I have been assigned to work on a fit-out project that was coordinated in Navisworks during Core/Shell Construction Phase by the CM. We are in the process of infilling the core and shell on some floors that were left out from the original scope.
So the parameters for my project are

1. Existing (well it is in construction still) Hospital Core and Shell.
2. Major trades have 3D DWG data which was used to coordinate the project during the Core and Shell and few floors that were fitted out.
3. Coordination was done during the construction phase by the CM
4. On the new project as Architects we hold contracts for other diciplines and are responsible for coordinating new and existing work during design phase.

The biggest difference in the original project is the 3D coordination during design phase. Not all partners are using Revit, so we are using Navisworks Manage 2011 to coordinate. This proved to be somewhat challenging as first we could not open any CADDuct solids since they needed an enabler. Earlier (6/14/10) map-software has not released a new enabler to work with 2011. and even after that, with the new download, it refused to work. Or it tried to work and Navisworks would take hours to open a 2mb 3d dwg file. (They have updated the enabler to 9/2010 date, but I am not sure if that works without the work around below. I did not install it as I do not want to break what works)

So now to the error and how to fix it.

Missing object enabler for application Maps_Solids|Product Desc: CadDuct Solids |Company: Micro Application Packages Ltd |WEB Address: www.cadduct.com

I am using Navisworks 2011 (2010 is same fix) on a Windows 7 64 bit.
The new installer would not install the Navisworks enabler correctly. It would copy the files to the correct folder (MapCadduct18x64.dbx, MapsComW18x64.dll) but does not add the necessary Registry Entries.
Step 1:
Download and install the enabler from the website at: CADmep+ & CADduct Object Enabler
Step 2:
Make sure the two files (MapCadduct18x64.dbx, MapsComW18x64.dll) are in the folder C:\Program Files\Autodesk\Navisworks Manage 2011\lcdbx2011. If you are using a DWF File Reader version other than 2011, then you need to have these files in the appropriate lcdbx20xx folder.

Step 3.
Add these registry files, this registry file takes care of 2010 and 2011. If you are using a 2009 reader then you need to change it to 17 and use the 17 dbx files.
CADDuct Navis 2011 Objectdbx 18-181 fix.reg

Reload Navisworks and set the correct File Readers>DWG/DXF>DWG Loader Version to 2011.
Delete the old NWC files and reload your files. Check the scene statistics and enjoy.
