AutoCAD 18 years (presently using version 2007) I can create you a 3D assembly from your 2D drawings using Autodesk 3D Inventor software. The 3D renderings will be accurate. I can give you your new drawings in any format you desirer. I have over 40 years experience in designing and detailing. Please review my attachments to see the guilty of my work. I will need a budget to work within to give you an updated quote. I need to work from my home as a freelancer to supplement my SS check. My name is James Scannell (Jim) a mechanical designer living in the state of Michigan, and have been a mechanical designer for over 40 years working for companies like F. Jos. Lamb, Comma and Pico.
