I have a Revit 2021 model which has been developed to a schematic design level, not very heavy or complex. Side note, the Revit file is in the Imperial unit system (feet).
We modeled the exterior wall in Rhino, and pulled it into Revit using Rhino Inside, back spring of 2021. The Rhino file is modeled in inches (in case it is important). I’ve
However, now, when I try to open the rhino file using Rhino Inside, it consistently crashes. I’ve tested the following scenarios:
- Open Revit model, launch Rhino Inside, open rhino model. “Model units mismatch” prompt comes up. Choose not to scale the model. Revit Crashes.
- Open Revit model, launch Rhino Inside, open rhino model. “Model units mismatch” prompt comes up. Choose to scale the model. Revit Crashes.
- Open Revit model, create new project. Launch Rhino Inside, open rhino model. “Model units mismatch” prompt comes up. Choose not to scale the model. Revit Crashes.
- Open Revit model, create new project. Launch Rhino Inside, open rhino model. “Model units mismatch” prompt comes up. Choose to scale the model. Revit Crashes.
- Open Revit model, create new project. Launch Rhino Inside, open rhino model. “Model units mismatch” prompt comes up. Wait a few seconds without clicking on anything. Revit Crashes.
I’ve purged the model, and audited it:

As a final attempt, I tried cutting and pasting half of the Rhino file’s contents over to a new rhino file. This worked! Both halves of the original file now open. Any thoughts on what may be causing this? Is there a maximum file size for Rhino files?
Original (old) model file: 489,862 kb
Old model file with stuff cut out: 88,747kb
New Model file with stuff pasted in: 401,709kb
