I am pretty new to Rhino and coming from Fusion 360, where I mostly used the solid tools. Currently using Rhino 8 for Windows.
I am attempting to make more detailed fishing lures (adding scales/patterns). I have gone down the path of heightmaps (both in Rhino and in Grasshopper) and get stuck once I have a mesh getting it to connect back to my original surface. Let me walk through my process.
- Draw a closed curve that is the side view of the lure.
- Make a planer surface
- ISO trim that surface because I don’t want the pattern over the entire area. (see attached pic for a better explanation)
- Apply heightmap to the trimmed surface
- get it looking like I want
- export render mesh
- ??? at this point I have a mesh with jagged edges and a nurbs surface. I think I would like to connect them back together, then I mirror, draw a curve connecting them and Sweep2 to connect the sides back together. This is how I made the lure pictured, minus the heightmap of course. What is the correct/better workflow to achieve what I am trying to do?
I have also tried to use flow along surface but then I end up in a hell of 100s of objects trying to union together.
I would prefer my output to be a nurbs body (output to STEP for manufacturing) but would work with a mesh output for 3D printing.
Any pointers greatly appreciated!
