I have just started a work bench as a pre and post processor for MBDyn. Sounds great that you had the same idea! Would you mind sharing some details? My approach has been to create customized objects in FreeCAD that contain the properties of each object required by MBDyn. Thus, I create a "Gravity"...

I have never heard of a horizontal rotating piston, and the link was not that informative. Is this a steam version fo the wankle engine?

Awsome model. I am always impressed when I visit the user showcase.

I have just started a work bench as a pre and post processor for MBDyn. I was going to use assembly 4 as a base. I thought the use of local coordinate systems would be useful and I would not need a constraint solver because MBDyn would notify if there was a problem. I also thought it would be diffic...

Hello Zolko;

Have you tested Assembly4 for with Realthunders link merge? If you do not want to build it. Maybe you can use this PPA.

Would you have the possibility to replace in that file the line 123 with:

Code: Select all

		self.oldLCS = self.partLCSlist.findItems( self.old_linkLCS, QtCore.Qt.CaseSensitive )
by
		self.oldLCS = self.partLCSlist.findItems( self.old_linkLCS, QtCore.Qt.MatchExactly )

This fixes it.

Thanks.

Running the Python command 'placeLinkCmd' failed: Traceback (most recent call last): File "C:\Users\fasa02\Documents\FreeCAD-asm3-Win64-Py3-Qt5-20190703\Mod\Mod_Asm4\placeLinkCmd.py", line 1...

hello again; I reinstalled assembly 4, and ran into the same problem that dan_liem had. You said put the WB in the mod directory of the standard Freecad; that worked for me, thanks. I am trying to make a chain of rods, and it is not working for me. When I place the rods by matching the coordinate sy...

I had the same problem as dan-miel with windows 10 and found if I moved mod-asm4 directory in the mod folder of the regular Freecad distribution it shows in Realthunders branch.

Hello again; I have downloaded the latest version of assembly 4 and I am able to link parts. I tried to place the rod so it is the LCS pivot2 is attached to LCS_0 of the parent assembly the part did not get placed as I expected. Also, when I saved the assembly exited Freecad and reopened the files, ...
