Practical Preview

Here is a preview of the Test 3 Model. This is an assembly of four parts. You will model two (similar to the drawing below), and two STEP files will be provided. Your assignment will be to model the base and arm and then construct an assembly of all four parts.

The files below are the hardware you will need to complete TEST 3. They may or may not fit the preview assembly, but you can use them to practice importing STEP files.
