The AutoCAD floor plans are integrated with a 3D model that is drawn simultaneously. It is a quick way to visualize the massing of the project without the expense of rendering all the detail.
This kind of complexity is hard to see in a flat 2D elevation. The mullion patterns, trim, door styles etc... are added later in the design development process.
We can take off the roof and have a look inside the second floor.

We use the AutoCAD 3D model as a background to draw quick perspective sketches.
These sketches are a quick way to explorer elements of style. This is the same perspective as the previous sketch with a different style.
What if the entry is relocated? We can quickly study plan options in 3D.
