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.

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

  • DC (direct current)

    When electrical current and distribution flows in one direction through the conductor. Battery-operated systems are typical DC applications.

  • Lumens per watt (LPW)

    A measure of the efficacy (efficiency) of a light source. The number is achieved by dividing lumens produced by watts consumed.

  • Flicker

    The (potentially visible) temporal variation of emitted light.

  • Ghosting

    An effect that occurs when lighting fixtures in the off state faintly glow as a result of residual voltage in the circuit.

  • Uniformity ratio

    Either the ratio of the illuminance in the brightest-lit spots to that in the dimmest areas (max/min), or of the average illuminance of the whole area to that of the dimmest spots (avg/min). The best results as far as visual acuity result when the uniformity ratio is close to one.

  • Power factor (PF)

    The measurement of the relationship between the AC source voltage and current. Power factors can range from 0 to 1.0, with 1.0 being ideal. Power factor is a measure of how efficiently electrical power is being used. The higher the power factor, the more efficient.

  • Kilowatt hour (kWh)

    The measure of electrical energy from which electricity billing is determined. For example, at the rate of $0.11 per kWh, a 100 watt lamp operating for 1,000 hours will cost $11.00 (100 x 1,000/1,000 = 100 kWh x .11 = $11.00).

  • Ambient lighting layer

    The layer of light that serves as general illumination for a space for basic visual recognition and movement.

  • Bulb

    The glass part of the lamp. Lamps are produced with a variety of bulb shapes. LED light fixtures do not utilize a bulb.
