Challenge assembling 2 step Parts.

[chrisb]

here is my first quick suggestion with draft/part

Very interesting. Slice apart was my approach as well, but it didn't work here and I assumed the geometry errors to be the cause.

Using assembly 3 we can (again) not only place it statically in one position, but also simulate angular deflection.
I have modelled just one ball, but it can be easily extended to all 6 balls (I shall leave it to you )
starting with no angular deflection of the joint and the ball in the middle of the slot:

followed by deflecting it 15deg back:

and similarly for 15 deg forward:

as constrained the assembly is left with 3 degrees of freedom - ball can be rotated around it's centre in three axis, while remaining firmly seated in the slot
and the file for your examination:

thank you again. it's good to know that it works with assembly3. but I can't understand it. could you make a video of it?

it could work with the models from bambuko and Shalmeneser

I am sorry to dissapoint , but I have neither the skill nor the time to make videos,
happy to answer any specific questions you might have, here on the forum though

no problem, I can understand that

i created a new start file with the geometry of bambuko

something doesn't work very well? when I open it in the Linkstage3 branch:

same for master branch:

this is how i saved it because the whole model is over 1mb. everything is there for the task

Did you check this yourself? It shows still errors here. It isn't even a solid, only a shell.
