Fillet across multiple parts

corentin_regal

I'm building a geometry from multiple triangles and want to 3D print each triangle individually so they need to stay separate parts.
I want a fillet spawning between two parts, how can I do that ? Does not seems to be possible directly, is there a workaround ?

You can see one triangle part in yellow :


I can merge them all and then add a fillet but then I don't have individual triangle to print anymore.

Split part after completion of fillets.

Your parts, the triangles, are all identical. Design one triangle, add dummy extensions for the adjacent parts, add fillets, cut off dummy parts, assemble the pentagon of 5 trinangle instances.

Have a look at the method I used in this doc:

This simple example is something that a pattern can achieve, but my method will work on much more complicated situations.
