Use top-down modeling to design a dining table to meet the aforementioned requirements.
The top-down method is used to create six parts for a dining table. The main dimensions of the parts are determined based on the drawing of the conceptual design in Fig. 2.56. As the result, Figs. 2.57 and 2.58 show the exploded and collapsed views of the assembly model, respectively. The bills of materials (BOM) table in Fig. 2.57 shows the dining table is assembled from 17 parts.
