First of all, I can see that you have put down a lot of great work in this model!
The windows and doors are collected from BIMobjects, good.
However, it might seem like you have done a bit more than you should.
The dimension lines for instance, there are just too many. It is hard to navigate
and find the dimensions that I have to check, and actually would be on a construction drawing.
Keep it simple, with overall dim.lines and dim.lines for the inner-walls.
The construction drawing from the assignment is a good star
