Re: Modeling Challenge
@Kunda1 does this apparatus any real-world applications?
Re: Modeling Challenge
Linkstage3, PartDesign, Assembly3, animated with a macro.
Code: Select all
# -*- coding: utf-8 -*-
import FreeCAD
import Part
import time
time.sleep(2)
doc = FreeCAD.ActiveDocument
theConstraints = [
doc.getObject('Constraint005'),
doc.getObject('Constraint007'),
doc.getObject('Constraint009')
]
for i in range(359):
for c in theConstraints:
c.Angle += 1
doc.recompute()
Gui.runCommand('asm3CmdSolve',0)
Gui.updateGui()
#time.sleep(0.05)
Gui.runCommand('asm3CmdSolve',0)
Gui.updateGui()

Re: Modeling Challenge
I didn't think so. But sometimes I get surprised
Re: Modeling Challenge
As LinkStage3/Assembly3 in part is based on SolveSpace solver, here is same design made with SolveSpace (animated with "Analyze > Step Dimesnion..."):
SolveSpace-file & instruction available here: https://www.patreon.com/posts/85092911
@obelisk79, in a real world such mechanism would be fully constrained to being lock in its initial state (if each pair of yokes on U-pipe would be connected with elastic shaft).
On all animations above (including on my) there are just *some tricks* used where start and end of this U-joints loop are not constrained to each other with the same rotation speed.
