47.  Tutorial 1 In this tutorial, you will create the massing geometry for a five-story office building based on the shape shown in Figure 10-61. It consists of a 50’0” X 50’0” central hall that is 60’0” high. It has a 30’0” diameter cylindrical atrium with a hemispherical dome at the top level. The central hall is flanked by the right and the left wings that are 40’0” high. The entrance area is 30’0” high. Use the dimensions of the building given in the floor plan, shown in Figure 62 and the dimensions of the elevation, shown in Figure 63. The following steps are required to complete this tutorial: 1.Open a new project file, using the default template file. 2.Add levels using the Level tool.
