself) is to look for a parameter that you've used that currently has a zero value, and replace it trying a value >0. This message is usually due to a 0. Based on the message you have, the zero value is probably in the trim section of the object parameters.

Usually (and I stress USUALLY) you can use a very small non-zero value and the object will once again work.
