A blog for all things CAD tools. For Chris Johnson, CAD is in his blood. Growing up the son of an engineer and draftsman, when the industry went from pencil to mouse, his father, Bruce Johnson, was an early adapter. Bruce quickly became the head of a CAD department, where he continues to this day. Since learning CAD at 12 years old on a 16 MHz PC, he's had thousands of hours experience modeling, drafting and programming. Chris now works for a global engineering firm as a technology leader.
