Re: E3D tool changer ASMBL

The program would call FreeCAD in a headless way, generate and return the raw gcode for the profile. This isn't trivial but not too difficult. However, this would have a couple assumptions built into it. It is not necessarily necessary to do this without a graphical interface. The main issue for me...

E3D tool changer ASMBL

Dear developers and users of the FreeCAD machining module, We have a hybrid 3D printing machine that combines machining and 3D printing. In order to be able to make parts with good quality geometries, we would like to be able to interpose a contouring task to each new 3D printed slice. The question ...

Re: [Request] A dedicated NURBS workbench

What's one more dependency to our ever-growing list?!? :lol: :lol: :lol: :lol: :( But nevertheless, thanks for the heads up. It would be cool to see it in action as a PoC in FreeCAD I agree ! Here is a little example of code that will help you to see how it works and what are the gains : from numba...

numba jit nopython (@njit) allows to reduce process time and works quite well with numpy.

+ we definitely could us a cplusplus dev or more to translate some of these awesome python NURBS based code to speed up their execution. Edit: @JeffWitz would you be interested in making a chart comparison ? That way we can grok where each workbench is at? @Kunda1 : Sorry I am no Cpp dev. I use pyt...

Re: [Request] A dedicated NURBS workbench

All these discussions are really interesting ! There are a lot of ways to create surface from OpenCascade, I think may be it would be important to make a functional specification. May be we can work with questions ? What are the surfaces construction methods that the curves/surfaces workbench does n...

Re: About strain and Stress

@thschrader This is not an option, it is too complicated for student use, and not suitable with the simplicity if FreeCAD. It is for optional modules where it is needed to use FEM with simplicity, and the idea is to avoid Abaqus. Salome-Meca is too complex for such task. @Bernd FreeCAD 0.18, Libs: 0...

Re: fcFEM - FEA from start to finish

As you search to increase the speed of your code, I think it could be a good idea to look at this to solutions : https://pythran.readthedocs.io/en/latest/ allows you to use a subset of numpy allows vectorization and parallelization very easily. http://numba.pydata.org/numba-doc/latest/user/5minguide...
