Part number to a curved surface (bolt) using Flowify

I am trying to add a part number to a curved surface like bolt. A 3D number would be perfect. Have been using 3d Text to create the part number and manually place it on the bolt.
Was reading about flowify and tried several items .
i keep getting the error “input error : not enough input”

Suggestions? Different Approach?

Just use Rotate tool in this case.
rot-03

Or place the 3D text directly
rot-04

To learn how to use Flowify, watch a few tutorials (first, you need to form a group from each party involved in the process).
