If I understand the question correctly,you are taking a photograph of the hand drawn graphic and importing it into Vcarve.If this part goes well can you clean up any blurred lines after using the trace bitmap utility and they use a single point engrave process?You may have to invent a new tool for the tool library to achieve the outcome you are seeking and a very close look at a high quality (the highest the system will allow and in 3D) will be useful.
