Three-dimensional CAD software is often used to

• A. Draft detailed BOM
• B. Create 2D orthographic views
• C. Generate color schemes
• D. Detect interferences between trades

Answer: (D)

Three-dimensional CAD allows all building components to be modeled in one shared space, so you can see how systems from different trades fit together. The main benefit is detecting interferences between trades, known as clash detection. By running checks on the 3D model, you can identify where ductwork, piping, conduit, or structural elements collide or overlap, and resolve those issues before construction starts. This reduces costly field changes and rework and helps ensure everything can be installed as designed. While 3D models can generate 2D views or a bill of materials, the most important use in a multi-discipline project is identifying and preventing interferences.
