hi, please dont make the copper areas overlap over 3 times, that will cause this issue, we will fix it at next release.

thank you very much for your response. can you explain about overlap over 3 times because I'm really confuse with it. I think I only put 1 copper area for each layer (top and bottom). Is there any online documentation about copper area and its limitation, what should don't or do, or something like that. Because of this problem, I've waste my previous order since it has 50% defect. It's my mistake because I haven't checked it first. thank you very much in advance for your help. cheers, Budi
