So I've run into a problem when using surfaces to both start and end an extrude (either cut or boss).  Say I set up two flat surfaces a distance apart and make a drawing from a seperate plane.  I then do an extrude and set the "from" to the first surface and "direction 1" up to the other surface.  I get the error "the end face cannot terminate the extruded feature".  Yet when I set either the "from" as the sketch plane or the "direction 1" as blind, it works just fine so clearly the end face can terminate the feature.  In other words, I can start from my chosen surface or end at my other chosen surface, but can't do both at the same time.  Anybody else run into this problem and have a solution?

Thanks,

Steve
