In this course, we are going to build a calculator assembly and look at terminology and the FeatureManager layout for assemblies. We will see how the components fit together and use different types of mates define their locations. As we are working with the assembly, we can check the form, fit, and function of our assembly to identify and potential design problems. If we find errors with the models earlier in the design phase, then we can save time and money when these parts are manufactured and avoid any costly mistakes.
