Similar to the ability to link Navisworks models into AutoCAD and ReCap 360 Pro, we now have a new feature in Revit 2018 to add context in the Revit environment from any of the supported file formats within Navisworks. Are you wondering where the NDC file format is?
Like me, you may be seeing initial marketing and technical presentations that list the supported file types to be brought into Revit as NWD and NDC. The NWD is the native Navisworks published file format, but the NDC reference appears to be a mistake.
Looking in any of the Help documents or in Autodesk Knowledge Network reveals no such file type. The reference apparently is for an NWC file, which is the native cache file that Navisworks creates in relation to all file types it loads and uses.
I won’t rule out that maybe something is coming down the line by the NDC name, but I have found nothing that supports that. Aside from this hiccup, the new feature affords us a more streamlined workflow for coordination. Many of us utilize an AEC Collection or Building Design Suite, which includes a Navisworks application, and is an excellent, lightweight tool for reviewing and presenting designs internally or to clients.
This new feature does have limitations, and we need be aware of those. It is intended for viewing models in the context of the Revit environment. Some visual styles are not supported. It will not render, carry over materials, or displays information like it does in Navisworks. If more or less is needed to be displayed, a new export needs to be set up and generated from Navisworks. This is an external link, but it’s managed from its own coordination model dialog, not from the Manage Links dialog.
Visual control is provided by a new tab in the Visibility/Graphics Override dialog. Here, we can control the visibility of the model and edit transparency through an override.
The model(s) will display in our views as a shaded object, so linking for documentation may be a challenge, as Hidden Line visual style is not supported. See the Help documentation for troubleshooting and limitations of linked model display. Even though I will still utilize other Navisworks workflow approaches with my Revit models, such as Switchback, I can see something usable with this new feature and invite you to try it out in your installation of Revit 2018.
