Sculpting tools plugin for rhino **suggestions please

Hi anyone have good experience with engraving on an object?

I want to be able to wrap all my curves around the surfacing and then use it as a guide to help me carve and sculpt. I need a plugin preferably free fast.

I was also hoping that right before I go to 3d print, netfabb or some other software can take care of smoothing edges for me… any thoughts??

yep. Clayoo. :slight_smile: if free … you have to do in zbrush mini
