Corner point
numbering
To help understand the view of an object, you may assign a number to each
of the corners. A corner point may be hidden or visible in a particular view
of the object. Hidden corner points are numbered inside the object’s outline;
visible corner points are numbered outside the outline.
Figure 6-30 shows an object with a hidden and visible numbered corner
point.
