We are pleased to announce that as a result of ongoing collaboration between Autodesk Navisworks® and Intergraph CADWorx® development teams, CADWorx 2013 Plant Professional models (including intelligent CADWorx properties) will now be supported in Navisworks, beginning with version 2013/SP1. See Autodesk announcement here: http://beyonddesign.typepad.com/posts/2012/06/service-pack-1-now-available-for-autodesk-navisworks-2013.html
You can download the latest version of Autodesk Navisworks 2013 Service Pack 1 here: http://usa.autodesk.com/adsk/servlet/ps/dl/item?siteID=123112&id=19840757&linkID=10382102
If CADWorx 2013 is not already installed on the same machine as Navisworks you will need to install the CADWorx 2013 object enablers on each machine with which you wish to view CADWorx 2013 models. The enabler can be found here: http://icas.intergraph.com/forms/ICAS-Downloads
Please note that after installing Navisworks 2013 SP1 users will need to make one quick change to the default settings to make it work properly with CADWorx 2013 models. Please read the following or view this short video Download Navisworks 2013.wmv (922.3K).
1) Start Navisworks 2013.
2) Select the file button.
3) Select the options button.
4) Then select File Readers, DWG/DXF, change the DWG Loader Version to 2012, and select Ok.
Now Navisworks 2013 will be able to open a CADWorx 2013 model, visualize the CADWorx solids, and view the CADWorx intelligent Xdata.
