The problem with the conversion is not ACE Translator 3000, it is due to poor construction of the DWG. Please remember to fill a boundary for Gerber, the boundary must have 2 rules: 1. Closed and continuous 2. No Self-Intersections
If you wish to simplify DWG to Gerber conversions we recommend that the DWG file is cleaned before conversion. Clean means to make sure all boundaries are closed with no self-intersection.
