Have used AutoCAD since release 2.17b (1986). Came on 2 5 3/4 inch floppies Taught 3D and Animation at Portland State University School of Architecture and the course was approved for Architectural Continuing Education Credits. Did animation and graphics layouts for Intel Corp (Hillsboro) for several years. Had a marketing CD released from Intel that I created and implemented. The Pentium 2 chip was released worldwide with my graphics and animation. Contracted to several companies in the Greater Portland Area doing proof-of-concept engineering animations. There's more but I'll finish it later.
