Want to scale a part larger than the maximum limit allowed by the F3X slider? Or perhaps you need to input exact, sub-millimeter vectors? Require scripts bypass UI boundaries to inject exact properties directly into the workspace instances.

Here is a foundational example of how a developer might implement a standard F3X or administration tool require script:
