After migrating the design from protel(Altium) to Allegro 15.2, "unconnected pins report" showed 380 pins unconnected.Actually the pins were connected,but the clines did not snap to the middle of the pins.By re-connecting the two pins and check the "snap to connect point" box, the problem was solved. But there are too many errors like that, re-connecting all the pins cost too much time.Is there a way to set up Allegro properly and solve the errors all-together?Thanks in advance.Regards,HappySniper
After doing the conversion, in Allegro run Tools > Derive Connectivity. That should snap all the endpoints to the appropriate pad/via locations.
It works! Thank you so much!HappySniper
