Next update for Multisim, please make the default non-polar capacitor option (film, ceramic, mica) one which matches the outlines in Ultiboard. The default option seems to be a radial electrolytic -- not helpful if you are writing in a a bypass or timing cap. Last time I used a radial electrolytic was in the 1990's.
Here's why you have to fix this -- when you transfer to UB you've got a bunch of devices where the pads/holes are named with a "+" and "-" rather than "1" or "2". You can't automatically "Replace Part" with a non-electrolytic as you immediately have a DRC error! AND you get a design error with the "+" sign repeated on the device. This makes for a time consuming mess with the netlist editor.
By the way,how are you doing replacing the greek letter "mu" upon transfer to UB?
