Nope, it's not a smooth contour.

Here's a page with some explanation and a diagram of a rosette. Dunno if
that was what the OP had in mind or not.

He wants to make master patterns for a rose engine, sort of a really
fancy tracer lathe template.

CNC and a fairly gifted graphic artist, with a suitable 3D CAD program
would be the easiest. I think in tradition, these were made by copying a
master, or a section of a master was copied several times to originate
the rossete, though i have only read about the process of ornamental
turning, and have no hands on experience.

It sort of requires a tool to make a tool to make a tool, to make a
part, to make the tool part, sort of thing.

I would expect that the rosettes may have been generated via an
ornamental turning, geometric chuck in the first place, come to think
about that.
