2015 X64 is the version and thanks for the advice as to the method.

As per adamw's and your suggestion, I downloaded a SW file of a head in Grabcad and what a good move that was. Even though the author of the drawing may have different design intent than the person looking at the drawing, it is still a great way to see how others go about everything (not just the bits I'm stuck on) and what is possible in general.

Thanks.
