I know it is not enough to specify a placement. Other programs simply generate random values when not enough information is provided, which is fine for many cases. I have already solved this problem using Python. As you, I do not know the C++ code because I did not program it. But in any case I thin...

I do not know the code for the attachments, but I want to ask this anyway. How hard would it be to implement an attachment that will allow to position at the center of mass of a reference geometry, while independently control the orientation by providind a line (z axis parallel to this line); a vert...

Hi. I am doing some work that extensively relies on local coordinate systems. The thing is that I find it very difficult to achieve some placements for a LCS in reference to other geometries using the attachment options provided: https://wiki.freecad.org/Part_EditAttachment Take for instance the nex...

Hello Jose, first I want to thank you ... Regards, Benny Hello Benny. Thank you for your response. Yes, I am aware of the macro for CodeAster. I have tried it but did not succeed, most likely because it is outdated, as you have noticed. I have read the macros´s code, but it was not very useful for ...

Hello.

I wanted to share the simulation of a simple "cycloidal drawing machine":



You can download the model, the workbench, several examples, and tutorials from the link in the video description...

It would be awesome if this was implemented. It seems to me something easy to program and would be useful for those of us who are developing CAE. Many CAE guis have a fixed tree structure.

Hello. I am trying to write a script to generate a FEM file for MBDyn from a mesh generated with Gmsh, using the Fem workbench. The format of the FEM file is described on page 283 of the MBDyn input file manual: https://github.com/mmorandi/MBDyn-web/raw/main/userfiles/documents/mbdyn-input-1.7.3.pdf...

After years using MBDyn, it is the firts time I spend some time reading about the licence. I just wanted to paste the next text from the MBDyn webpage, because I think it may clarify what the GPL is, for those of us who are just learning: "The MBDyn package is distributed under Version 2.1 of t...

Ok. So as far as I only communicate FreeCAD and MBDyn through input-output files, and as far as I keep MBDyn and FreeCAD as separate programs (although distributed together) it should be OK, right?

Hello. Is there a way to have part of the tree "fixed"? By this I mean, that the user is not allowed to create or delete anything like a contanier, not allowed to move things in or out, etc. Básically I only want to allow the user to select things and edit their properties, and to right-cl...
