rounding a linear_extrude
I created a polygon and used linear_extrude() to turn it into 3D. Is
there any way to round the edges of the 3D object?
Thanks
Jon
I feel like we just talked about this topic. You can of course use
minkowski() if you're patient. There is no other reasonable way to do this
in native OpenSCAD.
In BOSL2's you can use offset_sweep() to round the top/bottom edges,
possibly combined with round_corners() to round the vertical edges. If
your polygon has long edges you may also consider using rounded_prism().

You probably are correct. Each time I look for "round" or "rounding" I
never find "offset_sweep" and I don't remember to associate the two.
Thank you

I've been using polyround.scad from the Round-Anything library to do this for my steam locomotive project. You can assign a different radius to each point. The only complaint I have with it is that if the syntax is wrong, I have to sit through a couple of minutes of its complaining about bad vec3s and such...

You might like to try round_corners() from BOSL2 to round polygons. It was
inspired by the polyround library and lets you round each corner
separately, but should issue better error messages if you give it bad
input, and it has the option of continuous curvature rounding, and other
ways to specify the rounding than just radius.
The Round Anything library does also provide polyRoundExtrude() which I
think might be more what the Jon wanted. I don't know how it works. It
doesn't look like it does a real offset operation, but results look OK as
long as the offset is non-degenerate.
