Length problem with co-linear walls

[JavierCarreraArias]

Hello, I have problems with co-linear walls and changing their length.  If I try to change the length of the wall on the left it takes as base point the middle of itself and changes the dimension of the wall on the right, which It is not supposed to... Am I missing something here?  I have tried with constraints, with pinning the wall etc. and nothing works the way it should.

Any idea? Thanks

Collinear walls tend to think that they are part of a single wall. Try to break things up with reference planes.  Locking ends of the walls to reference planes should prevent what you describe from happening.

Is this what you want? Take a look at the attached file. Drag the reference planes to see what I am talking about.

Select left wall, right click on right end grip and Disallow join. Change dimension and move it.

Or, pin the right wall and lock its length dimension. Change the left wall's dimension.
