Curved Wall Coordination is sometimes tricky. In this blog, you will learn how to change the settings in Revit so that your curved wall will appear as intended for Coordination in Navisworks or BIM 360 Glue.

If you're working on a project that requires LOD 400 design quality for curved wall or shape coordination, then you've likely noticed that straight out of the box, Revit doesn't export a curved line to Navisworks or Glue as well as Rhino or other 3D modeling software does. Here's how to close the gap on that issue:

Change your DWG/DXF Export Settings

Here's how to change your DWG/DXF Export Settings:

  1. Open your file in Revit & navigate (or create) to a 3D view that you want to export to Navisworks.
  2. Select File > Export > Options.
  3. Select "DWG / DXF Export Settings"
  4. When the DWG / DXF Export settings window pops up, navigate to the Solids Tab.
  5. Select ACIS solids instead of Polymesh

This will give your models that you export as DWGs curved lines that match nicely with Rhino, and will show up in BIM 360 Glue or Navisworks as a more curved line.

In the DWG/DXF Export Settings, select the Solids menu, then change the button from Polymesh to ACIS. In the DWG/DXF Export Settings, select the Solids menu, then change the button from Polymesh to ACIS.

Change your Navisworks Export Settings

Exporting as a DWG is the best solution, but if that isn't possible, or if you've already started exporting to Glue or Navisworks with NWC files, then this solution may work for you as well. Here's how to change your Navisworks Settings:

  1. Open your file in Revit & navigate (or create) to a 3D view that you want to export to Navisworks.
  2. Click on the Add-Ins Tab & select External Tools (should be on the far left).
  3. Select Navisworks
  4. When the "Export scene as..." window pops up, click the Navisworks Settings... button at the bottom.
  5. Navigate to the File Readers & select Revit.
  6. Down near the bottom, there's a window that says, "Faceting Factor." Change the number to a larger number.
    1. Autodesk suggests changing it to 5 or 10, but when I did it I made it a much higher number like 50. It didn't appear to significantly affect the export time or file size of the exported file.
