3.15 Irregular Objects
You can use the construction box method to draw objects that are not rectangular (Figure 3.47). Locate the points of the triangular base by offsetting a and b along the edges of the bottom of the construction box. Locate the vertex by offsetting lines OA and OB using the top of the construction box.
