AutoCAD is built to design the way an engineer thinks-and the natural way for designers to work is to use sketches. IT's Adaptive Design function allows the designer to work with simple, intelligent 2D layouts that can become the foundation for 3D solid models of entire assemblies. Engineers can shorten design cycle times by using simple geometry to solve function before form.
