2D CAD
Usage of CAD applications in architecture hit the average architectural practice during the early 80's. From it's origin and use in engineering and industry, CAD applications inherited a work model and interface that had little in common with the normal architectural design process. The first applications of CAD in architecture are related to the production stages of the design process. Mainly by replicating the layering techniques used in drafting, CAD offered accuracy, ease for the storage and retrieval geometries and drafting automation. Consequently the input of bidimensional drawings was the expected step on CAD development, and the one that broght CAD from research labs to architectural practices. CAD drafting takes advantage in the use of symbol libraries, laters and diemnsioning, but most importantly, gives a basic data structure for the generation of 3D structures. The use of this information as part of an Internet document presents several difficulties, standard CAD applications have file formats that are not compatible with the Internet browsers, therefore the use of additional plug-ins is necessary. Other aspect to bear in mind is the image resolution and density, as part of a browser window, a 2D CAD drawing loses a high percentage of its detail, making it useless for consultation purposes. Other approach is to make the actual drawing files downloadable, from one computer to another, this technique works on internal networks, but does not offer document security over the net. |
