That's the infamous FreeCad topological naming issue. The names of faces/edges/vertices can change randomly when making changes to objects, and if you connected other objects to those faces/edges/vertices... you're out of luck. (which makes the second tutorial maybe a bit misleading. using its methods will quickly lead to issues with topological naming)HelloWorldXD wrote: ↑Thu Feb 20, 2020 11:44 amHello,
i have a question.
i assembled some parts with ASM4, this works by the way great (after a few try an errors)
But then i have to make a new cut in one of the assembly parts and the hole assembly fall apart.
The LCS References have changed. I have manually changed again the LCS position and the assembly refreshed correct.
Have i done something wrong? or is this a problem because of topological naming?
i think the idea behind asm4 is great Screws for example are very quick installed (quicker than in Solid Edge or Catia).
When i changed a feature that is in the part for example a extrusion length the assembly update correctly but when i make a new feature (Hole or somethink) the LCS changes.
Thanks for the help
With your hints I was able to get the animation to work:
I think an explanation of best practices on how to use master sketches would be very useful. Would you have time to write something about that ?
I'm wondering how true this is. When playing around with Assembly4, i created a simple sketch that simulated steering (basically a rectangle with 2 lines sticking out of it resembling he wheel axles). When animating that, i already ran into the topological naming issue >_<. So i'm afraid even with simple sketches it can quickly go wrong when animating :s...
