Double Projection Building

Building may also be used with two projection curves. In this case, the projection curves define the extents of the surface when viewed from that axis direction.

Just like building with single projections, double projection building can use one or several cross-sectional curves. This time however, DeskArtes combines the projection curve and section curves by locating the section curve between the projection curves, scaling them as necessary to fit.

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