I want to create a hole in each end of a cylinder.

I have figured out a few ways to do this, but it seems very quirky.

Here is what I have tried.

#1...

Create a pane on the surface of the cylinder, then sketch two points on the ends of the shaft.

I can pick the end of the cylinder to locate how far the point is from the end, and I can locate one dimension how far the point is from the edge, but it will not let me select this line a second time to dimension the other point.

I can pick this line when I dimension the first point However this line will not select for the second point?  Can someone explain what is going on.

#2...

Created the plane on the surface, and attempt to convert entries to get the projection of the outside of the cylinder for the sketch.

When I attempt to do I find it extremely difficult to not select the face.  I want to select the line that is on the edge of the cylinder, but It almost alwasy picks the face.  How can I force it to ignore the face?  When I do get the line it calls it a silhouette Edge. 

Is there an easier way?
