Global Parameters "Constraints not satisfied" error

[emodderman]

Hello everyone,

I'm just setting up a template file and I'm trying to have some Global Parameters automatically calculate some space planning areas. It works great, for the most part, but when I change the depth of the building, the width of one of my areas says "constraints not satisfied". When I click 'remove constraints' I can see that the width calculation has worked, but won't let me keep the constraint on the dimension and so I would have to reapply the constraint every time I want to change the length of the building.

I *think* it is because it wants to move the exterior wall instead of the room separation line, but I'm not sure, and if that IS the issue, how do I fix that? I have attached a copy of the file for your perusal.

Specifics:

When I select the lower (front) exterior wall, and change the Total Length dimension on the left, my Decor Width constraint has issues.

I'm fairly new to Global Parameters, so if you see anything else I could improve on, I'd be happy to hear it!
Thanks so much!!
