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...

Hello; I am trying to do multibody dynamics of an assembly4 model with the MBDyn solver. Here is the discussion of it. https://forum.freecadweb.org/viewtopic.php?f=18&t=39165&start=100 I am at the point of animating the model. I need to disable or delete the expression engine and then returning it b...

I have not come in to the discussion until now partly because I don't care that much. There is a old saying "all software is beta". Like others have said, including vocx, I would still use it no matter what it's called. For me, FreeCAD really became mature at release 0.17 Roland. Named after a man w...

I added a new branch for my MBDyn pre-processor. It is called asm4. It creates an MBDyn input file from a FreeCAD model created with assembly4. I thought it would make it easier to set up the MBDyn elements with it. I am not sure I am calculating the orientation matraces right. They work for my test...

obj.InList return a list, so the check if len(list) > 0, i'm assuming that only a "parent" object links to this object, if there are many (I don't know when it ossurs in freecad) you have to adapt your code accordingli, note that exist also a property named InListRecursive , but I haven't tested, I...
