Once you install the add-in, a new tab called RTV Tools will be available in Revit.Ģ. To top it off, you can even schedule to run it overnight, so you are not spending your precious time during the day.ġ. It lets you split the Revit files by levels and then export those levels as Navisworks NWC files. You can get the trial version of this add-in by clicking here. If you are involved in BIM Data Coordination and Clash Detection, this is THE ADD-IN for you. In my quest of finding a better solution, I came across this absolutely awesome Revit add-in that I want to share with you all. Creating section box at each level and then exporting them as NWC files is an extremely tedious process. However, there is an issue in this workflow if you are working on a high rise building. The advantage is that we can then easily run clashes per level so number of clashes found are not intimidating for the users who are fixing them. In fact, in some large projects, I have even recommended creating section box at various levels and exporting the NWC files for those levels. This add-in will replace Revit's built-in IFC exporting model and won't appear as a standalone add-in.For quite a few years now, I have been emphasizing on the advantages of exporting NWC files from Revit for BIM Data coordination using Navisworks.
We have identified several issues with Revit's built-in IFC exporter and the IFCSite is not always exported properly if this add-in isn't installed, which results in inconsistent behaviour when you navigate through the model using various add-ins.
If your workflow relies on IFC, we recommend installing Autodesk's add-in for Revit called IFC 2020 (2019 if you're using Revit 2019 etc.).
Import your NWC file into Navisworks and your model should now be properly positioned geographically. Locate and set the Coordinates field to 'Shared'.ħ. Click the 'Navisworks Settings' button at the bottom of the window.Ħ. Import your Revit file and your model should now be properly positioned geographically.Ĥ. Locate and set the Coordinates field to 'Shared'.ĥ. Ignoring this step will result in inaccurate positioning of the issues recorded by BIM Track.Ĥ. This setting also has to be enabled in Revit (see 3rd Image) when exporting. It is mandatory to have it configured in the file reader options within Navisworks (see 1 st image). You must use a shared coordinate system for your project. Here are a few good practices to keep in mind when setting up your model coordination workflow to enhance interoperability between Navisworks and Revit, ensuring that you get the correct positioning.
