Distance range and angle range will allow us to set up an acceptable range of movement. These include angular movements as well as linear movements. Common scenarios in which these mates are used are in joints where we want to restrict the angular movements of an arm. Gas springs and distance-based switches are examples in which we require the linear movement to be restricted to a specific range. The following diagram highlights an assembly as well as what we can accomplish with the distance range and angle range advanced mates. With set angle and distance ranges, we can allow the lever and switch to only move freely within that certain range:

After knowing about the distance range and angle range mates, we will cover how to apply the mates in an assembly.
