What is CAD (or CADD)?
There are many CAD software applications (see our links to vendors). These replicate the old drafting board as a means to draw and create designs. As CAD applications run on computers they provide a great deal more functionality than a drafting board — and a great deal more complexity. The lines and text created in CAD are vectors. This means their shapes and positions are described in mathematical terms. These vectors are stored on computer systems in CAD files.
