Re: Assembly 4 workbench

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...

Re: Discussion: FreeCAD is not ready for 1.0

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...

Re: FreeCAD as pre-post procesor for MBDyn

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...

Re: searching for solid objects in a document

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...

Re: searching for solid objects in a document

TypeId does not give me what I Want. When I seasrch through the file I included. I get TypeId of Part::Box for both Cube and Cube001. I want to know which Part::Box is part of a compound.

Thanks

[Solved] searching for solid objects in a document

I would like to search a document for solid objects. I don't know how to distinguish a compound and a solid object that is part of the compound and one that is not. below is a FreeCAD file with a cube and a cylinder that is fused and a cube that is separate. The code checks for ShapeType, but I don'...

Re: FreeCAD as pre-post procesor for MBDyn

@louisgag;

I emailed Zanoni using the address he has on his profile I got by selecting his name in the team list in the MBDyn web site. I did not include you.

Re: FreeCAD as pre-post procesor for MBDyn

Ok that's nice of you. Just make sure Zanoni is in the loop, otherwise you risk going on a tangent that he doesn't approve of and, as is often the case with open-source software, end up developing you own code which has nothing to do with the original one anymore. I told him you go in touch with hi...

Re: FreeCAD as pre-post procesor for MBDyn

I am interested in helping out. I don't care if you use any of my code. I think Jose is further a long anyway. I was just experimenting with storing the MBDyn inputs in scripted objects. I'm wondering if a spread sheet may be a better way to store the data. Another way is write code that reads the i...
