2D-Cam
See also: 2D-Cam dialog
We calculate for you the shape of a from the relative motions of a Cam-Part and a Follower-Part, together with the shape of the Follower-Profile.
Add the Cam-Part, Follower-Part, and Follower-Profile to the model before you do .

Prepare to add 2D-Cam (typical):
 Preparation for Add 2D-Cam
|
The elements you need in the model before you can do :
Cam-Part - any Part that is kinematically-defined
Follower-Part - any other Part that is kinematically-defined
Follower-Profile - a Profile in the Follower-Part
The Cam-Part usually moves, but it may be stationary.
The Follower-Part usually moves, but it may be stationary.
The Cam-Part and the Follower-Part must move relative to each other.
The Cam-Part and Follower-Part are usually in different kinematic-chains, but they may be in the same kinematic-chain.

Do Add 2D-Cam:
 Command-Manager: Add 2D-Cam
|
STEP 1: Click Add 2D-Cam

|
1.
OR
1. |
The command-manager indicates you need to select two elements.
|
|
STEP 2: Select the two elements
Element 1 is the Part to which you want to add the 2D-Cam - the Cam-Part.
1.Click the Part-Outline in the graphics-area, or the Part element in the Assembly-Tree
Element 2 is the Follower-Profile in the Follower-Part.
2.Click the in the graphics-area, or the Profile element in the Assembly-Tree |
Typically, the Follower-Profile is a Follower-Roller or a Flat-Faced Follower.
|
|
STEP 3: Complete the Command
3.Click in the Command-Manager. |
It may be necessary to do Rebuild Now - see

Result :
Assembly-Tree

The icon for the 2D-Cam element in the Assembly-Tree may warn you that it is a “Bad Cam”.
We warn you that a 2D-Cam is a “Bad Cam” when its minimum Radius-of-Curvature is less that than a preset percentage of the radius of the Follower-Roller. There is a default percentage and a percentage for each 2D-Cam - you can edit both.
Default Percentage - see Application-Settings
Percentage for a - see 2D-Cam dialog > Cam Range and Radius
YOU must make sure the cam is suitable for your needs, even if it is a “Good Cam”.
