Which tool allows the modification of selected geometry using commands like offset and fillet?

The correct choice highlights the Press Pull tool, which is specifically designed to modify geometry in CAD software effectively. This tool allows users to extend or shrink surfaces and solids by using various commands including offset and fillet.

The offset command enables users to create parallel copies of selected edges or faces, while the fillet command rounds off corners, enhancing the design's aesthetic and functional quality. By allowing the user to manipulate existing geometry directly, the Press Pull tool streamlines the design process and maintains precision.

In contrast, the other options serve different functions that do not involve the direct modification of geometry through offset or fillet commands. For instance, Mirror replicates selected objects across a defined axis but does not alter their shape. Motion Studies analyze the movement of objects within the model rather than altering their geometry. The Dimension Tool is used for annotating the drawing and measuring distances, not for modifying the geometry itself. Overall, Press Pull is the most appropriate tool for the functions described in the question.
