Pattern on a surface

Does SW have the capability to create a pattern on a complicated surface?
(Feature or in a assembly)

Envision the grip of a - say a toothbrush - I need to put a semi circular
"bump" feature
patterned evenly across surface of the rubber material.

 

The types of patterns that you might guess would do this, like sketch or
table driven, actually just project everything into the XY plane or will
only accept co-planar data points. The only way I can think of that
actually works, but is a little messy is to use the new "spline on
surface" function in 2005 and then do a curve driven pattern. You may not
get the level of control you're looking for, but it might work. I made a
spherical surface body and patterned it as a body on an egg-crate type
surface.

I've put the sample part I made up on my site, www.frontiernet.net/
~mlombard, on the SW Parts page, top of the list.
