The distributable NWC file exporter enables project teams using Autodesk® Naviswork® software to generate whole-project models for simulation and analysis.
Project team members can generate the optimized NWC file directly from their design applications. This capability is provided without necessitating a licensed seat of Autodesk Navisworks 2011 software on the same machine.
The NWC exporter works with a range of products, including the AutoCAD®-based and Revit®-based Autodesk products, as well as Autodesk® 3ds Max®, Bentley MicroStation®, and Graphisoft ArchiCAD® software. The NWC file format supports transfer of both object geometry and associated metadata from the design applications into Autodesk Navisworks 2011 software.
Some customers experience "rips", "tears" or another anomaly in the model when using the Render or Export Rendered Image functionality.
It should also be noted that the problem does not go away, once it has started. Even if the file is closed and renewed attempts are made.
This may be due to missing geometry when rendering large models, particularly models with a very large ground plane or large 3D space. This is a known issue and related to the rendering engine used in Navisworks.
Here's the one workaround that seems to have resolved the majority of cases. Improve your Render performance by hiding geometry (CTRL-H) that is unused in your view or unrelated.

Our licensing team has posted two new updates to the product support site.
This Hotfix repairs a problem that occurs during the side-by-side installation of two different licensing products. During the installation of stand-alone licensing products with previously installed network licensing products, an error occurs indicating that the installation failed.
You can find the Hotfix and additional information here
You configured a machine to be a network license server and then installed an Autodesk product on the same machine. When you launch the product, it tries to check out a network license and fails.
On Windows, the FLEXnet Finder dialog displays and, when dismissed, is followed by a license error dialog displaying the error code [-15.570.36]. In the Mac OS, a license error dialog displays the same error code but it does not display a FLEXnet Finder dialog.
This happens on all operating systems where an IPv6 stack is installed.
You can find the solution and additional information here.
Please let us know should the above solutions not resolve stated issues for you.
My recent post "What is Clash Detection" triggered some customer feedback, one of which I consider worthy covering in this article.
Here is the question submitted by the reader: "Is there any way to get the various reports to list a Revit's model's Element ID of a clashing object?"
Very happy to share that we can answer the question with "Yes it is possible".
Users need to set up "Smart tags" to show the element ID. "Smart tags display property information in a tooltip style window as you move your cursor over objects in the Scene Area. By default, smart tags show the name and type of the object, but you can use the Options Editor to define which properties are shown. Each definition that you configure enables you to display an additional category/property combination in smart tags. You can choose whether to hide category names in smart tags or not."
Then export the report as normal and the Element ID should appear in the report.
Please share any feedback, comments or suggestions you may have.
"Clash detection allows for the effective identification, inspection and reporting of interferences in a 3D project model."
Navisworks use the Clash Detective tool for to permit clash detection. It can help you to reduce the risk of human error during model inspections. It can also be used as a one-off 'sanity check' for a completed design work, or it can be used as an ongoing audit check of the project.
You can conduct clash tests between traditional 3D geometry (triangles), and laser-scanned point clouds or you can combine the Clash Detective functionality with other Autodesk Navisworks tools:
Clash Detective also allows you to create custom clash tests via Exported clash tests. If you have a common set of clash tests that you reuse on multiple projects, you can turn them into a custom clash test. Once installed as a custom clash test, the entire batch of tests can be selected and run directly from the Select Tab. The results from all tests in the batch are combined and presented as the results of the custom clash test. The name of each test in the batch is displayed in the Description field of the results.
Custom clash tests are an excellent way to roll out a standardized set of tests across an organization. They allow the expertise of "power" users to be reused by everyone. Finally, they can be seen as a way of implementing object intelligence. For example, a custom clash test could be written that checked for compliance with a local building code based on object information and properties defined in a particular CAD system.
And last, but not least - there is report functionality. For instance, you may need a report that will enable planners to adjust the project schedule in their 3rd party scheduling software.
For time-based clashes, it may be helpful to include in the report additional information about each static package in the clash. This information can be set up in the Options Editor by using the Smart Tags definitions.
As always, please share any feedback, comments or suggestions you may have.

Some of you may have experienced the display of wireframe graphics (bounding boxes) of ducts, pipes or similar during opening of a DWG file in Navisworks Manage.
Some applications based on the AutoCAD® platform (including Autodesk products such as AutoCAD® Architecture, and non-Autodesk products such as Bentley AutoPLANT) generate custom objects, which are then saved in the subsequent DWG file.
In order to properly display the geometry and access the properties of these custom objects, you must have the corresponding Object Enabler (OE) installed on your computer. You can obtain the necessary Object Enablers from the manufacturers of these applications. For example, the Autodesk Object Enablers are available from the following webpage:
Follow these steps to display custom objects:
Note: When using some OEs (for example, AutoCAD Architecture, AutoCAD MEP, AutoCAD® Civil 3D®, and other OEs based on these) the display of the geometry in Navisworks depends on the display configuration in use when the DWG file was saved. For example, if a model was saved in a wireframe view in the AutoCAD-based application, it will appear as wireframe in Navisworks. To change this behavior:

Many of Autodesk's applications, including Navisworks, are able to take advantage of the 3GB functionality switch.
Advanced users may know that the virtual address space of processes and applications is still limited to 2 GB unless the /3GB switch is used in the Boot.ini file. When the physical RAM in the system exceeds 16 GB and the /3GB switch is used, the operating system will ignore the additional RAM until the /3GB switch is removed. This is because of the increased size of the kernel required to support more Page Table Entries.
Note: Only applications that use IMAGE_FILE_LARGE_ADDRESS_AWARE in the process header can take advantage of this functionality.
Enable the 3GB switch on Windows XP
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP Professional" /fastdetect
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP Professional 3GB" /3GB /fastdetect
Note: Do not overwrite any existing lines.
Note: If problems occur during startup, you may need to update some of your drivers.
Enable the 3GB switch on Windows Vista
Disable the 3GB switch on Windows Vista
For more information on the 3GB switch, refer to the following Microsoft MSDN article:

Users of Navisworks Manage may have experienced a technical problem, where the application opens slowly, misses toolbars once started - or locks up all together on start up .
These or similar issues can occur if the Navisworks session file, "lastsession.xml", has been corrupted.
Corruption can present itself due to several reasons, but is mainly due to premature system termination or the incorrect closing of files.
Usually the problem can be resolved by simply renaming the Navisworks session file.
This can be achieved as follows:
1. Exit Navisworks
2. Use Windows Explorer and navigate to the folder associated with your operating system:
Microsoft Windows Vista- C:\Users\<UserName>\Appdata\Roaming\Autodesk Navisworks
3. Rename the "lastsession.xml" file
4. Upon restarting Navisworks, a new (default) version of the "lastsession.xml" file will be created
Please let us know whether this failed to resolve your problem or whether you have any other feedback for us.
