Blend Curve / Surface integration project
Hello,
My 20yo son @MatteoG studies software development.
He is doing a business internship at my workshop this summer.
We would like to integrate Blend Curves, and Blend Surfaces into the Surface workbench.
I have already worked on this in the Curves workbench, so I hope we can push this a step further and integrate something similar into FreeCAD Surface workbench.
I have tried to write down a rough description of the planned features below :

Re: Blend Curve / Surface integration project
Great to hear there's some developments happening in this direction. I had some interest in trying this myself, but B-Spline work in Sketcher is taking up my time. I'd like to stay in the loop though, if possible.
Re: Blend Curve / Surface integration project
Thanks. We'll try to keep the thread regularly updated.
Today, he got an empty App::Feature of BlendCurve compiling fine, and the icon to show in the Gui.
That's a good first grip for upcoming work.

Hello,
Here is an overview of the planned implementation.
Any advice or comment is welcome. I don't think we will need a BlendPoint Feature, since it is rather low level.
Also, the Gordon Surface class won't get a feature for now, because we only plan to implement the basic Gordon algorithm, while a Feature would need much more preliminary work on the curve network.
Development is located here :

Re: Blend Curve / Surface integration project
I'm not sure to know what these are, but I'd like to see "CurvedShapes" and "Curves" workbenches merged, because they are complementary:
Code: Select all
Installed mods:
* CurvedShapes 1.0.1
* Curves 0.4.1
Re: Blend Curve / Surface integration project
Their goal is to merge Curves with Surface workbench (which is present in FC main). What is the main difference between CurvedShapes and Curves that you find, and why do you believe both are needed?Zolko wrote: ↑Mon Jul 18, 2022 1:37 pmI'm not sure to know what these are, but I'd like to see "CurvedShapes" and "Curves" workbenches merged, because they are complementary:

Re: Blend Curve / Surface integration project
No, our goal is not to merge the whole Curves workbench.
We plan only to implement the BlendCurve and the BlendSurface tools, like in the attached example :

Re: Blend Curve / Surface integration project
I use the resampling of curves a lot: airfoils come as coordinates, and different airfoil families have different number of points and distributions, especially at the leading edge, therefore the resulting sweep or loft can produce undesired warped surfaces if you use raw coordinates
Re: Blend Curve / Surface integration project
What is the meaning of the arrows?
Blend point-like functionality may be useful in Sketcher. But that might require it's own implementation and doesn't appear to be relevant to the work in this thread.Chris_G wrote: ↑Mon Jul 18, 2022 1:29 pm I don't think we will need a BlendPoint Feature, since it is rather low level.
