Roller following a cam profile?

[FreddyB]

I have a roller that is spring loaded against a cam. The cam is in fact a disk with numerous bites out of it such that the roller dips in and out as the disk rotates.

Is it possible to mate the roller to a specified profile so that it follows when I rotate the disk?

Look up "Make Path" in the SW help file and it has an example that looks like it might be close to what you are describing.

The "old" way of doing this if Dan's suggestion doesn't work out is to extrude a surface made of a single spline that represents the cam surface (can be all the same elements you have now, but with Fit Spline applied to create a single, uninterrupted surface). Then, make the cylindrical part tangent to this surface that represents your cam.

You'll want the Fit Spline tolerance to be fairly tight if you need high accuracy, but it works. (This also works for animations.)
