Cool! It is to be 3d printed, so texturing programs are not going to work. Got to be 'physical'!

I'll try that flow thing. It's like it needs a thin .15mm skin and then I can chop out panels for an overlap effect maybe. Then it needs the dreaded boolean solid again!

If I want raised profiled rails running along a couple of parts of the hull, would sweep be the way? Would they be solid at able to boolean to the hull?
