Overview of Object Enablers
Object Enablers (OEs) can be thought of as a ‘translator’ for custom objects.
Applications based on the AutoCAD
®
platform, (including Autodesk products
like AutoCAD
®
Architecture, and non-Autodesk products like Bentley
AutoPlant) generate custom objects that are saved into the DWG file format.
These custom objects are typically found in content libraries that are built
into these applications.
Many applications have the ability to read DWG files; however, outside of
the authoring application any custom objects cannot be interpreted. As a
result, DWG file readers display such custom objects incorrectly, as proxy
graphics (wireframe geometry), unless the required OE is installed on the
machine reading the DWG file.
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.
