Release Date: 2008-09-29
This version of Revit® Structure 2009 is a native 64-bit application to be used with 64-bit Operating Systems, such as Microsoft® Windows® XP Professional 64-bit or Microsoft® Windows Vista® 64-bit (Business, Home Premium, Ultimate editions). The 64-bit version of Revit Structure 2009 removes the 4 gig memory limitation found in 32-bit applications which enhances the software’s capability to handle large projects. It contains the functionality found in the 32-bit release of Revit Structure 2009, with the noted limitations found in the Known Issues document.
Revit Structure 2009 (64-bit only)
- Revit® 64-bit products can access additional RAM in computers containing more than 4GB of memory. Due to the inherent application memory access limits of Revit 32-bit products, it will be possible for 64-bit Revit products to create models that 32-bit Revit products will be unable to open. If this situation is encountered, the problematic model must be divided into two or more models small enough to be opened in the more limited memory available to Revit 32-bit applications.
- ODBC export is limited to those formats for which Microsoft has provided 64-bit drivers. At the time of this release, drivers to export to Microsoft Excel and Microsoft Access are
unavailable for Microsoft Windows 64-bit operating systems.
- The Autodesk DWF Printer is unavailable for the Revit platform products in 64-bit. DWF
files may still be created with Revit’s DWF Publish option.
Revit Structure 2009 (32-bit and 64-bit)
Wall Foundation end adjustment
- The Wall Foundation property “Do Not Break at Inserts” will not have any effect on holes
created by Opening elements, it only works with instances (like Doors) that can be inserted.
Concrete End Joins
- New behavior is limited to Concrete Beams with the following properties:
- Rectangular Sections with Cross Sectional Rotation that equal 0, 90, 180, and 270 degrees.
- Trapezoidal, T-shaped, and L-Shaped Sections with Cross Sectional Rotation that equal 0 degrees.
- Beams must have constant profiles (non-tapered, non-twisted)
- No member in the join may be sloped.
- Only beams lying in horizontal work-planes.
- Beams that don’t meet the criteria listed above will exhibit old behavior.
- Upgraded files will exhibit old behavior until a new beam is added to the join.
- Shape Handles are not available for elements participating with new behavior.
- Type parameter changes will not automatically update Concrete join geometry.
Automatic Join Geometry
- Hierarchal joining rules between element categories cannot be changed, e.g. Slabs always cut Columns when using Join Geometry.
- Automatic Join Geometry does not occur between Wall and Slab categories.
- It is not possible to disable automatic Join Geometry, but joins can be manually unjoined.
- Joined geometry may impact performance.
- While placing Rebar, temporary dimensions and snapping is unavailable.
- Rebar cannot be placed unless the element is cut and the workplane is within View Range, except for Slabs and Walls.
- Standard Rebar will not join to fillets of stirrup/tie rebar.
- Angular constraints are not allowed in Rebar Shape definitions.
- View regeneration may be slow in Views using Fine level of detail with a large number of Rebar elements within View Range.
- Rebar can only be placed or sketched when a Rebar Family is loaded in the project.
- Family parameters cannot be added to Rebar Shape Families.
- New Rebar functionality only pertains to newly created elements. Rebar elements created in prior versions will exhibit old behavior.
- Area and Path Reinforcement type parameters no longer exist for newly created elements, therefore no identity data parameters exist for these elements.
- On-screen display of hidden lines may not match vector output (e.g. Print, Export) in some cases.
- Some edges of Wall ends will not show as hidden.
- Metal Deck profile at the projected face of Openings may not align with the Metal Deck profile of the Slab.
- Metal Deck may not be shown correctly for some curved projected faces.
Slab Shape Edit
- After clicking Pick Supports for a sloped slab, changing the Curved Edge Condition to “Project to Side” causes the shape edit to fail for some curved edges. Temporary workaround: delete the offending curve.
Beam Extension and Mitering at end Join
- Mitering non-Concrete Beams is limited to 2 Beams of the same type within the same plane.
- Lines within the Beam family (e.g. hidden lines) will not Trim/Extend to the miter plane.
- Beam shape handles do not participate in extensions.
- Edit Beam Join editor is not available when a concrete beam is participating in the end join.
- Beams that have been mitered at any time during their life will be cut by the Cut Plane in Plan Views using Medium/Fine Detail Level.
- Only one Spot Elevation Type can be used by the tool at one time.
- Spot Elevation Types and Structural Framing Tags must have the Type parameter “Rotate Component” enabled to be available in the drop down.
Dimension Text Overrides
- For a multi-segment dimension string in which one of the dimensions has had a dimension text override, adding a new segment to the string will cause the override to disappear.
Dimension Type Text Sizes
- Dimension Types lose their previous Text Size changes when a Duplicate Type is created.
- Fill Patterns can now be applied to most surfaces (including warped planes), however:
- Only patterns on planar surfaces can currently be moved or rotated.
- Some complex surfaces may exhibit undesirable anomalies (such as areas of missing pattern).
- Currently, detail components do not support aligning fill patterns to the element Far Clip
Parameter and Linked Files
- While Linked files can now be displayed By Linked View in Sections, Elevation and 3D
views, the Far Clipping Parameter in Section and Elevation views will always display per
the Host view’s settings and NOT by the Linked View’s settings – even when the Link is
set to display By Linked View.
Large DWG Imports
- DWG™ imports with entities further than two miles apart (after scaling) may cause accuracy issues. Very large DWG imports should be subdivided into smaller files.
- DWG imports with coordinates (before scaling) longer than ten digits may be truncated to zero and become corrupted.
Upgrading very large files from previous versions of Revit Structure
- Upgrade of some very large Revit Structure files (~200 MB and greater) may cause Revit
Structure to crash by exceeding the maximum memory usage allowed by the operating
system. Please contact Autodesk® Product Support.
- Revit® Structure 2009 software contains a new rendering engine that makes major changes in the previous workflow. See the Revit Structure Feature Summary and Help documentation for information and instructions.
- When rendering an uncropped 3D view, geometry may appear shifted. Workaround: turn on crop region for the view.
- Non-English builds of Revit currently display RPC ID’s instead of names for downloaded
The Front orientation in ViewCube in a published DWF
- Currently, if the Front orientation in ViewCube™ software is changed from its default setting in Revit Structure, the change will not be reflected on the ViewCube in a published DWF™.
Worksharing Monitor (for Autodesk Subscription customers only)
- The Worksharing Monitor tool may behave incorrectly if the Local (or Central) File names
contain dots other than the dot before the .rvt extension.
- Markups made in Design Review with the Freehand Markup tool do not import into Revit with properties.
- Microsoft Office 2007 dictionaries for English, German and Spanish are currently incompatible with Revit. You can still use the provided Autodesk dictionaries or install an earlier version of Microsoft Office to use the older Microsoft dictionaries.

Welcome to the 64‐bit edition of Revit® 2009 platform products. This release takes advantage of the additional memory available to applications in a 64‐bit operating system environment. 32‐bit Microsoft® Windows® operating systems, when properly configured, are limited to providing between 3GB and 4GB of memory to applications. From a software standpoint, there is no practical technical limit to the amount of memory available to compatible applications under 64‐bit Microsoft Windows operating systems, although the hardware platform may impose some technical restrictions on the amount of RAM that may be installed in a given workstation.

Revit 2009 platform 64‐bit product performance is expected to be similar to an identical Revit model edited with Revit 2009 platform 32‐bit products. However, due to the potential for the Revit platform to access greater quantities of memory made available by the Windows operating system running with more installed RAM, the Revit platform may exhibit increased stability.
With hardware configured in the manner listed in the System Recommendations section, it may be possible to edit Revit models of greater size than is practical within the 32‐bit version of the Revit 2009 platform. It should be noted that Revit models whose memory requirements exceed the RAM available in a 32‐bit operating environment may not open in the 32‐bit version of Revit 2009 platform.
Non‐Autodesk external commands and applications designed to access the Revit platform may not be compatible with Revit 2009 64‐bit platform.
As of this Revit release, Microsoft has not made available ODBC (Open Database Connectivity) drivers for its 64‐bit operating systems. Consequently, the Revit 64‐bit platform cannot export a Microsoft® Excel®‐ or Microsoft Access®‐compatible ODBC file.
