23 Symbol shown below indicates that: A. Drawing uses the third angle projection B. Drawing uses the first angle projection C. All tapers are within machining tolerance D. Drawing must not be scaled E. Only two views are used

24 To create drawing view "B" shown in figure 6 it is necessary to sketch a spline (as shown) on drawing "A" and insert which SolidWorks view type? A. Section B. Detail C. Aligned Section D. Broken-out Section E. Aligned with Model
