We know there other methods you use to pare down your files - please get in touch if you feel there's any that you can't live without that we should include in this article. As with any memory hungry operation, try to minimize the number of other programs competing for resources.If you still have problems and the machine has been left on for days or weeks then a restart of the machine may also be a good idea. Save the project, restart Revit, reopen the file and try to export. Does Revit needs a restart? If you are working in the application all day and then try to export at the end of the day, you have been potentially caching your project all day.Other things to check if you still have problems exporting NWD files viewed with Navisworks Freedom give stakeholders equal access to explore and experience. After all individual linked models have been purged, purge the main model and try again to export. C exports two routines by default: a constructor. You may want to open each individual linked file and purge it until there is nothing left to purge this may take two or three passes. You will be able to select which items are Purged before proceeding. I do not see a way to change the material of a specific Fabrication parts system.You can use the 'Purge Unused' button on the Manage tab of Revit to delete unused families or unused family types from the model. I think the only true way as of right now is to use Dynamo code to find the systems and color them accordingly so that when you export to NWC, the colors get exported also. If its a collaborated model, no one else will see the colors you just set up. In the end it did work, but this is still not the proper way. Trying to find the correct Category and Property was a pain in the butt. Share your knowledge, ask questions, and explore popular Revit Architecture topics. This took some time to figure out since you have to setup Selection Sets. Import your NWC file into Navisworks and your model should now be properly positioned geographically. Locate and set the Coordinates field to 'Shared'. I did get the colors working using the Appearance Profiler. Click the 'Navisworks Settings' button at the bottom of the window. When you have to do this (Export to Navis) more than 20 times a day, this definitely lags the process. This seemed like a real hacky way and added quite a few extra steps. I didn't have time to mess with the files after exporting to get them to color inside Navis.
