IFC for Revit Files

This directory contains installs based on the IFC Exporter UI code.  New installs will be created when:
- There is a major Revit release or update release.
- There is a critical change to the source code.
- Periodically, if any significant changes have been made since the last install.  This is currently intended to happen around the end of the month.

Version Log:

(1.17.0) IFC Export UI for Autodesk Revit 2013 v1.17.0.msi
IFC Export UI for Autodesk Revit 2013 Source v1.17.0.zip

New Functionality:

- Add option to export user defined property sets.  Please see the SourceForge wiki for more information on what is currently supported.
- Added "IFC2x3 Extended FM Handover View" configuration to UI.  Use this option if you want to maximally extract COBie data from the IFC file.

(1.16.0) IFC Export UI for Autodesk Revit 2013 v1.16.0.msi
IFC Export UI for Autodesk Revit 2013 Source v1.16.0.zip

New Functionality:

- Add "Classification Field Name" to Classification tab in Assignments.  This allows a user to specify the name of one field that will serve as a classification.
- Add "Phase to Export" UI to allow user to choose which phase to export.  This field is grayed out if exporting the current view.

Bug Fixes:

- Fix "Duplicate" button in the export setup dialog to respond to left-clicking.

(1.13.0) IFC Export UI for Autodesk Revit 2013 v1.13.0.msi
IFC Export UI for Autodesk Revit 2013 Source v1.13.0.zip

New Functionality

- Add UI version number to title of the IFC Export dialog box.
- Add option to export schedules as custom property sets.  The name of the schedule is the property set name; the column names are the IFC parameter names.
- Add option to export solid models, which allow for mixing BRep and extrusion geometries for an entity.  This can result in smaller IFC files.
- Remove option to disable surface styles on export.
- Remove option to export advanced swept solids.

(1.12.0) IFC Export UI for Autodesk Revit 2013 v1.12.0.msi
IFC Export UI for Autodesk Revit 2013 Source v1.12.0.zip

- Optionally allow storing the generated IFC GUIDs into the project file after export.  This will add "IFC GUID" parameters to elements and their types, and Project Information for Project, Site, and Building GUIDS.  This requires v2.12 of the expoter to add the parameter values, and also requires a manual save.
- Report which property sets are being exported on a single line in the detail section of the first export screen.

(1.11.0) IFC Export UI for Autodesk Revit 2013 v1.11.0.msi
IFC Export UI for Autodesk Revit 2013 Source v1.11.0.zip

- Added "Use coarse tessellation for some BReps" option, defaulting to true. 

(1.10.0) IFC Export UI for Autodesk Revit 2013 v1.10.0.msi
IFC Export UI for Autodesk Revit 2013 Source v1.10.0.zip

New Functionality:

- Add property sets: Pset_ElectricalDeviceCommon, Pset_SwitchingDeviceTypeCommon, Pset_SwitchingDeviceTypeToggleSwitch
- Add support for electrical current, electrical voltage, frequency, and positive plane angle units.
- Allow Name/ObjectType/Description override fo IfcSystem.
- Allow using "IfcExportAs" = "DontExport" to remove an individual element or type from the export.
- Export DuctLining.
- Export Groups, including nested groups, as IfcGroup.
- Export electrical systems and connectors.
- Export local coordinate system for IfcDistributionPorts.
- Export PipeInsulation.

Bug Fixes:

- Allow MEP zones to export Pset_ZoneCommon, fix 2 property names.
- Correct export of parts for Coordination View 2.0.
- Correct height of Revit Areas.
- Correct material assignment for generic MEP exporter.
- Correct units and unit scaling for volumetric flow rate.
- Fix export of multi-storey stairs.
- Get material for ducts and pipes from system.
- Properly associate internal ElementType Revit property sets with IfcElementType, instead of adding to instances.
- Properly scale door and window lining properties.
- Protect against trying to add a null property to an IfcPropertySet.
- Remove extraneous property sets when exporting Rebars.
- Remove stale IfcSurfaceStyle and IfcPresentationStyleAssignment handles from caches for some aborted attempts to export items as multiple IfcExtrudedAreaSolid.
- Return correct boolean value for GetBooleanAtribute function.

(1.8.1) IFC Export UI for Autodesk Revit 2013 v1.8.1.msi
IFC Export UI for Autodesk Revit 2013 Source v1.8.1.zip

- Correct default settings for some built-in configurations.
- Correct space boundary combobox location.

(1.8.0) IFC Export UI for Autodesk Revit 2013 v1.8.0.msi
IFC Export UI for Autodesk Revit 2013 Source v1.8.0.zip

- Add a "Classification" tab to allow specification and export of a user-defined classification system, instead of just Uniformat.
- Allow choice of whether to include the elevation offset of IfcSite in the local placement of the IfcSite as a UI option.  By default, the elevation offset is NOT included in the local placement as of version 2.7/1.7 of the exporter.  Note that currently this override is disallowed for Coordination View 2.0 files; if there is a demand for this, we will consider allowing it with a comment in the IFC file itself.  Note that this UI change needs Exporter v2.8 to work properly.
- Export surface styles by default for Coordination View 2.0.

(1.7.0) IFC Export UI for Autodesk Revit 2013 v1.7.0.msi
IFC Export UI for Autodesk Revit 2013 Source v1.7.0.zip

- Added new "FMHandOver" view configuration.
- Added UI for specifying FILE_HEADER and IfcPostalAddress information.  This infomration is used by Exporter v2.7.0.

(1.6.0) IFC Export UI for Autodesk Revit 2013 v1.6.0.msi
IFC Export UI for Autodesk Revit 2013 Source v1.6.0.zip

- Add the version number of the Alternate UI to the header of the IFC file.
- Add option "ExportAdvancedSweptSolids" to allow the export of advanced swept solids (Note: the use of this is currently limited in Revit, and other systems will have limited support for them).
- Add option "ExportBoundingBox" to export a bounding box representation in addition to the geometry.

(1.3.0) IFC Export UI for Autodesk Revit 2013 v1.3.0.msi
IFC Export UI for Autodesk Revit 2013 Source v1.3.0.zip

- Fixed a failure to export in certain cases when Alternate UI was upgraded to a newer version.

(1.2.0) IFC Export UI for Autodesk Revit 2013 v1.2.0.msi
IFC Export UI for Autodesk Revit 2013 Source v1.2.0.zip

- Add option "Export Surface Styles" that controls whether surface styles are exported or not. 
- Add option "IFC Common Property Sets" that controls whether Revit parameter groups are exported as IFC property sets or not at all.

(1.1.0) IFC Export UI for Autodesk Revit 2013 v1.1.0.msi
IFC Export UI for Autodesk Revit 2013 Source v1.1.0.zip

- Add option "Export parts as Building elements" to allow parts to be exported as separate entities (requires setting Visible elements in current view option)

(1.0.0) IFC Export UI for Autodesk Revit 2013 v1.0.0.msi

Initial release, based on Revit 2013.
