Circles on The Oblique Face
Thesecircles are plotted using a plotting view, which consists of a true size quadrant of the circle, together with a half size. quadrant on the same view (Fig. 8.6). The circles are plotted in a similar manner to isometric circles, except that measurements along the 45° axis are taken from the half size quadrant.
Alternatively, oblique circles may be plotted using true shape semicircles located on the edges of the oblique face and projecting points on the oblique circles as shown in Figure 8.6
