Vase in Salome-Platform

Here is my model of a vase.
1) Use operation "revolution" to make vase.
2) Make curved surface in order to create the spiral. (Surface should go through the vase.)
3) Use operation "thickness" to make the surface a solid.
4) Apply operation "partition" using the curved solid as tool.
5) Explode the partition into solids.
6) Select the curve and use operation "scale" to lengthen it. (You can also explode the curve into faces, fuse the surface faces, and extrude them to achieve the same result.)
7) Use operation "multi-translate" to copy the curve around the vase.
8) Use operation "cut" to create final shape.
The model was built in millimeters, but STEP understands only meters. The model was scaled by 0.001 to convert into meters.
