Yes it is.
If I had seen this 2 weeks ago, I would have tried with PythonOCC first, probably.
Thanks

No, I just did a couple of experiments, but didn't go any further.

I don't remember where I read that, but the rational coordinates in coin must be "pre-multiplied" by the weight : rational_vec = (x*w, y*w, z*w, w) import numpy as np import FreeCAD as app import FreeCADGui as gui import Part as part app.newDocument() array = np.array( [[0. , 0. , 0.01, 0.07, 0.18, ...

Thank you Chris. That is new to me. The editable interpolation curve work, blend curve not: Of course, the blend curve still needs 2 edges as input (not vertexes), but you can then set the parameters to the end of the input edges, and set the continuities to C0. Also, please not that the editable i...

I just restored it.
But I wonder why you would need it ?
The "editable interpolation curve" and the "blend curve" should both be able to create a straight segment (even though they will be degree 1 BSpline curves instead of real line segment).

Yes, you're right. At the moment we have only one of the BRepOffset classes exposed to Python but if we do more of them we should think about making packages to make it more Pythonic.

So, I suppose I should take Geom2d as model for Approximation.

Thanks to all for the help.
Ickby, I agree.
Some of the occt naming is not very meaningful.
And I don't like the AppDef name neither.
"Approximation" would be way better.

Thanks. This is very instructive and puts some light on how FreeCAD works.
I think I will stick to the FreeCAD way, and make a AppDef.h / AppDef.cpp for the pure C++ objects.

Thanks Victor,
I add another error first, but it seems to be compiling fine this way :

What error exactly are you getting with the commented-out lines in your PyImp? I get the same error as the one I get with setValue() : error: ‘PyObject {aka struct _object}’ has no member named ‘getAppDef_MultiPointConstraintPtr’ What I don't understand, is that this same function is correctly comp...
