Hello,
I need to modify Gerber files. I just found DipTrace. I tried the free version and it worked great except for the following issue. Some Gerber files define negative layers. For example, I have three "top copper" layers. By looks, one of them is a copper plane. The other is negative relative to this plane to create areas free of copper. The 3rd appears to be a solder paste layer. I verified this functionality of the layers in a different Gerber viewer, that doesn't have editing capabilities. Unfortunately, the Gerber import tool in DipTrace doesn't provide a choice for a negative layer. If I port the copper layer and the negative layer as "top", they get merged. I really like the editing abilities of DipTrace, but am stuck at the layer import step. Could someone help me to solve this issue.
Thanks.
Importing Gerber files with negative layers
Re: Importing Gerber files with negative layers
DipTrace doesn't support multi-layer gerber files with negative layer. We will consider improving Gerber import in future but it is not easy to integrate negative layers in DipTrace.
