Design Spark PCB looks like the real deal, but a couple problems have arisen. Most of the parts I use will be downloaded from PCB parts. No problem there. Resistors at least, wil have to be created, no problem, but the Wizard doesn't recognize entries in my own PCB library, and the easier-to-use New Component Entry wants Package and Default Reference from the DS library, even though the information is overwritten (I hope) by other entries after. Why are these asked for in the first place? I am worried they may cause big problems down the line. Why not use entries from my own Schematic and PCB libraries instead of DS libraries? Thank you in advance for answering this question! R.
