Re: FreeCAD as pre-post processor for MBDyn

@mfasano and @T-Garnier I've tried the addon quickly, it's a nice start. I would recommend you provide a step-by-step example. This will allow more people to try it and give feedback or code... perhaps you'll get some important tips. I for myself find it somewhat difficult to understand even the si...

Re: FreeCAD as pre-post processor for MBDyn

I added instructions for the total joint and total pin joint in the wiki page for the asm4 branch. I will be writing a step by step instucyoins soon. I am including a pendulum with revolute hinge joints FreeCAD file and MBDyn input file generated. I am also including a pendulum with total joints Fre...

Re: FreeCAD as pre-post procesor for MBDyn

I put what I have on the asm4 branch https://github.com/mfasano727/MBDynFCwb/tree/asm4 I added the total joint and the total pin joint. I will add instructions for those soon. The commands for the axial rotation and the ramp drive caller do not work. I am working on an inline joint and a prismatic j...

Paper comparing OpenSCAD with FreeCAD

Here is a paper I came across. I don't know if it has been discussed before. It compares scripting in FreeCAD with OpenSCAD. They conclude that FreeCAD is harder to model with scripting, but added flexibility and being able to write to formats like STEP, make it the better option. https://www.ncbi.n...

Re: FreeCAD as pre-post procesor for MBDyn

I am interested to help in the development of the pre/post procesor mbdyn/freeCAD if the project is still ongoing. Did you get in contact with the mbdyn developer team? if yes, is the project "validated"? Who could I help you on the project? I am still working on it. I have created code to add the ...

Re: Homogeneize general selection and picking all across Freecad.

Would making a start for this be a good GSoC project? It may be too ambitious. That would give us almost a year to come up with some consensus of what the interface should be.

Re: FreeCAD as pre-post procesor for MBDyn

It is simple once you have an assembly4 model. There are few input fields you need to type. I only have code for revolute joints so it is very limited, but FreeCAD and MBDyn are comprehensive. I may try a 4-bar linkage as an example next. I should have instructions soon.
