My primary goal is to check the limits of movements on mechanical moving pieces (to ensure there is no collision/obstructions while they move.
My understanding of this, is that I can set "3D constraints" between elements, and after that, use their values to play.
In the following youtube video, I recorded my tries to make an angular constraint, of two rotational elements (imagine a clock).
(The video is unlisted, so it does not hurt BricSys, which is not my goal)
As you might see, it is (or it seems) impossible to create a constraints on the Z axis ( simple cylinder inside another cylinder) which is the simplest of the mechanisms.
Anybody experienced this and know how to achieve valid results?
