Placing a design into a stl surface

Hi guys,
so I have been trying to place my design onto the top surface in this image. I cant do flow along the surface or that kind of commends cause it is a stl file and I don’t have a fine surface. How can I do this?
Thank you from now.

in version 7, quadremesh the blue object-

then use the tosubd command and tonurbs command to get a nurbs object,

then project curves and rebuild as needed to get a nurbs patch that you can flow your object onto

OR

you can also just project curves onto the mesh, rebuild them (this is a must do) and then create a nurbs patch with edgesrf or loft that is close enough for you to use as a flow object.
