Using photometric threshold settings
Vectorworks’ photometric grid and photometer calculate and display the illumination values at the elevation point. The values are displayed in either foot candles (Imperial) or lux (Metric), depending on the units selected in File > Document Settings > Units. The pen color of each indicator provides a visual cue of the light intensity according to defined ranges, which are specified here.
To specify threshold settings:
From the Object Info palette of either a photometric grid or photometer, click Threshold Settings.
The Threshold Settings dialog box opens.
