What is the difference between "Linear Extrude" and "Revolve" in SolidWorks?

The correct answer highlights the fundamental difference in how "Linear Extrude" and "Revolve" create 3D features in SolidWorks. Linear Extrude is a process that takes a 2D sketch and extends it in a straight line to create a solid or surface. This operation occurs in a linear direction, which can be controlled in terms of both distance and direction, resulting in a straightforward extrusion of the sketched profile.

On the other hand, Revolve takes a 2D sketch and revolves it around a specified axis to create a solid or surface. This rotational motion creates shapes that are symmetrical around an axis, making it ideal for designing parts like cylinders, cones, and other curved forms.

Understanding this distinction is crucial when choosing the appropriate method for creating features in SolidWorks, as each technique is suited to different types of geometry and design requirements. This knowledge allows users to effectively plan their modeling approaches based on the desired outcomes of their designs.
