Step 15: In the Assemble tab choose place component. In the new window browse to the location we saved our first part, select it and place it. By deafault the first part that is placed in an assembly or weldment file is grounded. You can change that later but for this tutorial we will keep this configuration.

Step 21: This is what we should be looking at. Now Part 2 is fully constraint.
