This module of the three-dimensional (3-D) stability analysis/design program (3DSAD) enables the engineer to describe the geometry of the 3-D structure, to interactively plot the desired structure, and then to obtain volume, weight, and centroid information for the structure. The general ways in which geometry is described are (a) two-dimensional cross sections extended in the third dimension, (b) eight-node brick elements, and (c) clusters of planar polygonal and bicubic patches. Curved segments can be circular, elliptical, or quadratic when using blocks and cubic when using patches. Objects can be copied, translated, rotated, or reflected about an axis as well. An arbitrary clipping plane can also be passed through the geometry.
