Can you export your Revit model to a 3D FBX file for rendering?
Short Answer
Yes — in Autodesk Revit, you can export your Revit model to a 3D fbx file for rendering by using FBX Export from the active 3D view. This is the most common professional method for sending geometry and materials to rendering tools like 3ds Max. A key limitation is that export quality depends heavily on the current view and visibility settings.
What You Need to Know Before
Warning: Revit exports FBX from the active 3D view, not necessarily the full model database. If categories, linked models, detail level, or temporary visibility settings are wrong, your rendered FBX may export incomplete or look very different from what you expected.
How to Export Revit to 3D FBX
Command: FBX Export
Shortcut: None by default
Quick Steps:
- Open the correct 3D View in Revit, then verify Visibility/Graphics and Detail Level on the view control Bar.
- Go to File tab > Export > FBX.
- Choose the save location, export the file, and use that FBX in your rendering application.
Variables & Settings
Key Setting: Detail Level in the active 3D view
Expert Setting: Detail Level controls how much model geometry is exported. If set to Coarse, simplified objects may export; if set to Fine, more detailed components and geometry are typically included, which is usually better for rendering but can increase file size.
Why it Fails
- Cause 1 (Geometry): The model is exported from a 3D view with a section box, hidden categories, or coarse detail, so elements are missing or simplified.
- Cause 2 (layers/Locks): Linked Revit models or imported files are not visible in the active view, so they do not appear correctly in the FBX.
- Cause 3 (Command/Logic): FBX export is view-based in Revit, so users expecting a full model export without checking the source 3D view often get incomplete results.
Quick Fix & Best Practice
- Quick Fix: Create a dedicated 3D export view, turn on required categories in VG, set Detail Level to Fine, and disable any unwanted Section Box before using FBX Export.
- Manager’s Verdict: Use FBX when sending revit geometry to downstream rendering workflows, especially with Autodesk tools. Avoid it for data-rich BIM exchange; use it mainly for visualization, not model intelligence.
FAQ
Can revit export FBX directly?
Yes, Revit includes a built-in FBX export option.
Does Revit export materials to FBX?
Yes, but material translation can vary depending on the rendering software.
Why are objects missing in my exported FBX?
They are usually hidden, cropped, or excluded in the active 3D view.
