I’m trying to create a footprint using StepUp and FreeCad but I think this failed because the generated sketch has not connected edges. How can I make all the edges connected?
You can check the antena object inside the step file. I use it to create a projected sketch.
complex pads need a circle somewhere that is used as the anchor pad.
Also pads_th_smd is the wrong name for generating complex pads. Check the antenna example for how to do it.
