Thankyou for the reply. I am having trouble seeing the screenshots (they are too small), but I will try to work through it as best I can. We are running AutoCAD 2012, I am not sure if that will make a difference.
Navisworks caches the dwg file to a nwc file and then uses only the nwc file. You must remove the nwc file.
Then Navisworks uses the prostructures.dbx to open the dwg and to cache it.
I have Navisworks 13 but I forced it to use the 18.2 dbx Loader. Dwg Loader Version is set to 2012.
Can be set with Global options.
AutoCAD 2013 needs a Service Pack 1.1 to load ProStructures Dwgs.
Same for the RealDwg 2013 as I can see with Bentley MicroStation SS3.
I guess a Service Pack 1.1 for NavisWorks 2013 will be offered by Autodesk later.
The AutoCAD object dbx entry for Pro_Stahl_App points to the Navisworks folder.
I have the AutoCAD objectenabler (objectdbx) key and the Navisworks objectdbx key set up.
Please look at my screenshots and try to reproduce.
Before installing Select series 5, Navisworks (2012 and 2013) read Prostructures objects without problem. Now I can't view those items at all.
What things should I be trying to get this working again?
