Why aren CAD Drawings all Done in 3D?
Blueprints traditionally got drawn as two dimensional (2D) drawings. Architects and Engineers drew in 2D because 3D was too complicated. When Computed Aided Design (CAD) became popular in the 1980s and 1990s, we assumed most drawings would now get drawn in 3D. But they don’t. Things tend to change slowly in the design and construction industry. The typical set of plans produces today don’t vary that much from plans produced generations ago. So why aren’t most projects designed in 3D? I believe most Design Professionals are proficient at producing 2D drawings, but often don’t understand the details of how contractors build buildings. As a young Design Professional working in a Design Office, I know I didn’t. So the complexity of producing 3D drawings carries the task of actually knowing how the project will be built. The level of understanding must be much higher for the draftsman. The technology works, but the learning curve for the Design Professionals is steep. On the other hand, man

- We have drawings that are available for the building in CAD (computer added drafting); can I assume they are accurate enough to measure the building?
- Should I have the building physically measured (field verified)? Aren’t the construction drawings reliable enough to calculate the square footages?
