Revit keep changing other wall dimension without my permission

[bourgaud.jimmy]

Hello, I'm trying to connect 2 walls but one is shorter than the other resulting in a non-90° angle. When I try to do that Revit changes the length of one of those 2 walls and if I lock them it says that it cannot respect those contraints. What can I do to connect my 2 walls respecting those contraints please?

To which wall are you referring?

I'm trying to connect the right vertical wall to the left vertical well.

I'm confused as well. Have you tried using the Align Tool? Align wall faces and Lock 'em together.

As I understand:

You have two vertical wall which you want to connect (with another wall?)

But the two vertical walls are different lengths and you want the connecting wall @ 90deg.

That is not possible.

Unless your are after something else, you are going to have to explain more.

I want to do this (see attached file) but keeping the dimension of my initial post. It keeps changing 14.60m into something else and/or 7.90m into something else and/or 2.00m  into something else and if I lock those length it says it cannot respect my constraints.

Can you not just draw an angled section of wall, from the end of the long wall to the end of the short wall?

no reason for any other wall length to change.

I think automatic joining is preventing you from doing what you want to do. Disable automatic joining by right-clicking on the blue dot at the end of both walls and selecting Disallow Join.  You can use the Join tool instead, to remove the overlapping edges and cleanup the intersection between the two walls.

I'll try this on monday since it's the week end.
