I Have 3 parts:
1) One body blocked ; this body has an axle Z is the rotation axis
2) One arm which a hole this hole is centered on the body's axis allowing only a rotation between the arm and the body, this arm has also a prismatic section in order to guide a slider
3) One slider with the same prismatic section as the arm
I've placed LCS on each part, and I've "made" the connection between regarding LCS on both parts; and that"s working fine in a static way.
But my concern is when I try to animate all that.
I've tried to change the value of angle in the connection and it's working fine.... but I was excpecting the second relationship ( the slider relationship) not to move; And it does'nt work this way; when changoing the angle of the rotation, the positionment of the slider does"t stay on the arm.
What could happen? do I need to "block" the slider on the arm and to relax it after ( because of course, I want to move the slider when I've reached the good angle in the first movement...) and if yes, how to block? But probably , my issue is maybe due to the relative positionning of the LCS which could be perturbated by the rotation... Or maybe other thing...
if you have a solution or at least an indication on what could explain this behaviour , it will be an help for me.
