Do you know your 25.4 times table? Do you know what 0.15625 of an inch is as a fraction? Neither do I – and nor should you need to.
If you use inches or millimeters (or a combination of both), watch the video below to learn how to set units, mix units, and use fractions and expressions to drive your dimensions and 3D models. Now you can find a retirement home for that aging desktop calculator and let Onshape do all the hard work!
For more detailed information on the do’s and don’ts of mixing units and expressions, see the Onshape help documentation.
