Challenge assembling 2 step Parts.

Post by thomas-neemann »

I don't know how I can bring this ball into its position on the plane shown.

I see this as a challenge of the different assembly workbenches or other functions of freecad, additional wbs or macros...

what works, of course, is manual draft move, but that's not sufficient for such a high-precision part

it is also easier to remodel the sphere in the desired position. but then it's no longer a challenge.

What is? (and how was it created?)

this is how i created it. it is the level in which the balls lie. the position of the draft working plane is probably not saved in fcstd

One more question/comment, please.
Clearly assembling a single ball is not the whole story?
We are talking (looking at your second picture in particular) about a number of caged balls,
all of them in a single plane, that should be assembled as a sub-assembly,
with an angle of this plane as a dynamic value depending on the deflection of the joint?

if all the balls can be positioned at the same time with a parametric angle of the joint, that would of course be optimal. but that's probably too much work for here

Can you provide the Inner Race without geometry errors?

It's not a question of "too much work" (and probably it isn't ?)
just that the approach and solution would be different...

we could make a part A and a part B out of it
