I'm looking for a way to make a simple 3-D, equation driven surface. z=sin(x)+sin(y), basically.
Is this possible? If there's not an explicit tool, can anyone conceive a workaround?

Sweep a sine wave along another sine wave, using the Parallel orientation.
When you create an equation curve on a 2D sketch, it is important to make the 2D sketch fully constrained. I added a coincident constraint between the projected origin and the sine wave, and a couple of tangent constraints between the sine wave and horizontal lines. There are two user parameters that I added: length_hori and length_verti.
You should not use the default orientation for sweep since it would produce a wrong shape in this case. The parallel sweep (aka rigid sweep) will create a "summation surface" of the profile and path curves.
Changing the user parameters will update the sweep surface. Unlike the previous example, the parameter length_hori is not a multiple of PI this time.
Attached is an Inventor 2013 model.
Hope this helps,

RDyson, I wasn't able to open the file- it said your database system was newer.
Glenn, great workaround. I had tried similar, but with a solid sweep and path-driven, and it just didn't quite work the same. Very cool how the surface sweep behaves.
Thanks both. RDyson, I wouldn't mind a screenshot or two if yours was a different method.
