Summary of the Step.
Note: You do not need to do this step to get Cam-Coordinates.
Add a Polyline and a Profile to the Cam-Track of Cam 1 and show it as a Solid.
A Polyline is a sketch-element that is a copy of the 2D-Cam.
If the 2D-Cam changes its shape, you must update the Polyline.
Why add a Polyline and Profile to a Cam?
Only if you want to:
•Show the Cam as a Solid to check for collisions.
•Find its Mass Properties: Mass, center-of-Mass, and Moment-of-Inertia. e.g. if you want to balance the Cam.
•Include the Mass of the Cam with a Force Analysis.
