Difference between paper:

Problems:

What about parts with "floating" features that do not fit within connected components algorithm? Would need user input to determine parts
Use PNGs as well as DXFs
Set the size of the object based on user input (i.e. ask for dimension of single line)

Ideas:

Get pseudo wireframe of test part.

get csv of all vertices
get csv of all edges

Create a few more parts to do tests on. Fin?
