Threaded Hole Through Side of Cylinder

I am trying to place threaded holes around the circumferenceof a cylinder. I have been unable to do this using the hole wizardcommand.

It keeps giving me an error "Points to locate holes are not valid.They may not be constrained or may be located on edges orvertices." I am using a 3d sketch to locate the initial hole then Iwas going to do a circular pattern for the others.

The only way I have been able to get my work done is to justextrude a hole from a plane tangent and call out the threads on thedrawing. Is this a limitation of SW or am I missing something?

Thanks for any help.SolidworksParts And Features
