Summary of this Step

Before we can use Add 2D-Cam, we must add the Cam-Follower to a Part. We define its shape and its position in the Part with the Part-Editor. We use Add-Profile to make it a Solid.

In this Step:

1.We use the Part-Editor to edit the Part to which we want to add the Cam-Follower Roller.
2.We use the sketch-editor to add a circular shape to become the Cam-Follower Roller.
3.We add a Profile to the shape of the Cam-Follower to make it a 'Solid'.


Cam-Followers are in continuous contact with the Cam surface.

There is not a command: 'Add Cam-Follower'. You must sketch the shape and define the position of the Cam-Follower in the Part-Editor as a sketch-loop. Then add a Profile to the shape in the Mechanism-Editor.

The shape of the Cam-Follower does not need to be circular. See Cam-Follower.
