Re: Curves workbench
I don't manage to use Sketch On Surface in Curves Workbench.
Whatever I do - I tried the two methods on the documentation page https://wiki.freecadweb.org/Curves_SketchOnSurface
I end up with:
' Part.:LineSegment' object has no attribute 'Construction'
which sounds like a Python error. Is it possible for you to upload a minimal working example ?
Using
OS: Linux Mint 20 (X-Cinnamon/cinnamon)
Word size of FreeCAD: 64-bit
Version: 0.20.25943 (Git) AppImage
Build type: Release
Branch: master
Hash: a65464b722a846bd2999aa2fecdff1132b15b297
Python version: 3.9.7
Qt version: 5.12.9
Coin version: 4.0.0

Re: Curves workbench
Is your Curves workbench up-to-date ?
Here is an example file.

Re: Curves workbench
Hi,
Trying to round a closed curve, but as his start begin on the first discretized point, there are still a corner on the curve.
Any tricks?

Re: Curves workbench
First, you should be careful with the Distance method of the Discretize tool, because your setting (0.75mm) puts the last point pretty close to the start point.
The Number method should be preferred if possible to ensure a uniform spacing of the points.
Then, in the Approximate feature, you can use the "Start Offset" property (in the "Range" property group) to move the start point in a straight zone.
This is just a tweak, as this does not ensure smoothness at the join-point.

Re: Curves workbench
Thanks a lot, moving the start and end point works nice.
I've thank about to work with an half curve as it's symmetrical.

Re: Curves workbench
Brown Solid feature icon for a shell I guess?
Why the shell is made instead a green solid?
Maybe because some faces are reversed?

Re: Curves workbench
The feature first tries to build a shell from the input faces, then it tries to build a solid from the shell.
Here, the solid creation failed, hence the shell result.
Usually, it comes from a poor contact of the input faces.
