I am working with a PADS .asc file of a board assembly. When I open the .asc file in circuitworks, it does not show any of the board traces, pads, vias, etc. Just the board outline and component outlines. The option buttons to select and filter traces, etc. are greyed out. The person doing the layout says they are not filtering or suppressing any features when they save the asc file. Any thoughts?
