Hi, though your job is my first bid placment with Freelancer, i have over 7years experience working with AutoCAD. And as an Autodesk certified Associate Professional (AutoCAD 2010) with Mechanical Engineering degree, i have produced several machinery components (even more complex parts) during this period.
Consequently, I am confident that generating an AutoCAD file from your sketches will be no challenge. Looking at the sketch, i think it will come out good in 3-D and will like to demonstrate my competence in this regard should you select my bid.
