One issue with 2D CAD is that a specialist is required.
Two issues with 2D CAD are the necessity for a specialist to understand the drawings and the absence of a visual representation of the final result. With problems that cannot be resolved before building starts, 2D CAD is a time and resource waster. With BIM, a visual model enables collision detection, information attachment to the model, and a walkthrough of the building.
Technical drawings are made and edited in 2D drafting and drawing, as well as designs are annotated. Building inspection plans, floor plans, building permit drawings, and landscaping layouts are all created by drafters using computer-aided design (CAD) software.
