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.
