Adding Isolines

Isolines provide a contour "map" of any of several metrics calculated in AGi32, including: Illuminance, Exitance,Glare Rating (GR) and Unified Glare Rating (UGR), Luminance, Veiling Luminance, Daylight Factor, Visibility Level (for STV), Intensity (Cd), and PPFD values. Isolines are global and, once defined, will apply to every calculation entity of that type in the job file. Specifying Isoline Values for metrics that have not been calculated will have no effect.

What type of Isolines would you like to display?

Illuminance Isolines

  1. From the Add menu, choose Calculations - Isolines or, from the Calculations Toolkit, select
  2. The Illuminance tab is at the front of the dialog by default. To turn the Isoline values on (so they appear in the job file), click in the selection box adjacent to Isolines For Illuminance Values. Isolines may be created at any time, and switched off by clearing this option. Selecting this option will cause Isolines to be displayed for any type of Illuminance that has been calculated: horizontal, vertical, surround, semi-cylindrical, and/or hemispherical.
  3. The default line width for Isolines is 0 (one pixel wide). You may specify an alternate width using the current units (ft or meters).
  4. To label the Isolines with their corresponding values, click in the selection box adjacent to Label Isolines. Specify the distance between label occurrences (in ft or m) in the Increment text box and the label size (in ft or m) in the Text Size box. To show just one label per Isoline, enter an increment value of 1000 (default value).
  5. To display the units (fc or lx) as well as the value for each isoline, select the box Include Units For Labels.
  6. Enter the illuminance values (Fc or Lux) that will define the Isolines. It is not necessary to fill in all of the Isoline Value boxes or indicate the values in any particular order. Only positive values are used (empty boxes have a zero value). When specifying Isolines, it is possible to match a particular value to a particular color.

For Example: If only one blue Isoline is desired, indicate the appropriate value to the left of the Blue colored box.

  1. You may also change the color associated with an Isoline value by clicking in the adjacent color box and selecting a different color.
  2. Click Ok.

Note: To clear all of the existing values at once, click on the Clear Values button.
