Final answer:
The Section Analysis command in CAD software can add or remove 3D geometry from a model.
Step-by-step explanation:
The Section Analysis command will often add or remove 3D geometry from the model. This command is typically used in computer-aided design (CAD) software, allowing users to analyze and manipulate specific sections of a 3D model. For example, if you want to analyze the interior structure of a building, you can use the Section Analysis command to slice through the model and examine the details in a particular section.
