Proper setup of Object Enablers

[RobertB]

I see many questions related to getting object enablers working properly in NavisWorks 2009.

Here is the correct procedure for supporting AutoCAD MEP 2008. The steps will be similar for other AutoCAD products.

Install the Object Enablers
Object Enablers for NavisWorks
Note that the ACA OE is required to support the AMEP OE!

1. Install the AutoCAD Architecture 2008 OE (must be installed first)
2. Install the AutoCAD MEP 2008 OE

Set the loaders for DWG in Tools, Global Options

1. Start NavisWorks and go to Tools, Global Options, File Readers, DWG/DXF/SAT
2. Set DWG Loader version to 2008 (If you are supporting other versions, set appropriately.)
3. Close Navisworks

Clear existing cache files
Cache files will reload the bad representations unless the drawing is more recent than the cache file.

1. Delete any existing .nwc files

This information is finally documented by Autodesk, but apparently is only available to Subscription customers. I've included this link for Subscription customers.
