Acerca de esta versión

Versión 18.3.1, 26/02/2018
General: - This release focused on some additional UI and IFC4 improvements on export. These will be covered in more detail in various help documents. New Export Functionality: - Add the ability to import and export custom configuration setups. - Add the ability to choose the origin of the exported file. There are 4 options: - Current shared coordinates origin - Internal Revit coordinates - Project Base Point - Site Surve Point - A number of COBie improvements, including: - Including the exchange requirement information in the File Header - A number of IFC4 Reference View improvements, including: - Export some profile names with geometry when appropriate - Fix scaling of triangulation coordinates - Improve export of beam axis - Restrict use of many disallowed IFC entities and geometries - Allow remapping of IFC entity attributes in addition to properties. - Create more associated type entities for IFC objects. - Consistent ability to override name, object type and description for all entities - Export connectors even if they aren't connected to other elements. - Export parts whose host elements are in linked files, whether "Export Parts as Building Elements" is checked or not. - Improved creation of IFCBUILDING and IFCSITE entities Export Bug Fixes: - Fix export of some space with empty Occupant fields. - Fix relative placement of exported IFC links to the host IFC file. - Fix unexpected error when exporting a floor as an IfcRamp (for IFC2x3 only). - Fix unexpected error when exporting a site from a 3D view when exporting the active view geometry (for IFC4 RV only). - Full French localization for a number of previously hard-coded strings - Improved calculation of some property set parameters.

  • User defined property sets causes export failure
    Tommy Boonrod | marzo 01, 2018 Descarga verificada (¿Qué es esto?)

    When I use my settings file I am unable to export to IFC. It works if I use default settings or if I uninstall IFC 2018 plugin. Here is my settings file - http://www.bipkoder.se/resources/BIP_EL_JBack_2018.zip

    We've identified the issue: we have the wrong label for ElectricVoltage in our code. We are going to fix this. In the meantime, if you remove that one line, it should work for you.

  • How can I check the Version of the installed IFC 2018?
    M. Steffan Noé | enero 16, 2018

    Is there a way to keep me notified about updates without using the Desktop App. We are using SCCM and the Desktop App will not be used. Thanks a lot

    We currently send emails that you can opt out of receiving when there is a new version.

    This version fixed export geometry in active view problem.

  • IFC export coordinates clarity needed
    Brian Renehan | junio 04, 2017

    Dear Autodesk We as regular IFC users, require absolute clarity from Autodesk with regard to exactly how this plugin is exporting the IFC file coordinates. There are no clear answers on any of the Revit Help pages or this exports help files. From what I can establish, the IFC export uses the Survey point origin as the IFC export origin in an X, Y,Z, direction, and the internal origin and its rotation relationship to the Survey point is recorded in the IFCSite Local Placement (IfcLocalPlacement) information. Can you confirm is the above is correct? How does this relate to the IFCSITE elevation export setting? We request Autodesk please add this critical workflow information to the Autodesk Revit help files. We also request in the Export function: Users have the choice so as they can export the IFC file coordinates to the Survey point, Project Base Point or Internal Origin. This would also include what origin point is used for the IfcLocalPlacement. Other applications now have IFC origin options. This is vital for effective Site and Building Coordination. The project team can establish the workflow that suits them best. On IFC Import into Revit, we also need to have options on which origin point we use to import (Survey point, Project Base point or Internal Origin as wall as the IFC Absolute origin or IFC Local Placement). Try importing a Civil In-ground services file to MGA (Map Grid of Australia – Northing’s of 5,600km away) and see what kinds of results you get. Currently, we have to do other workarounds using other plugins and applications to resolve this issue collaboration issue. Building designers need to be able to work with Civil consultants using real world coordiantes. I look forward to your response. Thanks and kind regards Brian Renehan
