Hi Jack,
Sounds like you're wanting to create drawings using the ASME drafting standard instead of the ISO drafting standard. By default, ISO uses 1st angle projection (bottom view above front) and ASME uses 3rd angle projection (bottom view below front) when creating projected and section views.
Unfortunately you can't change the projection angle in existing drawings, it can only be done when creating a new drawing. When creating a new drawing, make sure the Standard property within the CREATE DRAWING dialog is set to ASME. This will also switch the available sheet sizes from A4, A3, A2, etc to A, B, C, etc.
Also, the units of the design sets the new drawing's drafting standard and units. If the design's units are metric (mm, cm, m), the new drawing's drafting standard will be ISO and its units will be millimeters. If the design's units are imperial (in, ft), the new drawing's drafting standard will be ASME and its units will be inches. However, in Preferences (General > Drawings) you can specify the drafting standard and units to force drawings to use one or the other.

Hope this helps.
