I would be glad to have some input on an issue I ran into recently:
Assume I added a diode in a sot23 package. The diode symbol only have two (anode and cathode) connecting pins but the package has three pads. To the two connecting pins I assign netclasses with different clearance and creepage restrictions but then there will be no netclass assigned to the third pad of the package. This generates tons of errors when running drc and I dont have full control of the clearance and creepage distances.
For the devices I create myself I can add a connecting pin for each pad in the device and then add a short unconnected net to the unconnected pads so that I can apply a netclass. This is not the correct way to do it, does anyone know if is there any other way to do this?
