Which tool locks the current position of selected components?

The tool that locks the current position of selected components is the Rigid Group. When you use the Rigid Group feature in design software, it essentially combines multiple selected components into a single entity. This means that once they are grouped, their relative positions are fixed, preventing individual components from being accidentally moved or modified; they will behave as a single unit. This is particularly useful in complex assemblies where maintaining the spatial relationships between components is crucial for the integrity of the design.

Other tools, like Section Analysis, Project, and Scale, serve different purposes. Section Analysis is typically used for viewing cross-sections of models, helping to understand the internal features without locking component positions. The Project tool is often specified for projecting geometry or elements onto other surfaces, without affecting their initial positions. Scale is for resizing objects but does not maintain fixed positions. Therefore, the Rigid Group is uniquely focused on preserving the spatial arrangement of components, which is why it is the correct choice for this question.
