I am modelling a coronary stent.  I have a sketch of the flat pattern and an extruded hollow clyinder.  I want to wrap/emboss the sketch along the inside of the cylinder.  Whenever I use the wrap feature, I can see a preview of the wrap but then get the part of the feature failed to cut the body error.  Is there a way to fix this?  I've attached a copy of the file.  I've also attached a copy of another stent I have modelled so that you have an idea about what I am doing.
