Use the Make Path tool to create machine design layout sketches. For example, you can model cam profiles where the tangent relation between the cam and a follower automatically transitions as the cam rotates. A path enables you to create a tangent relation between a chain of sketch entities and another sketch entity.

A path is made up of sketch entities that are coincident end-to-end, forming a single chain. Making the sketch entities into a block is advisable, but is not a prerequisite. You can edit paths in the Path Properties PropertyManager. A chain of sketch entities can belong to only one path.
Once you have created a path, all the sketch entities in the path are selected simultaneously. To select an individual sketch entity in the path, right-click and choose Select Other.
