Vincent:
Thanks for the response. I will give it a try later. As for your questions;
This is the first project I've tried, so no it hasn't been happening to any other files.
Nothing has been displayed in the scene graph.
I was searching through the site earlier and wanted to know if I could import a NWC from Navisworks and it appears that's another option. (Not preferred). To confirm that option, I would have to export it via directlink exporter? Will let you know how things pan out.
Thanks
