When the internal details of an object require the extensive use of hidden lines, a sectional view is typically drawn to show the interior more clearly.

TO DRAW A PROPER SECTION VIEW, REMEMBER THE FOLLOWING:

			1. A sectional view (or section) is a drawing of an object as it would appear if it was cut in half or quartered.
			2. To define the location of the imaginary sectional plane, a cutting-plane line is used. (It should be thicker (2H or H) than the visible lines)
			3. Where the cutting-plane line passes through the solid materiel, section lining is used to show the solid surface. (2H lines at 45 degrees)
			4. Full-sections are used when the cutting-plane line extends straight through the given object
			5. Half-sections are used for symmetrical objects where the details on both sides of the center line are identical.
			6. Offset sections are used when the internal details DO NOT line up on a straight line. The offset section view remains flat despite the cutting plane line being staggered to show all of the internal details.
