DWG Not Importing

To anyone who can help,

I'm attempting to display a 3D drawing exported from Revit. The file is a 27.2 MB drawing. Is it too large to import into Nubigon? When I go through the import steps, the loading bar is displayed but the drawing does not show up in my object list.

Other drawings will show up for this project, however (CAD drawings).

I haven't had this problem before when trying to import 3D DWGs. What am I doing wrong? I would attach the file below but it is too large to attach, which makes me think it's too large to import into Nubigon.

Hi Hunter, there is no file size limit. 

The Autodesk DWG specifications set a limit of 32676 faces/vertices for polyface meshes in a DWG file. Currently, you won’t be able to open files containing polyface meshes beyond this threshold. We will address this issue with our fall 2023 release. 

This issue typically arises with DWG files containing terrains with many faces. Try removing such meshes from your DWG file or exporting them as solids as a temporary workaround.
