CRISTAL: Graphic Output Using the information that has been recorded, assembled, and analyzed by the three previous stages of the methodology, the complex 2-D and 3-D graphic characteristics of architectural resources can then be represented by computer aided design models and drawings. As-built drawings can be assembled and annotated with dimension strings and details that represent a complete, graphic record of the existing structure. The measured drawings also provide a foundation for the development of construction documents that can facilitate maintenance, restoration, and adaptive use projects. The generation of CADD drawings represents the final component in the integrated videographic system of architectural data acquisition, analysis, and graphic representation. Considered as a whole, the proposed videographic method reflects the effective resource recording, management, analysis, and representational advantages that the image processing technologies hold for the architecture profession. The comprehensive information base assembled by the appropriate application of these technological tools can facilitate resolution of routine and cyclic maintenance, rehabilitation, and new construction issues.
