What function allows you to define the travel of an under-constrained component?

The function that allows you to define the travel of an under-constrained component is to "Set Component Limits." This feature is specifically designed to restrict the movement of components within an assembly. When components are under-constrained, they may have freedom of movement that isn’t desired for the intended operation of the assembly. By setting component limits, the designer can specify the minimum and maximum allowable positions for a component, effectively controlling its range of motion.

While adding a path, using a sketch, or applying motion constraints are all valuable tools in assembly design, they do not focus solely on controlling the travel limits of components like the Set Component Limits function does. Adding a path pertains to creating a trajectory for motion, which may not necessarily limit the range of movement. Similarly, sketches are used to define shapes and profiles rather than to control component positions directly. Motion constraints involve defining relationships between components, but they do not explicitly set the limits on travel. Therefore, the capability of setting component limits is crucial for ensuring that components behave predictably within their defined parameters.
