SE v20 cam assembly

[BigBlock74]

Hey guys I'm new to Eng-tips.
Joined to try and find a solution to my problem with solid edge.
I have an assembly involving a double lobed cam that a simple lever is supposed to run on with a wheel and bearing.
When i try and assemble the pair as a cam assembly it keeps coming up with a error saying something about if i'm defining the cam i need to choose a full series of tangentally continuous faces, and if im choosing the follower i need to pick just one face that will run on the cam.
I'm no computer genius and i can't figure out why it won't mate the lever to the cam.

Anyone offer any help???

Welcome to the Forum BigBlock,
The cam shape has to have all edges tangential to the adjacent edges, ie no sharp corners.
If you have a sharp corner you will need to add a round.
I think it is also telling you that it doesn't matter which face you pick first - cam or follower.
