Is there a way of obtaining such flatened faces from BSpline surfaces?

In the specific case of developable BSpline surfaces, I suppose there is a way.

Great tool this new feature is useful and I hope it can be expanded with more options in the future, it's like the one that exists in Rhinoceros the command UnrollSrf
I hope in future we can develop also a surfaces with zero Gaussian curvature.

See my post here https://forum.freecad.org/viewtopic.php ... ec#p582967 and the link in that post to an older topic where the two methods are shown (Chris_G flatten_face.FCMacro is now implemented as a tool in Curves WB). Note that the method with the mesh will allow you to flatten (unwrap) most faces but its precision will depend on the mesh and the type of the surface, as already noted surfaces that cannot be exactly flattened mathematical will be distorted.

Yeah I know this method with mesh I saw a tutorial by MangoJelly on Youtube, It's like the UV unwrapping with Blender.saso wrote: ↑Tue May 24, 2022 8:27 pm See my post here https://forum.freecad.org/viewtopic.php ... ec#p582967 and the link in that post to an older topic where the two methods are shown (Chris_G flatten_face.FCMacro is now implemented as a tool in Curves WB).

New feature I haven't try yet. How it supposed to do?

When the points to interpolate are on a surface (FaceSupport property), these options allow to turn around the surface between each point.
This is an experiment. I am not sure it is really useful as it is.
But it allows to make custom spirals.

Chris, I think you have to do something for the addon manager to see the latest updates...

I increased version number to 0.5
Is it good now ?
