feature suggestion: sculpt brush along 3d curves

the current curve tool in sculpt has the issue that is is not 3D based.
ideally you want to project curves onto a mesh so you can sculpt brush along them

specifically when you already modeled the paths this would be stunning

Mudbox and 3DCoat can do that and I think this would be a perfect addition to the current 2d mask curve tool workflow.

It’s a great idea, I can think of a workaround though. In texture paint, you could use curves to paint a disp map.

for rendering thats very true but for actual 3d printing you might need a different approach sculpting might be not bad.

Yah 3d curves would be a lot more useful than 2d ones. Maybe an option to draw a 2d curve and project it onto the mesh as well? It would also be nice to have an option to fill the interior of the curve while masking instead of just tracing the outside.

Probably not exactly what you want, but in the mean time, this might help…

Perhaps try it with “Surface (3D view only) New (grease pencil) strokes are drawn in 3D-space, with their position projected onto the first visible surface.”

I would tried like Cancer said, and even with Gpencil converted into bezier i can’t get it working and i got this error:
