I'm new to this, so I apologize for my ignorance... I looked in the library, and I see a few vertical resistors, some of which may work, but how do I replace a 'normal' resistor on the pcb with a vertical? Or, is there an easy way to replace the package used for an already-placed component? I can place NEW components just fine, but then how do I tie it into the net, and get it to work when auto-routing (and does this affect the schematic)? Thanks
