Renderworks Style vs Eyedropper

[Jim Smith]

When working on Schematic Design I like to send clients illustrations with a couple of different options,  with a sketch style applied and from a couple of points of views. I was going to try a Renderworks style, but rather than have to try & figure this out, I just used the Open GL with Eyedropper tool to get the level of sketchiness & the look I wanted. 

I may try RW styles on some other files, but in the meantime I have a few questions:

- Does the RW Style only work using with Renderworks or does it work with Open GL?

- Is there an advantage to RW Styles over using the Eyedropper?

- I seem to recall seeing a training video on the subject of RW Styles, but I don't see it on Service Select

 

Any tips on the subject would be most welcome
