modification of the prospectus

[giro_mary]

Bye to all,
Today I have this problem, and I can't come to terms with it.
I put the photos in because I couldn't explain:
1. in fact: 2. plan in project, with the closure of the hole of the porch and the realization of a new wall perpendicular to the existing: 3. Prospect of the factual state, after entering the project walls: Why is this distorted? How can I solve this?
thanks in advance

control how the walls in the state of fact and in the state of project come.
from the inserted images you do not understand much

effectively preventing the joint the problem is resolved.
but the fact that the creation of two walls modifies me the state of fact I do not understand, I probably have some problem with the stages, so much so that if I put "filter of the phases: state of fact" and "phase: state of fact " disappears everything and I do not think it is correct.

Maybe you don't understand how revit stages work...
