I work for and architectural firm that has everything in-house, i.e. Arch. MEP, Structural, and Civil. I got a model for a project from the architect and started laying out domestic water lines. Last night the architect decided to change the finished floor heights which we copied and monitored in the MEP model. This morning I came in and opened the MEP model and see that my piping has moved with the change in level but my plumbing elbows and tees did not. I moved everything back into place but it’s no longer a connected system – delete and redraw. Anyone else run into something like this? Is this abug or maybe something I did wrong?
