Export to FreeCAD to add fillets (by Laurence Rochfort)
Hello all,

Is it possible to export a completed model to FreeCAD to add fillets. If so, could somebody please suggest how the best way to do so?

Many thanks

You can export wire frame or surfaces, as step files, and afaik FreeCad will import those.

Laurence,

You can absolutely do that. I had planned a video outlining exactly that a few years ago but life got in the way of me recording it.

The more I use solvespace the more I've moved away from the FreeCAD process, unless the fillets are absolutely necessary, as it becomes cumbersome quickly.

As for the process, it's outlined below. Once you've modeled the base part, export surfaces as .stp. Go to FreeCAD:

-Click new part
-Ensure you're in the part design workbench
-Click File -> import
-Select the exported .stp file
-Click "create new body"
-Then in the feature tree drag the "imported" underneath the "Body"
-Ensure that the "body" in the feature tree is active (right click "toggle active")

Now you should be able to click any of the edges and select fillet/chamfer etc. and modify as you please.

My alternative workflow has since developed into me turning on "force NURBS to triangle mesh" inside solvespace immediately when I start working and then I'll just fake in any chamfers or fillets that I need.

I hope that's all helpful and of course if you have any questions feel free to ask.

Thank you both for your replies.

Daniel, could you please expand on what you mean by faking in the fillets?

Absolutely. See the attached model. I know the corner is sharp where all 3 of the fillets intersect, you can get around that through some other modeling tricks, but you should be able to get the idea.
