High, again me! I did follow Andy's advice and followed 3 times the tutorial, with good results. I'm feeling more familiar now with Kicad. But.... Now I restarted with my own (of course more complex..) project. I fixed all ERC problems (result is 0 errors) and started to check for the missing airwires in the board with funny results. Let's take out one example: In the scematic there are 10 transistors BC550 (Q1-Q10). All transistors have no airwires. I let Q1-Q5 unchanged and changed only Q6-Q10 to "TO92" kicad footprint, reloaded the partslist and: ALL transistors had airwires!?!?! Now I changed Q1-Q10 back to transistors-npn-TO92 from the imported eagle-libs. Result: Q1-Q8 had airwires, Q9 and Q10 not!?!?! Very funny. I tried it with the latest 2008-version and compiled the newest 2009 stable, with the same results. At my point of view there are 2 possible reasons for this behaviour: kicad bug or a general fault with in the sch-file. Does anyone have a tip for me?? Thank you for any help! Nukem36
