BIM (Building Information Modeling) is an intelligent, 3-D model-based process for planning, design, construction and management of buildings and infrastructure. Revit is one of the BIM platforms (software packages) used to create BIM models.

What is a Revit file?

A Revit file is the output from the software. It can be in one of three formats:

A Revit file is the output from the software. It can be in one of three formats: RTE (Revit Template File), RFA (Revit Family File), RVT (Revit Project File).

Why does an LED Revit family emit various colors in a rendering?

This is the result of the IES file(s):

Read Full Answer

This is the result of the IES file(s):

Revit seems to have an issue with "reading" absolute IES files for LED lighting fixtures. The IES file notes a "-1" for the initial lumens value.

A discretionary approach is to change the "-1" to the initial lumen value of the LED lighting fixture, save (you may want to add characters to the end of the filename to differentiate it from the original IES file) and reload the IES file in the Photometric Web File parameter.

What is a type catalog?

A type catalog (comma-delimited text file (.txt)) is an external file that contains specified syntax for family types and parameters...

Read Full Answer

A type catalog (comma-delimited text file (.txt)) is an external file that contains specified syntax for family types and parameters. It is best practice to keep the list of family types within the model to six or less. If more are needed, a type catalog with specified syntax should be created.

The type catalog file must be in the same folder and location and have the same file name as the corresponding Revit family; if not, the types and data will not load into a project file.

How do I load a Revit family that has a type catalog into a project file?

From your project file, click Load Family located under the Insert menu.

From your project file, click Load Family located under the Insert menu.

Does Eaton’s lighting division provide 2D CAD files of its products?

Eaton's lighting division provides 2D CAD files of products by request.

Read Full Answer

At this time, we only provide 2D CAD files of products by request. If you need a more detailed 2D CAD drawing (similar to what’s shown in a specification sheet), our engineering department can address your request.

Glossary of Lighting Terms

  • Underwriter’s Laboratory (UL)

    A private organization that tests and lists electrical and other equipment for electrical and fire safety according to established UL and other standards. A UL listing is not a sign of overall performance. Compact fluorescent and LED lamp assemblies – those with screw bases and built-in ballasts – are the only lamps that are UL listed.

  • Integrated circuit (IC)

    IC-based compact fluorescent lamps (CFLs) operate by controlling the voltage and current by adjusting the output frequency, which provides stable operation of the CFL. Controlling the current produces less stress on the cathode and the electronic components; this results in longer life, smoother dimming and less noise.

  • L70 Hours

    Used to describe the LED’s expected light output over its stated life span. “L70” predicts when the LED reaches 70% of initial lumen output. Lumen maintenance is a prediction of the number of hours an LED will operate before it fades below a useful level of intensity.

  • LED Array

    An assembly of LEDs on a circuit board. Can include optical elements and additional thermal, mechanical and electrical interfaces that are intended to connect to the load side of an LED driver.

  • LED Luminaire

    A complete lighting unit consisting of LED-based elements and all necessary components: driver, parts to distribute the light, and parts to position and protect the light-emitting elements and connect the unit to a circuit branch.

  • Light loss factor (LLF)

    A factor used in calculating luminance over a given period of time and under given conditions. It accounts for light loss due to temperature and voltage variations, dirt accumulation on luminaire, lamp depreciation, maintenance procedures and atmosphere conditions.

  • Vertical aiming angles

    The degrees below horizontal that light fixtures are aimed at the field. Angles are measured from a horizontal plane at fixture height. Critical in safe, playable lighting design.

  • Junction temperature (TJ)

    The highest temperature of the actual semiconductor in an electronic device.

  • Kelvin

    The Kelvin unit is the basis of all temperature measurement. In lighting, Kelvin is the unit of measure for color temperature used to indicate the overall color of the light produced from a source. See “correlated color temperature.”
