ASM50X/W Error - Unable to write gdx file

During the conversion process you may get an error message
"Unable to write gdx file"

This error message will show up when you have a complex boundary that has too many vertices. This can happen when you have a boundary with many arcs and the arc resolution is set to a low value.
ASM50x version 6.06 and up will not show you this error message since we have a new chopping feature which breaks complex boundaries to smaller boundaries automatically.

Solution:

Upgrade to the latest software.
