A detailed drawing can be seen here: https://ww1.microchip.com/downloads/en/DeviceDoc/ATtiny806_1606_Data_Sheet_40002029A.pdf Section 34.2 20-Pin VQFN As you can see, the pads at the corner have a non rectangular shape. I read http://pcb.geda-project.org/pcb-cvs/pcb.html#Library-Creation and there was mentioned: 10.2.1 Creating Newlib Footprints "Currently a rectangle or polygon may not be used as a pad. " Is there any chance to create a footprint for PCB for VQFN-20 as given in the above linked data sheet with non rectangular pads? Thanks Klaus
