Discover the Measurements in Kreo BIM Takeoff

Net Area:

-   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.
