Constraints orientation bug when suppress/unsuppress part

[n_bonvin]

Hey everyone, 

I'm having a little issue with the constraints I place between parts and sketches.

I have different rules that supress and unsupress parts when needed, so the  constraints on these parts are recalculated or updated each time suppress or unsupress happens I think.

The issue is the following, each time this  happens it is  the  lotery of the  directions in the orientation of the constraints.  Sometimes it  is  flipped 180 degrees,  sometimes not. 

For example the two following  situations  are obtained with exactly the  same  constraints.

  

Do you have any Idea so that  this  does not  happen ? 

Thanks  in  advance  for  your help !

Hi

It's better to create constraints between faces, surfaces and workpieces.

I constrained the parts using plans that I created in the parts i'm constraining. Do you think this is the issue ?

I have no idea what you're doing based on your description alone.

here I  did  a  screencapture   of  the   issue.

So the problem  is that  the set  of  constraints can  be understood  in two directions  but  I  don't know how  to control these two  possibilities. I had  the  same  problemwith  another  part  I  tried  to  constraint  before.

Mate & flush constraints have only one direction.

There are several types of angular constraints, which allow you to define the number of factors influencing their work.

Does anyone else have an idea  on how to  solve my problem ?

Hi! I am surprised by the behavior. It should work regardless. If possible, please share the files in zip here. I would like to understand the constraint orientation issue better.

Many thanks!
