What works
Everything works perfectly and is 100% functional. The installer
runs
fine and the icons show correctly in the menu. Designing schematics
works as it should and then automatically converting them into PCBs
also works. Diptrace is composed of 4 applications and they all work
well together under wine. Even printing works as expected and allows to
print out both the schematics and the PCBs and operation is fast and
smooth, nearly as fast as the native Windows version.
I would truly recommend this program for anyone who wished to design PCBs or draw their schematics on Linux.
