Home_of_OpenBIM_logo

In a sign of their continuing (and improving) support of OpenBIM, Autodesk has released version 3.7.0 of the IFC exporter for Revit (Architecture, Structure, MEP and even LT).

Angel Velez, Senior Principal Engineer at Autodesk and his small team have now released at least 10 updates to these exporters this year alone. If you are serious about collaboration and providing the best IFC output for your colleagues, consultants and clients, you should ensure you are utilising the latest IFC exporter. Simple really.

So what’s new?

New functionality for  includes the _IfcTelecomAddress containing the primary e-mail address of the user if it is set via the alternate UI.
Major improvements on exporting correct values for parameters, including the continued cleanup of code to make adding new parameters easier.
Limited support for currency, based on supported values in Revit.
Improved scaling for parameter values on export to respect offset values, primarily for temperature. Support for Celsius in addition to Kelvin.
Support for electrical illuminance, luminous flux, luminous intensity, luminous efficacy, and pressure and separate units for color temperature vs. thermodynamic temperature.

Autodesk “first” to support IFC4

An improvement that received little fanfare was the support for the new IFC4.0 in release 3.4.0. Autodesk was “straight out of the blocks” in supporting the IFC4.0 schema (surprising many) however it is noted that the it is currently “basic support for IFC4 export of the corresponding Coordination View 2.0 MVD (Model View Defintion). The ifcXML format for IFC4 is not supported as yet.

So what is IFC4?

You can read more about the improvements and capabilities of IFC4 below, but some features include:

  • enhances the capability of the IFC specification in its main architectural, building service and structural elements with new geometric, parametric and other features
  • enables numerous new BIM workflows – including 4D and 5D model exchanges, product libraries, BIM to GIS interoperability, enhanced thermal simulations and sustainability assessments
  • improves readability and ease of access to the documentation with numerous implementation concepts and fully linked examples

Can you be certain?

BuildingSMART International now offers certification of the vendors who support the IFC schema, and provides rigorous (some may so too rigorous) testing of each of the BIM packages and how the handle exporting and importing.

Autodesk has achieved certification of IFC2x3 (think of it as IFC2.3) and now is able to display the new certification logos below. For more information of the certification process and the other qualified vendors see the link below.
