Global parameters removes the ability to constrain floor edge

Hi there, 

 

I'm trying to use global parameters to reduce the amount of element moving required when the wall system in my project is changed. 

 

This is a typical example of what my context is in 3D:

I've done this by adding reference planes, which are dimensioned from gridlines with a global parameter that represent the core boundary of the primary walls on the ground floor. 

 

The core layer offset from grid will always be the same on every elevation so this method should serve me well. 

 

I have then constrained my substructure walls (which sit below the walls on ground floor and are shown below) to the reference plane, at this point everything works as expected. If I changed the global parameter value the walls all move. 

 

The issue comes when I try to constrain the floor edge to the ref plane also. In the below picture you can clearly see that the sketch line is locked to the ref planes:

But, when I finish the sketch and change the global param value, the floor (shown selected in green) does not move with the wall and the ref plane.

What makes this so confusing is that I do not get a "Remove constraints" error, it simply updates but does not move and the constraints have been automatically removed. If I edit the sketch the floor sketch lines no longer show any constraints. 

 

I am 100% locking the floor edge to the ref plane and nothing else. Even if I lock the floor edge to the wall (which is moving as expected) the floor does the same. 

 

Why are my floor edges ignoring constraints that I'm adding to them? Is this expected behaviour? 

 

I believe it's something to do with there being walls above the floor as well which means there's a relationship between these elements which is influencing the constraining relationship. 

 

Thanks in advance if anyone has any insight.

If you're trying to align or constrain a floor edge to the walls in a sketch, using the "pick walls" feature in sketch mode could be a straightforward solution.

Weird how this method words but no other more conventional ones do!

 

Thanks for the suggestion
