Why can't I sweep

[jakob]

I use FreeCAD 0.17 and in part design I use the sweep function.
Error message "failed to valid broken face.
I can change to part wb and the sweep works.

It is just a circle and I try to sweep it along a path.

Have you taken the time to do a forum search? You would have found countless forum topics about it. The "failed to valid broken face" message means that your profile sketch is not closed, therefore it cannot generate a face from it.

But since you say this is only a circle, then something weird is happening. As detailed in the forum rules:

5. Add your FreeCAD file and/or screen captures
Your FreeCAD file (*.FCStd) can be useful to troubleshoot the problem

Works here as expected. Could you post your file before the error to be examined?

I manage to figure it out.
First I did profile, path
then I use the sweep function the last sketch is used automatic.
And it tries to sweep the arc arround the circle.

I just changed the order and did the path first, and it worked out.

The order of sketch creation does not mater. The order of sketch usage matters. PartDesign creates a single solid. So you can not use non closed sketches to sweep, loft, pad, pocket, revolve, groove, for the profile to be swept, padded,...
