The PocketCAD software is reported to be the first Pocket PC with fully functional CAD capabilities offered to the AEC industry. Mobile professionals can create, view, and edit CAD files directly in the field and can integrate data files between the desktop and Pocket PC using a "drag and drop" feature. The software can be used to design and plan future construction, sketch part concepts, or create snapshots of existing installations.
