Add the 3D-Cam


STEP 1.Click the BARREL-CAM Mechanism name-tab

You can only add the 3D-Cam in the Mechanism-Editor that has the Part for the Cam-shaft. In this example, the Mechanism-Editor is the BARREL Mechanism name-tab.

STEP 2.'Show other Mechanisms' – F11
STEP 3.Spin the View to see all the five elements for Add 3D-Cam.


STEP 4.Click the 'Add 3D-Cam' Command in the Machine-elements toolbar.
Command-Manager: 3D-Cam

Command-Manager: 3D-Cam

The Add 3D-Cam Command-Manager dialogue opens.

The 'Hint' suggests you 'Add a barrel or Globoidal cam to your model'.

The Command-Manager shows five boxes for five elements.

1r: The Cam-Follower Part

2r: The Cam-Follower Roller Profile

3r: The Barrel Part

4r*: The Barrel Blank Cross-Section sketch as a Profile*

5r*: The Barrel Blank Axis of Rotation

You MUST select the elements in order : 1 – 5



STEP 5.Click the five elements as indicated in the image, for each selection-box in the Command-Manager.

4r5r*If you want to transfer the 3D-Cam-Data to SOLIDWORKS®, the sketch should ONLY have the cross-section of the Cam-Blank as a sketch-loop, and the Cam-Blank axis of rotation, is a Line.

Delete all other sketch-elements in the Part.


MechDesigner draws the 3D-Cam as a tube. The Cam-Follower's flanks are always 'inside' the tube.  The 3D-Cam is the 'negative' of the Cam.

Use the 3D-Cam dialog-box to:

edit the design parameters to specify the 3D-Cam
save the cam as a STEP file
transfer the Data to SolidWorks®
