2 On the OE Setup page, select the check box for the relevant 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 you’ve installed OE for AutoCAD Architecture 2007, you must set the DWG
Loader Version to ‘2007’.
When you open a DWG file in Autodesk Navisworks, the file reader uses the configured OE.
Quick Reference
How do I know if I need to use an Object Enabler with Autodesk Navisworks 2011?
When a DWG file is opened in Autodesk Navisworks 2011, and the objects are displayed as wireframe geometry,
it usually means that an Object Enabler is missing.
Additionally, the Scene Statistics dialog box reports any missing or failed to load OEs.
Where do I obtain Object Enablers from?
The recommended way to obtain OEs is to request them from the persons authoring the DWG file. This ensures
that the correct version of OE is used.
TIP You can also download many OEs from the vendor websites for the authoring applications. For example, you can
download Autodesk OEs from http://www.autodesk.com/oe.
What do I do when Object Enablers are not reported as missing but I can only see wireframe geometry?
