CHAPTER 2 Files and File Types
Anytime you load a DWG-based file with custom objects, Navisworks will require an object
enabler to display the geometry properly. This requirement tends to be consistent for most DWG
files generated in applications other than standard AutoCAD. Your scene statistics will also indi-
cate whether any object enablers are missing in your model.
You can access the Scene Statistics dialog box by doing the following. In the ribbon, navigate
to the Home tab and, in the Project panel, select the drop-down arrow, as shown in Figure 2.28.
Navisworks opens the Scene Statistics dialog box. If object enablers are missing from the
current scene, they will be recorded in the list along with which file they are missing from
(Figure 2.29).
Locating and Configuring an Object Enabler
Object enablers can usually be located from the appropriate software vendors. For Autodesk
products, the object enablers can be found here: www.autodesk.com/oe.
Selecting object enablers can be a little tricky. When downloading the object enabler, choose
the enabler that best matches the program you wish to view the file with. For Navisworks, this
will be vanilla, or plain AutoCAD. As you’ll recall, Navisworks can view DWG files without any
custom objects, so you want to create a translator that allows AutoCAD to view those files. In
turn Navisworks will also be able to view those files.
