I have used Auto Desk Inventor for 6 years and have recently started using Solidworks. I have worked on many projects that involved steel pipe fabrication, fabricated elbows, transitional pieces, flange designs, supports all that are fabricated from plate steel. (SPFA). I have also done a lot of reverse engineering for machine shop prints on mechanical parts. I currently do work for a product development company which involves a lot of plastic part designs for miscellaneous parts and assemblies. I have spent most of my working career in a machine shop and have expanded my knowledge and expertise in CAD design.
