True or False: In 3D CAD with simulation, models can be rotated on the screen to view from any desired angle.

• A. Only 2D views are possible
• B. It requires special hardware
• C. True
• D. False

Answer: (C)

Rotating the view around a 3D model is a fundamental capability in 3D CAD with simulation. The software uses a camera that you can orbit around the model, so you can inspect surfaces, features, and assemblies from any direction. This ability is essential for checking clearances, fit, and geometry from multiple viewpoints during design and analysis. You typically control it with common input devices—drag with a mouse or trackpad to rotate, scroll to zoom, and pan with another gesture or the middle mouse button. Many programs also provide a view cube or orbit tool for quick standard angles, but the core idea is you can freely change the camera orientation to view the model from any angle. Because of that, the statement is true. The other options don’t fit because 3D CAD inherently supports multiple views, standard input devices are usually enough, and you don’t need special hardware for this capability.
