Summary of the Step.
You do not need to do this step. The model will be slower to build if you do this step. We do this step to introduce you to Add Polyline, and Add Profile to the Polyline element. Note that the Profile element does not change dynamically if the shape of the 2D-Cam cam changes. Either: Jump to Step 6A1.8 if you do not need to show the Cam as a solid element. Or: Do these two commands: 1.Add Polyline to the Inner Cam-Profile 2.Add Profile to the Polyline Note: You can do Add Polyline to 2D-Cams and Gear-Pairs. |
Why add a Polyline and Profile to a Cam?
Add these elements ONLY if you need to: •Show the Cam as an MD-Solid. •Find the Mass, Center-of-Mass, and Mass Moment-of-Inertia. of the 2D-Cam E.g. If you want to balance the Cam. •Include the Cam's mass with a Force-Analysis. |
