Some of the most popular components on 3D Warehouse help save designers time by providing an object they want to include in their model. To help with that, the components you upload to 3D Warehouse should use their real-world measurements and dimensions. After all, in most models a 30 foot tall bathroom faucet wouldn’t quite work.

To make sure a component is the right size, use the Tape Measure () tool. For more information on measurements and scale, see Scaling Your Model or Parts of Your Model.
