NOTE Autodesk Navisworks contains versions of RealDWG
for 2005, 2006, 2007,
2008, 2009, 2010, and 2012. This means you can use OE between 2005 and 2012
with Autodesk Navisworks. You cannot use any OEs older than 2005. However,
OEs are backwards compatible, and you can install a later OE to support reading
of older versions of DWG files.
To check if an OE is required
1 In Autodesk Navisworks, open a DWG file.
2 If you can only see wireframe geometry, click the Home tab, slide out
the Project panel, and click Scene Statistics. The Scene Statistics
dialog box contains the report listing any missing, or failed to load OEs.
You need to install all missing OEs to open the file correctly in Autodesk
Navisworks.
NOTE Occasionally, an OE is already installed, but does not support
non-AutoCAD-based applications, like Autodesk Navisworks. In such cases,
the OE is reported as missing in the Scene Statistics dialog box.
To install and use an OE with Autodesk Navisworks
1 Obtain the required OE, and run the installer.
2 On the OE Setup page, select the check box for the relevant Autodesk
Autodesk Navisworks products.
NOTE Some OEs have dependencies on other OEs, and, therefore, must be
installed in a specific order. For example, the AutoCAD MEP 2009 OE has a
dependency on the AutoCAD Architecture 2009 OE. As a result, the AutoCAD
MEP 2009 OE must be installed after the AutoCAD Architecture OE.
3 Click Install. When the OE is installed, click Finish.
4 Run Autodesk Navisworks.
5 Click the application button
Options.
6 In the Options Editor, expand the File Readers node, and click
DWG/DXF.
7 Ensure the value in the DWG Loader Version field is the same as the
version of the installed OE, and close the dialog box. For example, if
youve installed OE for AutoCAD Architecture 2007, you must set the
DWG Loader Version to 2007.
