- Why is proportion important in design?
Answer: Proportion keeps the parts of a product in the right size relationship so it both functions properly (fits, balances, opens/closes) and looks right. - What tool do we use to measure real objects before designing?
Answer: A ruler or measuring tape (a vernier caliper for higher precision). - If your longest pencil is 175 mm, what internal length should you design for comfortable fit?
Answer: About 185 mm (add ~10 mm clearance). - Which Tinkercad feature helps you set exact dimensions?
Answer: The Ruler tool (with numeric dimension boxes). - True or False: Thicker walls are always better.
Answer: False. Walls must be thick enough for strength but not waste material or add unnecessary weight; 2–3 mm is a good balance for small objects. - What is “clearance” and why do we need it?
Answer: Clearance is extra space added so parts fit or move without rubbing; it prevents jamming and allows for minor measurement or manufacturing variations.
