Everywhere . . . • April 1983 - present
Time served apprenticeship through to drawing office (on a drawing board) then onto CAD starting with Computervision Cadds 4x onto Cadds5, bit of CADAM to Catia V4 and then Catia V5. I've been using CAD packages since 1989 starting on a black and white screen doing wireframe models (that's what they did back then!).
