Displays properties for general lighting zones. A zone is a pre-defined space in the model.
The order in which the properties display in your view depends on your configuration.
Space Folder
A space folder is used to organize space management objects.
General Light Count
Specifies the number of and type of lights needed to provide uniform illumination for the entire space. This value is calculated by determining the total light loss factor, which is then used to calculate the number of lights, as shown in the equations below.
Total Light Loss Factor = CU x LLD x LDD
Where:
CU = Coefficient of Utilization
LLD = Lamp Lumens Depreciation
LDD = Lamp Dirt Depreciation
And
The equations above are used for all lighting zones except Street Light. The following
equation is used to determine the number of street lights.
Task Light Count
Specifies the number of lights needed to focus on a small part of the area. You define this value.
Electrical Panel Count
Specifies the number of circuit breakers in the panel. This number is determined by the breaker panel load, which is calculated using the equation below.
Illuminance Level
Specifies the total light incident on a surface. The software uses the default value from the catalog; however, you can change this value.
Fixture Purpose
Specifies the purpose for the lighting fixture. Select Undefined, General, Floodlight, or Street.
Fixture Type
Specifies the type of lighting fixture. Select the type from the list.
Lumen per Fixture
Specifies the amount of light (lumens) generated by a specific light source (fixture). This value is read-only. The software derives the default Lumen Per Fixture value from the lookup table in the Catalog using the combinations of the Fixture Type, Fixture Purpose, and Wattage settings.
Coefficient of Utilization (CU)
Specifies the measure of efficiency in which a luminaire transfers luminous energy to the exposed area. This value is expressed as a ratio. The software uses the default value from the catalog; however, you can change this value.
Lamp Lumen Depreciation (LLD)
Specifies the loss of the original light output from the fixture over time. This value is expressed as a ratio. The software uses the default value from the catalog; however, you can change this value.
Lamp Dirt Depreciation (LDD)
Compares the efficiency of a new, clean luminaire to a luminaire with accumulated dirt. This value is expressed as a ratio. The software uses the default value from the catalog; however, you can change this value.
Total Light Loss Factor
Predicts the performance based on the luminaire properties.
Voltage
Displays the voltage values available in the catalog.
Electrical Breaker Load Factor
Specifies the efficiency of the electrical energy use. The software uses the default value from the catalog; however, you can change this value.
Electrical Circuit Rating
Specifies the lowest current rating of the wire or the circuit breaker rated for the circuit. This property displays all the values available from the catalog.
Circuit Count per Panel
Specifies the number of distribution points for electrical circuits. This property displays all the values available from the catalog.
Projected Area
Specifies the area of the bottom surface of the cuboidal volume.
Projected Length
Specifies the length of the longest edge of the bottom surface of the cuboidal volume.
Type
Specifies the light category (for example, Miscellaneous Lighting).
Part Definition
Specifies the part information for the object, the properties, and their values, as defined in the reference data. For information about the information defined in the reference data, see the appropriate Reference Data Help.
Surface Area
Displays the total surface area of the selected Space Management volume. This property is read-only and is not shown during object creation.
Volume
Specifies the volume of the compartment or zone.
Permission Group
Specifies the permission group to which the object belongs. You can select another permission group, if required. Permission groups are created in Project Management.
Approval State
Specifies the status of the selected object or filter. Changing this property sets the Status. The display depends on your access level. You might be unable to change the status of the object. The list is defined by the ApprovalStatus codelist.
Smart 3Dx saves an object to the database when you change that object's status. Use Undo (CTRL + Z) 
to reverse the status change.
You can only edit or manipulate an object with a status of Working.
Date Created
Specifies the creation date of the object.
Created by
Specifies the name of the person who created the object.
Date Last Modified
Specifies the date of the last modification to the object.
Last Modified by
Specifies the name of the person who last modified the object.
Orientation
Specifies the orientation for the coordinate system.
Class
Displays the object class defined by the software.
Description
Displays information about the placed volume.
Zone Type
Displays the zone Type of the volume.
