What are you using to convert them? LazyCAM? You might want to tru the demo of SheetCAM and see if it does what you need. Not as cheap as LazyCAM, but it'll work.
One thing I noticed is that you need to work on your CAD skills. If the hinge is 1-1/2" x 3", then shouldn't the radius be 3/4". I drew what I think is the correct size and added it to your drawing.
