Base Circle/Arm Angle

The choice here is for either specifying the base circle radius and Toward or Away (see below) for the follower, or to specify the initial angle of the arm, at the zero position of the cam.

 

Arm Angle or Base Circle Radius

If Base Circle is chosen above, the units for th edit box will be inches, or mm.  If Arm Angle is chosen it will be as seen below.

 

Toward/Away

If Base Circle is chosen in 1, there is a choice of whether the cam is rotating toward the pivot, or away from the pivot.  In the cam picture, the cam is rotating away from the pivot.
