Assembly 3 what is the correct workflow??

[czinehuba]

Hi All,

If anybody could give me some advice regarding correct assembly it would be much appreciated.

I'm trying to recreate this assembly.

So far, I've created sub assemblies with screws of all three parts (wall plate, hat and coat hanger), and then wished to insert the three sub assemblies into a main assembly and array it. Currently the hangers aren't constrain just positioned in the correct place.

Trying to constrain the second subassembly gives me error.


Traceback (most recent call last):
File "<string>", line 515, in _catch
File "/tmp/.mount_FreeCAf1YNB3/usr/Ext/freecad/asm3/solver.py", line 416, in solve
return _solve(*args,**kargs)

objName(assembly),str(e)))
RuntimeError: Failed to solve wall_plate_sub_assy#Assembly: inconsistent constraints

Hi czinehuba,
Here is my proposition:

There is a less basic solution with constraint multiplication, but I have a problem. I will seek the advice of realthunder.

Thank you very much for this tutorial, I can see where I went wrong.
