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(1) part that exists in a building object and that determines the position number for the assembly or cast unit and the direction of assembly or cast unit drawings

(1) Main part can be an assembly main part or a cast unit main part.

(2) input part that the user selects first when creating a component

(2) Connections and details always have a component main part.

local up directionconnection or detail property that indicates how the created connection is rotated around the component secondary part, or the created detail around the component main part, relative to the current work plane

The up direction options are +x, -x, +y, -y, +z, -z, and auto.

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.
