Here you can download two very similar 3D models of rosettes that were modeled during the testing period of the possibilities that the Rhinoceros 3D software has to offer.

Rhino 3D

Available NURBS and BREP file formats

.stp (Standardized 3D graphic exchange file format) and .3dm (Rhinoceros software native file format)

 

Both are NURBS surface 3D models and can be imported and modified by any 3D CAD software. Drawing 3D models of such or similar rosettes is quite simple as it comes down to drawing one segment (petal), so the whole rosette is obtained through rotational copying.
