I have multisim 9 and I draw my schematic, now how can i do the PCB.
I noticed there is a transfer of the layout for PCB, it can transfer to Ultiboard and Protel it transfer the file in the format (*.net for protel and *.ewnet for Ultiborad)
I can't open both formats, (neither in Protel nor in Ultiboard).
The files ".net" are netlist files, not complete PCB layouts. You have to do the layout yourself.
What you need to do is open the PCB editor, place the component footprints, import the .net file, and then either manually route or autoroute the tracks.
The software doesn't do the PCB for you - you need to do the work.
