Add Calculations - Scattered Illuminance Points

This command allows you to specify individual points for which illuminance values will be calculated. Scattered Points are specified in Plan view.

1. From the Add menu choose Calculations - Scattered, or from the Calculations Toolkit select .
2. Specify a unique label up to 32 characters. The default label will be CalcPts_1. Unless changed, subsequent labels will be CalcPts_2, CalcPts_3, etc. If a number is used for the label, subsequent labels will be incremented accordingly.
3. An optional description may be entered up to 80 characters. Meaningful descriptions that include size and color information will be useful when generating schedules.
4. Specify the text size. By default, a text size of 5 is used.
5. Select the light meter type.
6. Specify the Summary options to calculate. By default, average, maximum and minimum illuminance are displayed along with uniformity ratios (Max/Avg ratio is not selected by default). If Number of Points is selected, the number of points that are in the calculation (not including points that have been removed) is shown.
7. Select the display options, including precision, text color, point markers, meter direction indicators, and labeling.
8. Specify the Z coordinates of the first point. You will have the option to change the Z coordinate of each point, if desired, during the location process. By default, this value is set to zero.
9. If desired, specify Highlight Values by clicking on the Highlight Values button.
10. Click Ok to begin point placement.
11. To change the point elevation, move the cursor into the Z-Coord text box and enter a new value or use the up and down arrow keys on the keyboard, before clicking the first point. Locate the first point and click the left mouse button.
12. Drag the cursor to an additional point location and left click again. By default, the current Z coordinate will echo the first point's elevation. To change the elevation for the next point, before clicking move the cursor into the Z-Coord text box and enter a new value or use the up and down arrow keys on the keyboard.
13. Continue in this fashion until complete. Click the right mouse button to confirm your point locations.

NOTES:

• The meter indicators are "off" by default. They may be turned on by unchecking the appropriate box in the dialog.
• Compatibility with earlier versions: If selected, meter indicators will be displayed in older versions of AGi32 until the calc points are edited.

As an alternative to placing points one at a time, you may choose to import a set of points in the form of a text file. To do this, click on the Import Points button. In the dialog that opens, navigate to the file and click OK. About the text file:

• We recommend that the file have extension .txt
• Each point is specified as X,Y,Z values (with or without spaces)
• One point (X,Y,Z) per line
• Example:

100, 0, 0

110, 10, 0

150, 50, 3

200, 45, 15

200, 37, 0
