Single Projection Building

Building may be used with just one projection curve. In this case, the projection curve defines the central spine of the surface.

The cross-sectional shape of the surface may be defined by just one section curve, or several section curves assigned to different positions along the surface. If you have just one section curve defined, it will be used for all the cross-sections of the surface. Varying section curves are positioned along the surface by assigning them appropriate section numbers.

To build the surface, DeskArtes combines the projection curve and section curves. The section curve center points (or origins) are located on the projection curve and the section curves are rotated so that they are perpendicular to the projection curve.

If you have chosen not to define all the cross section curves, DeskArtes internally calculates the intermediate sections. The cross sections between two defined sections will be a combination of these sections so that the surface will gradually change shape or morph.

The surface is then created by stretching a ‘flexible sheet’ over this framework of curves.
