Known Issues with This Update

• After installing this update you may receive a "Error Code: 3010" message incorrectly claiming that the update failed. You can verify this by viewing installed updates through the Windows control panel.
• After you apply this update, you may experience the following ribbon customization-related problems:

An Incorrect or Missing Ribbon Tab

• Known Issue: When you display a ribbon tab from a partial or Enterprise CUI file, on the ribbon, the ribbon tab displays incorrectly or is missing.
• Workaround: To correctly display a ribbon tab, recreate the workspace used to display the ribbon tab from scratch. Do not duplicate or attempt to update the workspace. Once you create a new workspace, set the workspace current. The ribbon tab should display correctly.
• For a partial CUI file, before you add a ribbon tab to a workspace, use the Customize User Interface (CUI) Editor to change the customization group name of the file. The customization group name is represented by the uppermost node of the tree in the Customization In pane.

A Blank Image for a Command

• Known Issue: On a ribbon panel, the image associated with a command defined in the Command List pane displays as a blank icon.
• Workaround: To recreate a ribbon command item on a ribbon panel, delete it. Then, from the Command List pane, add the command to the ribbon panel.

"In every single test I threw at the Revit Structure for the 64-bit system it beat the 32-bit system," said Ken Murphy, BIM manager, Thornton Tomasetti. "On average, we observed approximately a 20 percent performance gain on operations such as saving files and exporting models to other formats for outside consultants. And when it comes to rendering images of large project models, such as an American football stadium with thousands of members, we saw up to a 50 percent performance improvement over the 32-bit platform."

"With 64-bit Revit Architecture we can completely load a very large project into a session and work on it at one time; and that is something that represents a significant efficiency improvement over the 32-bit environment," said Lonnie Cumpton, Revit task force manager for the Friedmutter Group. "For example, we have a large project that consists of 2.9 gigabytes of Revit data contained in 22 individual files. With 64-bit Revit Architecture we can link all the pieces together into one big model and cut an entire building section to gain an understanding from a section elevation standpoint of the entire project at one time. Using 32-bit Revit Architecture we'd have to cut individual pieces of sections in each model and then piece them back together. It took us a day to do that. Now we can do it in less than an hour."

"We've been beta testing the 64-bit Revit Structure software and the increases in efficiency and productivity are impressive," said Jamie Richardson, Associate & CAD manager, Ericksen Roed & Associates. "Cutting sections and switching between views is much faster. Moving within the views and rotating the model in a 3D view is also noticeably faster and smoother. With what we have seen in our beta testing, and what we're hearing from users testing the beta on their current projects, we see no reason not to go to the 64-bit version of Revit Structure."

Performance
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.

Model Size
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.

AddIns
Non‐Autodesk external commands and applications designed to access the Revit platform may not be compatible with Revit 2009 64‐bit platform.

Limitations
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.

Web Update #2 is not a full install; rather it is using Service Pack technology similar to AutoCAD based products. Prior to installing the Web Update #2 Service pack, please verify that you have already installed the First Customer Ship build or Web Update #1 build of Revit MEP 2009.
