Hi!
I believe the problem isn't the constraints, but the errors in the sketches.
The problem in the constrains is a consequence of that.
Also, your files are not all migrated for the same version, this cause also issues to the model.
Use Task Manager tool to migrate all the files for the actual version.
I can't find the parameter in excel to change... anyway... i think you dont need 3 stairs in the model, i would use only one and vary only the angle for the same stair, this way i will avoid the "suppress" step.
How do you control which "echelle" is active or suppressed?
Note:
"""I'll add a constraint to a part that doesn't have any and it gives me the error. """
If you have the red cross active due sick constrains, the new constrains you create will have that error message... even if they are well created... it's a odd behaviour, but it happens.
Actually these sketches have errors only because I didn't find a way to supress sketches. So for example when i'm in 1 and 3 configuration the sketch corresponding to the 2 nd configuration will show errors because th egeometry doen't exist.
I don't get what you want me to do when you tell me to use Task manager. is there an auxiliary app to inventor called task manager ? Didn't find it.
I actually prefer to use 3 stairs than suppressing all the constraints. Because the stair can sometimes be attached to an other tube when i'm in the 3 Tube configuration for example.
This is the parameter to change to move the stair.
This is the parameter to use to change the configuration
There's several problems to fix.
First, sketches can't be suppressed, so, you must find ways to deal with that to avoid the errors.
Second, the red cross is on (as you can see in my images). i couldn't not get rid of it (i tried rebuild, drag, etc, but it still on).
third, since the red cross is active (due sick constraints), you will have that odd behaviour when you create new constrains, even if they are well created, as you show in your video.
So...
I fixed both sick constrains (change them from flush to angle, i think is more stable for this case).
Fixing the sick constrains, the new ones will be ok.
Also the rotation will work ok:
SO.....
You need now to fix the sketches. A sick model (red cross) will always work bad, sooner or later.

Sorry, is "Task Scheduller" not "Task Manager".
Anyway, it's only one file that needs migration, so you can do it manually: open and save it.

For the moment I stiill have the red cross for these sketches but everything work fine despiite of that.
You can let models with the red cross activated, sooner or later the problems will grow badly, and you will conclude that you spent tons of work hours for nothing...
Every time the red cross appears, it have to be fix immediately.
Regarding the "suppress sketch" theme... well, you have to follow the operations one by one and fix it.
I would check all the model and find alternatives.
Example, don't use projected geometry from features that could be suppressed, or you will loose those references ahead in the model.
Well... i fix the model for one configuration, i was expected that you fixed for the others.
Anyway, it's all fixed now:
Tips:
Always project geometry from the main sketches, don't project the solids that can come and go, when they go, you will loose the references... obviously.
Stop creating new sketches with the same info, use existing sketches (even the main ones) to do the operations, they already exist.
The main sketches are signed in the image below.
