I am trying to make a knurled texture on semi complex geometry, but have not solved how to do it.

If you are just looking for a visual representation then you should investigate textures in the appearance section.  If you want a physical diamond knurl then it will be MUCH more complex using a bunch of path-driven sweeps.  This will really bog down your computer so I recommend the visual texture option if that will serve your needs.

Hi Casey,

I would agree with what dennis has said but if you really want to physically represent the knurled texture take a look at this video below:

will hopefully get you started

Many thanks
