4. UMBRELLA OF FOUR PANELS WITH ONE CENTRAL SUPPORT This form was used by Felix Candela in many of his projects to cover large areas such as warehouses, factories, malls, and farmers’ markets. In Revit, each panel needs to be converted into a surface; each reference line at the center is used twice to generate the surface of two adjacent panels.

5. CURVED HYPAR, SADDLE Three arcs define this form. The lower elevation of the middle arc converts this shape into a hypar. Several variations are possible, if the nine defining points are moved in plan or elevation, after this basic shape has been obtained.
