AREA_FORM_TOP, AREA_FORM_BOTTOM, AREA_FORM_SIDE

Shows the area of faces whose normal vector points to the following directions:

top of form ( AREA_FORM_TOP )
bottom of form ( AREA_FORM_BOTTOM )
form sides ( AREA_FORM_SIDE )

For assemblies and cast units, the main part local up direction dictates the form up/bottom/sides directions. Faces which are inclined less than 5 degrees are counted in the top and bottom areas. Faces which are skew => 85 degrees are counted in the side areas. Faces which are exactly 45 degrees against main global or local axes, are not counted to any direction.

Steel embeds are ignored when calculating the AREA_FORM_... values of cast units.

AREA_FORM_TOP = 42 sq.ft.

AREA_FORM_BOTTOM = 42 sq.ft.

AREA_FORM_SIDE = 2*(2*7 + 3*6) + 2*(2*6 + 2*6) = 64 + 48 = 112 sq.ft.
