I had several small designs in OrCAD PCB Editor, which is really Cadence Allegro Lite, that I wanted to merge onto a single PCB. I ham-handedly exported them as subdrawings and then imported them into a single file. The Gerber output looks fine in PentaLogix ViewMate, BUT the boardhouse says there are many layers within my artwork layers that require merging. Question 1: What is a good program to merge the layers? What is a good Gerber editor that allows minor edits to artwork and allows artwork from different sources to be cut and pasted?
