Area of the largest surface of an object, excluding voids.

Double Net Area:

Calculated as “Net Area * 2”.

Gross Area:

Area of the largest surface of an object, including voids.

Double Gross Area:

Calculated as “Gross Area * 2”.

Net Side Surface Area:

Side surface area of an object, excluding voids on the sides.

Gross Side Surface Area:

Side surface area of an object, including voids on the sides.

Outer Surface Area:

Total area of a object, excluding voids and end faces (horizontal faces for a column and 2 minimal vertical faces for a beam).

Outer Surface Area Without Top:

Total surface area of an object, excluding top and end faces.

Min Double Face Area:

Double area of the smallest surface of an object, including voids.

Mid Double Face Area:

Double area of the medium surface of an object, including voids.

Max Double Face Area:

Double area of the largest surface of an object, including voids.

Net Top Area:

Area of the top surface of an object, excluding voids.

Net Bottom Area:

Area of the bottom surface of an object, excluding voids.

Gross Volume:

Gross Volume for concrete beams (before cutting the volumes of an adjacent slab and adjacent columns from a beam, often used to calculate the weight of reinforcement bars).

Net Volume:

Volume of an object, excluding voids.

Length:

The largest linear dimension of an object.

Projection Length:

Plain projection of the linear length of an object.

Steps Length:

The total length of all steps of the stairs.

Total Perimeter:

Perimeter of the horizontal section of the wall or the floor, including perimeter of inner voids (suited for slanted objects too).

Outer Perimeter:

Perimeter of the horizontal section of the wall or the floor (suited for slanted objects too).

Perimeter Without Doors:

Perimeter which is calculated in the same way as "Outer Perimeter", subtracting the width of the doorway. Can only be calculated in locations.

Quantity:

Number of objects with the same properties in a model.
