It is used primarily by architects, but has tools for surveyors and mechanical, civil and construction engineers. It was initially designed as an electronic drawing board, using concepts and tools clearly related to a physical board. Caddie requires a USB dongle. or software activation. Without the dongle or activation, the program can be used as a viewer and plot station for any DWG drawings, but it can't save drawings after the 14-day evaluation has expired.
