In CAD, what does "3D modeling" involve?

The process of "3D modeling" in CAD (Computer-Aided Design) specifically refers to the creation of a three-dimensional representation of a product. This involves building a digital object that has height, width, and depth, allowing for a more realistic depiction of the item as it would exist in the real world.

3D modeling enables designers to visualize the complete shape and form of a product, providing important insights into its dimensions, proportions, and potential interactions with other components. This representation can be manipulated and viewed from multiple angles, making it invaluable for design reviews and iterations. It forms the basis for further activities such as simulations and rendering, which can aid in understanding the product's functionality and appearance before physical production takes place.

In contrast, other options focus on different aspects of CAD applications, such as two-dimensional drawings, performance simulations, or animations, but they do not directly describe the fundamental process of creating a 3D model itself.
