Stress misalignment

3D Design

Hello

I have a conveyor in several sections. Depending on the configuration, either the conveyor is straight or it is folded. So I have perpendicularity constraints when it is folded. The problem is that when I change this config and go back to the folded one, the constraint reloads but not in the right way.

Do you have an idea for imposing the meaning of constraint?

Hello

Can you show the stress images of each config?

Hello

This is also a problem that I have regularly and that occurs as soon as you change the orientation of an element with a value greater than 89.9...°
One of the solutions I use is to use an "Angle" constraint and add a "Reference Entity" to it in order to define the portion of the angle to be handled.

Hello

Attached is a photo representing the perpendicularity constraint. For the unfolded config I have a coincidence constraint between these same faces.

What surprises me is that the problem is only present between parts 1 and 2 of my chassis. I have the same principle of constraints between parts 2 and 3 which is not a problem.

No better than @Pierre S's solution.

The reference entity allows you to define the direction of rotation and therefore to use angle values between 0 and 360 (maybe more)

Hello

Thank you all for your help. Indeed I did the constraint replacement with angular ones. It seems more stable.
