Certain Z+F files containing laser scan data will cause Autodesk Navisworks to crash. The hot fix installer distributes an up-to-date version of the Z+F DLL (www.zf-laser.com) used by Navisworks to read Z+F files.
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.
FLEXnet Licensing Side-by-Side Hotfix
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
Failure to check out a license when running a network product on the same machine as the network license server
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:
Linking Clash Detective and Object Animation together gives you the ability to automatically check interferences between moving objects. For example, linking a Clash Detective test to an existing animation scene would automatically highlight clashes for both static and moving objects during the animation, for example, a crane rotating through the top of a building, a delivery lorry colliding with a workgroup, and so on.
Linking Clash Detective and TimeLiner together enables the time-based clash checks on the project. See Select Items for Testing for further details on time-based clashing.
Linking togetherClash Detective, TimeLiner, and Object Animation enables clash testing of fully animated TimeLiner schedules.
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:
Open the file that contains the proxy graphics in Navisworks.
Click View menu > Scene Statistics. A list of the missing Object Enablers will be displayed.
Locate, download, and install the missing Object Enablers from the manufacturer's website. Important! Some Object Enablers have dependencies on other OEs, and, therefore, need to be installed in a specific order. For example, the AutoCAD® MEP 2009 OE has a dependency on the AutoCAD Architecture 2009 OE. Therefore, you must install the AutoCAD Architecture OE before installing the AutoCAD MEP 2009 OE. Also, be aware that some OEs may not be designed to work with non-AutoCAD-based applications, such as Navisworks. In these cases, the OE may already be installed, even though it was listed as missing in the Scene Statistics dialog box, or it may cause the application to crash when used.
Click Tools menu > Global Options > File Readers > DWG/DXF/SAT.
From the Loader for DWG drop-down menu, select the year that corresponds to the DWG year of the file. Note: Depending on the OE, you may also need to change the Render Type from Automatic to Shaded.
Delete any NWC (cache) files associated with your DWG file. A new NWC file will be created when the model is reopened.
Start Navisworks and open the DWG file.
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:
In Navisworks, click Tools menu > Global Options.
In the Options Editor, click File Readers menu > DWG/DXF/SAT.
Select the Use ADT Standard Configuration check box.
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
Right-click My Computer. Click Properties.
In the System Properties dialog box, click the Advanced tab.
On the Advanced tab, under Startup and Recovery, click Settings.
In the Startup and Recovery dialog box, under System startup, click Edit. The Windows boot.ini file will be opened in Microsoft® Notepad.
Create a backup copy of the boot.ini file. Note: Boot.ini files may vary from computer to computer. Select the following line in the boot.ini file:
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP Professional" /fastdetect
Press Ctrl+C to copy the line and then press Ctrl+V to paste it immediately below the original line. Note: Your text string may be different from the text string in this solution, so be sure to copy the text string from your boot.ini file, and not the text string included here. Modify the copied line to include “ /3GB”, as shown in the following example:
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP Professional 3GB" /3GB /fastdetect
Note: Do not overwrite any existing lines.
Save and close the boot.ini file.
Click OK to close each dialog box.
Restart your computer.
During startup, select the 3GB option. If you do not select the 3GB option, the system will default to the 2GB total memory setting.
Note: If problems occur during startup, you may need to update some of your drivers.
Enable the 3GB switch on Windows Vista
Right-click Command Prompt in the Accessories program group of the Start menu. Click Run as Administrator.
At the command prompt, enter "bcdedit /set IncreaseUserVa 3072"
Restart the computer.
Disable the 3GB switch on Windows Vista
Right-click on Command Prompt in the Accessories program group of the Start menu. Click Run as Administrator.
At the command prompt, enter "bcdedit /deletevalue IncreaseUserVa"
Restart the computer.
