This face have 5 vertexes. That's make errors with many features (offset3D...).
Could you make a tool for delete the extra vertex? :roll:

Hello,

on the latest Win Version the WB does nor show up, is this a known issue? Or are there issies with the Addon-Manager?

Thanks a lot, best Regards, Seppel

Do you have any messages in the Report View? Sorry, somehow missed the middle of the post!

None of the errors from the Addon Manager would affect whether Curves loads or not -- do you have logging turned on? If so, can you take a look at the output log file and see if there is anything unusual in the initialization of Curves?

Could you please post to the Addon Manager discussion topic to try to get those AM errors resolved? It looks like some bad cache data.

Hi drmacro,
Did you ever solve the above problem on your mac. I have similar problem which I posted to this forum:
https://forum.freecadweb.org/viewtopic. ... 13#p583313
I have a feeling my system upgrade to osx Monterey might be to blame, but I do not know how to fix. Any help is appreciated.

Thank you.

Re: Curves workbench - Mixed curves tool

Post by drmacro »

Not sure if this is a bug or expected behaviour.

When I make the curves in orange and blue, the result of Mixed curve is in black. The mid section of the resulting curve is missing...

This is an expected corner case.
The mixed curve is the intersection of the 2 extruded input curves.
For the middle segment, the 2 input lines generate identical planes when extruded, so their intersection is not a defined curve, but this whole plane.
Fortunately, the MixedCurve doesn't fail, but simply ignores the missing segment, so you can fill it with a parametric line, or interpolation curve, or blendcurve.

... playing with MixedCurve I understand, there always are 3 possible combination partners.
They can be substituted by an Extrude pair and the Section tool in PartWB.
(Is it also possible to do MixedCurve with "oblique projections" - no - because of axis direction constraint ?)

Testing the above example, there are some discrepancies in the bending curves ????
