Which command is useful for creating simple piping, wire springs, or grooves?

The command that is particularly useful for creating simple piping, wire springs, or grooves is the Tube command. This command specializes in generating hollow or solid cylindrical shapes, making it ideal for applications like piping, where you need to replicate a tubular structure.

When using the Tube command, you can define the path along which the tube will be created, and adjust parameters like diameter and thickness, which is essential for creating accurate representations of piping systems or springs. The versatility allows for the quick generation of complex geometries with minimal effort, making it an efficient choice for designers working on projects involving tubular elements.

In contrast, while the Revolve command can be used to create solid shapes by revolving a profile around an axis, it is not specifically aimed at creating linear tube-like structures. The Sketch On Path command allows for creating profiles along a specified path, but it does not inherently generate a 3D hollow or solid tube. The Pocket command is used for cutting away material, which is not applicable for generating piping, springs, or grooves.
