I have just imported a dxf file into my layout file that I am trying to use as my board outline. When the outline imported to PADS it came in broken and as 2D lines. I have combined the lines to make a single shape, but I cannot change the line type to the board outline. The line type field in the properties menu is grayed out and I cannot find a way to make that field editable. Can anyone offer a suggestion on how to fix this problem?
