Dr Footleg (he/him)I gave mechanisms in the Assembly workbench another try in the newly released #FreeCAD v1.1 but sadly it still completely breaks all the joints when you try to move a part in a mechanism like this. Am I missing a trick here?
Chris Huck@drfootleg I created a new model using some arbitrary dimensions for the linkage lengths. I then put it together in the Assembly workbench using just revolute joints. My assembly doesn’t break?
@chrishuck Interesting. I have the upper green triangle fixed in place and then the arm attached to the RH side of it is a crank which needs to do full rotations.
@drfootleg So, like this, then?
(Seems like a Strandbeest?)
@chrishuck Yes, it is actually the Carpentoid mechanism (similar to Strandbeest but with a flatter walking gait). That is really reassuring to see FreeCAD working with a mechanism like this. I will try to diagnose why my assembly built in v1.0 misbehaves so badly.
Stephen Bannasch (316 ppm)That is very cool!
I have not used Assembly and would seriously enjoy a video watching how you put this together. In general I don’t find videos useful but for tools like FreeCAD I find them very helpful.
