"Thanks Luc, I think I understand all your points. I haven't looked at the updated file yet, but Marika's last one seemed to solve it, which was simplifying the overall chain. Putting a point at the spindle upper and lower, and making those…"
"I’m probably a bit late (was off-line for a time), but anyhow for what it’s worth a few remarks.
I noticed in model suspentionbit1001.3dm that the lower triangle (LCA)’s pivot’s Y-axis isn’t in line with the…"
Interesting, it was missing 1 more constraint at the end of the chain, and now it seems to work as expected.
Can you look at the change I've made quickly?
I see all 'parts' have been made not hinges, joints, or…"
"Based on your revision of my file, I changed a couple of things, and it works, sort-of. The problem is the 2 universal pivots, spindle top and bottom, become disconnected. I think maybe because the spindle doesnt rotate correctly as the lower arm is…"
"Sorry I havent been as clear.
I have attached another picture, hopefully it helps.
The 3 white circled areas, are static in position, and only rotate in 1 plane.
The 2 black circled joints, top and bottom of spindle, rotate in…"
"Have to say that I'm having a hard time following what you want to do.. Any chance that you could look up a similar animation online so that we could have a look at that?
- Currently there is nothing in the IK -setup that will make the object…"
"Thanks, that's very close, but the rear node of the upper arm moves, and it needs to be stationary. When I add another point constraint to it, I lose connection of the 2 main pivots of the 'spindle'.
The spindle will rotate,…"
