What's the easiest way to figure out which direction the cam eccentricity is?

[zimirken]

So my cam is too small/follower too big to have the follower right on, so I added some eccentricity. The problem is, I'm having trouble figuring out what direction it is on the cam model, and the cam's design is not making it obvious. Is there an easy way to see it? Like looking at a plane and then to the left or right or something?

Every disc cam generated by Design Accelerator in Inventor has the center axis added.  Using that axis, make a sketch on the face of the cam, project the axis and use it as a circle center.  You will easily see the eccentricity.  See attached screencast.
