SolveSpace extrude limitation

I posted about examining script-based 3D CAD apps, then returing to SolveSpace:

• Scripted 3D CAD applications for Linux — February 12, 2025

previously, I have only done wire-constructions, both 2D and 3D; now learning how to do extrusions, so as to get a proper-looking 3D object. I designed the upper-swing-arm of my trike, using knowledge from the SolveSpace getting-started tutorial here:

It was OK, designed the swing arm and exported a PNG image:

Nice, but there is a problem. Notice the ends of the swing-arm; sharp corners. I was unable to get rounded corners. The extrude feature does not support it. The holes were created by punching-through circles, and I thought that the same technique could be used on the corners. But no-go. I tried triangles and arcs, but it seems that the punch-through only works for circles.

I came across some discussion; the developers are aware of this limitiation, and there is a hint that SolveSpace v4 might tackle it.

It's not a deal-breaker. For anyone interested, the SolveSpace file is here.
