In this section, we will explore how to apply the parallel, tangent, concentric, and lock mates. To do that, we will apply the mates that are shown in the following image. We will refer to this drawing as we apply the different mates:

To start, download the parts and the assembly file attached to this chapter. Our starting point, which is where we will apply all the mates, will be from the attached assembly file, which looks as follows:

The attached assembly file already has a few coincident mates applied to it. The procedure of applying all the standard mates is similar, so we won't go into too much detail regarding the next four mates. Next, we will apply the parallel, tangent, concentric, and lock mates.
