I was a power plant steam generator expert. One of my favorite activities is 3D modeling with SolidEdge, PTC Creo or SolidWorks. About my picture... this is a Modigliani. Similar to me.. perhaps.
Manufacturing simulations (models in various formats + videos). I will gradually add 130+ videos and models of the basics, advanced machining definitions and the use of jigs and fixtures in PTC Creo 6 and 8.0.
