Hi
please check the pin number in schematic symbol and Footprint;both should be match with each other.while importing if you not get any error ;check rates net enable

 

[asa1365]

pin number is A1,A2,....and like schematic .
how do i check rates net enable?

Hi,
check did u assign the same pin configuration for footprint.if not assign it.For rates net enable select rates all icon or display----> show rats-->all.you can find pins to be connected or not in near my components

1.open your schematic,select the symbol then Right click ---->edit properties-->PCB Footprint --->paste your footprint (created footprint) and then generate netlist
2.open your board file and import it.

hi,
check the footprint name correctly.name should not match with other footprint.one again delete the netlist file and regenerate the netlist and then import it.it will work(your schematic symbol pins and footprint pin no should be match)
