Dimensions in specter
If building elements in the model have been assigned dimensions, these can be displayed using the info box in specter.
Overview of Dimensions
1. Height
The vertical extent of an object, measured from the base to the top surface.
2. Lenght
The horizontal extent of an object along its longer side.
3. Width
The horizontal extent of an object along its shorter side.
4. Footprint Area
Gross: The total floor area of an object, including all openings that are not part of the actual surface.
(green = relevant area(s))
Net: The floor area of an object excluding openings (e.g. windows, doors), i.e. the actual usable area.
(green = relevant area(s))
5. Volume
The vertical extent of an object, measured from the base to the top surface.
Gross: The total volume of an object, covering the full space regardless of openings.
Net: The volume excluding the space taken up by openings (e.g. areas behind windows or doors that are not usable).
6. Side Areas
Gross: The total surface area of the sides of an object, without accounting for openings.
(red = areas not considered)
(green = relevant area(s))
Net: The side surface area excluding any openings.
(red = areas not considered)
(green = relevant area(s))
7. Total Surface Area
Net: The sum of all usable surfaces that can actually be touched, excluding all openings.
(green = relevant area(s))
Gross: The sum of all surfaces, including those with doors or other openings.
(red = areas not considered)
(green = relevant area(s))
8. Shell Area
Gross: This includes all outer sides of an object.
(red = areas not considered)
(red = areas not considered)
(green = relevant area(s))
Net: This includes only the outer vertical sides, excluding the top and bottom, and deducting any openings.
(red = areas not considered)
(red = areas not considered)
(green = relevant area(s))
Difference Between Gross and Net
Gross: Refers to the total size or area of an object, without subtracting openings, walls, or other non-usable features. Gross values provide an overview of the full extent of an object.
Net: Refers to the actual usable size or area, excluding openings, walls, and non-functional parts. Net values are more relevant when evaluating usable space.
Summary
Distinguishing between gross and net values is crucial to understand the real usability of a space or object. Gross dimensions indicate the total size, while net dimensions represent the usable space or volume.
