Thanks for your question. Is this an AutoCAD specific question, or does it involve EasyGerb.
Thanks.
Simon
If possible please submit a support ticket and include specifically what type of AutoCAD customization's you're importing. AutoCAD is a very complex tool with many customization capabilities. EasyGerb is just a simple ARX app meant to perform Gerber conversions. Unfortunately this problem seems too vague to answer directly on a forum post.
