3.1.1.1 CAAD Objects As stated by Szalapaj (2001), CAAD objects are categorized under two main headings, 2D objects and 3D objects. 2D objects include ‘lines’, ‘grids’, ‘2D symbols’ and ‘dimensions’ (Figure 3.1). Firstly, ‘a line is a one-dimensional entity whose extend is designated by length that may exist in a one, two or three dimensional space’ (Eastman, 1999, p. 179). ‘Lines’ create a basis for basic geometries and shapes, such as polylines, rectangles, polygons, circles, arcs and curves. Secondly, ‘grids’ are used to define guidelines on the drawing surface and they are especially required when forming the building construction system. Thirdly, the ‘2D symbols’ are the representations of a complex object that are used repeatedly in a drawing whether they are created by the users or imported from the object libraries. For instance, architectural ‘2D symbols’ include door, window, sink, toilet, etc. symbols. The last item in the 2D objects is ‘dimensions’ with which the accurate measurement of the lines, the angles and the distances are calculated. Figure 3.1 2D CAAD objects 29
3D objects include ‘planes’, ‘volumes’, ‘quadric surfaces’ and ‘3D symbols’ as Szalapaj (2001) mentioned (Figure 3.2). To begin with, ‘planes’ are defined with three non-collinear points that are flat and are constructed simply by creating a 2D form and extruding this form. Next, ‘volumes’ are drawn by providing parameters like length, width, height, radius to predetermined 3D volumes existing in most of the CAAD software. Some of the examples of ‘volumes’ include; blocks, spheres, hemispheres, cones and cylinders. ‘Quadric surfaces’ are generated from conic sections which are the 2D shapes formed when a plane cuts a cone at various angles. Later on, these sections are rotated 180 degree through an axis while generating a surface. Spheres, ellipsoids, hyperboloids and paraboloids are some of examples of these 3D objects (Szalapaj, 2001). Finally, ‘3D symbols’ are similar to 2D symbols and mostly created by users. While these symbols reduce the memory size of the models, each symbol can also carry additional information about their cost, size, etc (Szalapaj, 2001). Figure 3.2 3D CAAD objects 30
