Are part numbers and pad numbers in a SuperPCB part necessary?
In general part numbers and pin numbers are necessary because of the autorouter. You do not have to number pads if they are just used for mounting. The NOTEPAD text editor keeps adding a .TXT extension to my .LIB file in SuperCAD! In Windows 95, when you first use the NOTEPAD editor to create .LIB files for the BUILD utility, it adds a .TXT extension. To prevent this, click the View menu in My Computer or Windows Explorer, and then click Options.
