Fail to export sketch to footprint

[qaqcvc]

I am trying to export a sketch to footprint. I have already successfully exported one footprint before, but with this one, it can only export one pad. Anyone knows the reason?

The freecad file is here: test.zip

@qaqcvc
you are creating some rounded rect pads using polylines...
it should work following the samples in kSU Demo folder...

PS your test FC file seems empty
