Adding Statistical Areas

Statistical Areas allow you to calculate values within any user-defined region. You may break a single calculation plane into numerous statistical areas or combine the results of multiple calculation entities into one statistical area. Statistical areas consider the points within and on the polygon boundary and the results are shown in the Statistics Window. Statistical areas may overlap without influence.

Statistical Areas are dynamic entities that update with every redraw. This allows you to place them at any time in the design process.

1. From the Add menu, choose Calculations - Statistical Area or, from the Calculations Toolkit, select .
2. Specify a unique label for this statistical area, up to 32 characters long. The default label will be StatArea_1. Unless changed, subsequent labels will be StatArea_2, StatArea_3, etc. If a number is used for the label, subsequent labels will be incremented accordingly.
3. An optional description, up to 80 characters long, may be entered.
4. The Summarize Project list indicates the project the Statistical Area will extract information from. The Statistical Area may be attached to one project (usually the current project) but summarize another project or all projects. For example, you may wish the Statistical Area to summarize a project containing vertical illuminance calculation points although the Statistical Area is in another project. By default, Statistical Areas summarize all projects.
5. Select the type of calculation value to consider; Illuminance, Exitance, Glare Rating, Luminance (Diffuse, as specified in Automatic Placement), Roadway Luminance, Veiling Luminance or Unified Glare Rating (UGR). Note: The Illuminance value type include any illuminance types that have been calculated, e.g., vertical, semi-cylindrical, etc. The Roadway Luminance value type includes all luminance-related grid types that have been calculated, e.g., Longitudinal Uniformity, Background Luminance, etc. If the calculation type does not exist within the statistical boundary, zeroes will be displayed.
6. The default Line Color is black. This can be changed by clicking in the color field and, in the dialog that opens, selecting a different color.
7. Click on the Labeling button to select the information to be included as part of the Statistical Area label, which will be located adjacent to the Statistical Area in the job file. If no label is desired, click on the Clear Labeling button
8. In the Summary section, select which analysis will be displayed in the Statistics window. Maximum/Average ratio and Number of Points are not selected by default.
9. Select the label information to be included in the Statistical Area label adjacent to the statistical area in the job file. If no label is desired, simply clear all of the selection boxes in this section.
10. If desired, change the text font or text size.
11. Creation Method: Choose whether to manually create boundary lines of Statistical Area or choose an existing line, room or object as the boundary line.
• In Plan View, Z coordinate is always 0.
• If a tilted line, object or room is selected, polygon will be projected down to and created at lowest Z coordinate elevation.
12. Click OK. Follow the steps below depending on the selected creation method:

Specify a Polygon Manually

Create Polygon from Drawing Entity, Room or Object

Locate the first point of the polygon and click the left mouse button. Move the cursor to the second vertex on the polygon and left click again. Continue in this fashion until the polygon is complete. Right click to close the polygon shape. The Statistical Area will be created.

Locate the pick box on the drawing entity line, object or room boundary you wish to use and left click. If a valid polygon is found (see Notes below), it will be displayed as a bold line, and the Polygon Search results dialog will appear: Accept Polygon and Repeat - Select another polygon line as a template for another Statistical Area with the same properties. Use pickbox to select another closed polygon. Accept Polygon - Create Statistical Area using selected entity as polygon boundary. Reselect Entities - Choose this option if invalid polygon was found or if incorrect line was chosen. Use pickbox to select another closed polygon. Manually Specify Polygon - Select vertices manually to specify polygon boundary, right clicking once all vertices are specified. This option is necessary if no valid polygon is found. Cancel - Do not create Statistical Area. Notes: Drawing Entity line segments do not need to be joined, just need to be within tolerances (2 decimals of precision - .05) Line segments do not need to make a closed polygon - AGi32 will automatically close boundary line AGi32 filters related lines by color. Caveats: Disconnected line segments or line segments disconnected by gap larger than tolerance level will not form valid polygon. Polygons with intersecting lines will not form valid polygon. Incomplete polygons are not valid, may close in an unacceptable manner.
