Hi there,

I amt trying to run Naviswork via Dynamo, similar to Dynawork node. I need to do this to add some customized options to it. I can successfully run it from Visual Studio as a C language program. Though, when I try to do the same w.r.t. Python it is giving me an error: ‘Autodesk’ no defined. Any suggestions?

nwapp = Autodesk.Navisworks.Api.Automation.NavisworksApplication();

doc = nwapp.ActiveDocument

OUT = doc

You are trying to import the Navisworks and Revit api, but if it fails just passing onto the next aspect of the code. Instead you need to surface the error, or simply remove the try/except statement (which is the preferable option in my opinion).
