I am a retired product designer and manufacturing engineer. I have used Pro Engineer (PTC) for the last 25 years. I still have and operate an up to date licensed copy of Creo. I have been doing business as "Sawyer Design & Detail" (SDD) for the last 16 year. In January of 2015 I got a ultimaker original +. It is teaching me how to print. This give me something to design. I'm just an old fart trying to justify the maintains fee for proe.
