Photometric Web Converter Overview

The Convert Tool allows you to modify the photometric web for a selected file. The following options are available:

• Change the Photometric Type (e.g., Convert Type C to Type B and vice versa)
• Change the photometric web by specifying a new angle set.
• Remove unwanted and/or unnecessary angles from the photometric file.
• Change the luminaire testing position by applying up to four aiming angles: Orient, Tilt, Roll and Spin.
• The candela precision used in the original file is used when converting the file. For example: If the candela values in the original file have (2) decimals of precision, the candela values in the converted will have (2) decimals of precision.

Important! Converting a photometric file will affect its performance in PTB as well as other lighting software. Please make these changes with care, so as not to affect the integrity of the photometric file.

Convert Tool Buttons

The buttons displayed at the right edge of the Convert Tool provide the following functions:

• Ok - Completes the conversion process and closes the Convert Tool. The photometric file will be displayed with a Save icon in the Loaded Files list indicating its need to be saved. All open Tools with the same file will be updated as well. Note: If no conversions have been made, clicking Ok will not change the photometric file.
• Cancel - Cancels any modifications and closes the Convert Tool.
• Refresh - Allows you to convert the photometric file and refresh any corresponding tools using the loaded file. This functionality allows you to see the effect of converting the file without committing to any changes.

Subsequent conversions can be performed as desired. Note: All conversions are performed on the original file, conversion are not cumulative. For example: You apply a 25-degree tilt and convert (Refresh). You now change the tilt to 35-degrees. Since Convert always works with the original file, the resultant converted file will have a 35-degree tilt applied, not 60 (25 + 35).

• Work On - Specify whether changes are made to the original photometric file or to a copy. If the Copy option is selected, the new photometric file name is called "Copy_OriginalName".
• Settings - Displays the Convert Settings dialog allowing you to change some default specifications in the Convert Tool.
