Which statement is a benefit of using 3D CAD with simulation?

• A. It can create programs that can be downloaded to robots
• B. It can edit photographs and make them look more realistic
• C. It can create models that can be rotated on the screen, allowing viewing from any desired angle
• D. It can produce flat drawings that can be printed

Answer: (C)

The main idea is that interactive, flexible viewing of a 3D model is a key advantage. With 3D CAD, you can orbit or rotate the model on screen, inspect it from every direction, and see details that might be hidden from a single viewpoint. This capability makes it much easier to verify geometry, identify potential interferences, and understand how parts fit together, all before building anything. When you add simulation, you gain the added ability to test motion and physics, but the essential benefit illustrated here is being able to view the model from any angle to ensure accurate design and clear communication with teammates and stakeholders. The other statements describe activities that aren’t inherent benefits of 3D CAD with simulation—editing photos or producing flat drawings—or refer to downstream steps like generating robot programs that go beyond simply viewing and simulating the model.
