What is an offset and how is it used?

• A. To align two parts flush with each other
• B. To rotate one part around another
• C. To allow gap between parts
• D. To constrain two parts without making them flush

Answer: (D)

An offset means keeping two features a defined distance apart rather than touching. This creates a controlled gap between parts, which is essential for clearance, avoiding interference, and allowing movement or proper fit in an assembly. In CAD terms, an offset constraint fixes how far apart surfaces or features must be, so the parts stay positioned without becoming flush. It’s specifically about maintaining that set separation, not about rotating parts or simply leaving an unstructured gap. That’s why the option describing constraining two parts without making them flush best captures how offset is used.
