Floors don't follow the wall (Finishing floors from room boundary)

Hi everyone,
I have already made finising floors from room boundary, but it’s not following the wall.
So it has space, if i change the wall thickness.

Do you have any idea to fix it?
Even if i make floor from wall surface, it’s meaningless, right?
Should i lock the floor boundary to wall after creating the floor?
something like that…

Thank you for your help.

Yes, you must apply a constraint (with Align function) and lock it.

This isn’t a dynamo issue but a Revit problem.

Thank you…I will try it.

By the way, why Dynamo can’t follow the wall surface?
I have no choice to fix it without hands?

Thank you.
