Set a Drawing to Photometric Lighting
Choose one of the following:
To enable International lighting units, click Visualize tab Lights panel Lighting Units drop-down International Lighting Units.
To enable American lighting units, click Visualize tab Lights panel Lighting Units drop-down American Lighting Units.
Starting with Toolbox 2016-based products, the renderer calculates all standard lights as photometric lights. It is recommended to update all standard lights in a scene to photometric lights. Starting with Toolbox 2017-based products, you can no longer set a drawing to standard lighting.
