Here is a discussion of a recent effort.

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...

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 ...

there is work being done for that here.

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.

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.

I added post processing to the ASM4 branch to my code. There would not be too many changes to add the post processing to the branch that does not use Assembly4, but I like Assembly4. I fixed the problem I had with orientation matraces of the joints by switching to 2 vector instead of Euler angles de...

I would like to use the Qtimer for animation, but I can't get it to work even with this simple script. This does not work even if I just put a pass inside the while loop. I find it strange it works when in debug mode. The PrintMessages are just proof update function and the while loop are working. I...

I am trying to test Qtimer with this script. It works well in debug mode but it locks up just running it. import FreeCAD as App import FreeCADGui as Gui from PySide2 import QtCore class time(): def __init__(self): self.timer = QtCore.QTimer() self.timer.timeout.connect(self.update) self.count = 0 de...

what do you mean by " disable the expression engine " ? On all parts, or some of them ? It seems the I may not need it; the placement of the parts is updating on the view screen without recompute. It may not matter, but I would like to return it to the way it was at the end. recompute at the end re...
