![]() This method can be quite effective, as in most cases the variety typically comes from product options and finishes rather than from different photometrics. In this case, we end up with built-in types for each corresponding IES file rather than for each product type. ![]() Then you embed the required IES files within this nested family's types and, finally, via type catalog, control which nested type is displayed for each light fixture type. This is typically how lighting fixture families with few types are distributed.įor families with too many types to justify leaving them built-in, the common technique is to nest another lighting fixture with no geometry and only the light source defined. rfa file - though manufacturers will often offer the IES files separately too. Distributing the family is then just a matter of sharing the. For built-in types, Revit will cache the used IES within the family itself. IES files are added to a lighting fixture Revit family by pointing the built-in Photometric Web File parameter to them. Lighting Fixture Revit family with the Light Source displayed using an IES Photometric Web File. In certain situations, it might also be advisable to break down the light fixture into two or more families. ![]() The process involves using type catalogs with embedded IES files, keeping the family file and the project nimble. In this article, I will discuss how a lighting manufacturer can make Revit families with IES files that perform better and are lighter - no pun intended - than the standard approach. These provide a much more detailed definition of a light source's properties. ![]() For manufacturer-specific light fixtures, however, Revit allows the use of industry-standard IES files. The light source shows as a yellow mesh in the family editor and is used for renderings and lighting calculations.Ī quick way to set a light source is to use the Light Source Definition dialog to define its shape (point, line, rectangle and circle) and distribution (spherical, hemispherical and spot). To view the effects of light sources in a rendering within Revit, lighting fixture families include a built-in option for light source. How to build manufacturer-specific lighting fixtures in Revit that perform better using IES files in type catalogs. ![]()
