HALF SECTIONS
Half Section Views are used primarily on symmetrically shaped objects (where both halves are the same). They are a great shortcut because you can depict the inside and outside of the object all in one view.
Half Section Views can be placed on the same page or on another page.
If the view is displayed on another page, the Cutting Plane and Arrows always are displayed

FULL SECTIONS
Full section views cut all the way across the object.
Full Section Views can be placed on the same page or on another page.
The Cutting Plane and Arrows always are displayed.

dimensioning includes measurement, notes, and symbols

placement of dimensions

dimensioning diameters

dimensioning radii which do not need their centers located

dimensioning radii when locating the radius center

each dimension should not be duplicated or given on a drawing in two different ways

dimensions should be placed in the view where the best shape and true form are shown

do not assume that a part is symmetrical.

line up dimensions horizontally and vertically where possible

avoidcrossing dimension lines

Guess what! Its a bridge!!!
