We have little need for dimensions, however, because as just mentioned, the linework used in 3D doesn't need to be as accurate as the linework used by the actual builder. For example, if a drafter modified a floor plan dimension at the very last minute without adjusting the linework properly, that happens all the time, this should be of no concern to the 3D artist. So after receiving a drawing from an architect, one of the very first things we will do is remove all of the dimensions. Floor plans tend to also contain a great deal of notes, and while some of these notes may provide important reference information that would be useful further along the 3D creation process, much of what is found can be removed along with the dimensions. The idea is to remove everything from all drawings that is simply not going to prove useful in Cad.
