Revit: How do I export a model from Revit to Lumion?
The best way to export Revit
models to Lumion
is via our dedicated, free Lumion Plug-in for Revit

For Revit LT you can't use the plug-in and should use the built-in DWG exporter instead. Please note that textures are not transferred correctly from Revit LT to Lumion due to AutoDesk limitations in the exported DWG file.
Make sure you click here
and install the DWG to Lumion Bridge
Please also ensure that during export you selected an option "Export all properties BYLAYER, and create new layers for overrides". See video tutorial below:Alternative method:
Alternatively, if you have 3D Studio Max installed, you can use this method:
- Export an FBX
file from Revit
- Import the FBX
file in 3D Studio Max
- Prepare and export the model as described in this post
- Import the Collada
(DAE) file in Lumion

If you select option Skip Interior Details
then these Revit Categories are skipped:

There are two axis systems in Revit projects:
- Base Point
: Internal axis system.
- Survey Point
: Axis system based on a geodetic survey.
In Revit, you can mark the Base Point
and Survey Point
in your project. The Revit to Lumion Bridge
exporter settings let you define whether you want the Base Point
or the Survey Point
to become the insertion point in Lumion.
Support for True (Geographic) North (RTLB version 1.5 and later):
Why can't I assign a Lumion material to individual surfaces?
- If you choose "Base point" as insertion point, then project north is taken into account.
- If you choose "Survey point" as insertion point, then true north is taken into account.
Lumion will always combine surfaces that use the same material in Revit
. If you want to assign a Lumion material to a specific surface, you must
assign a unique material to that surface in Revit
before exporting the model.How do I update the model in Lumion after making changes to it in Revit?
Use the Re-import model
function in Lumion.What Does the Geometry Optimization setting do?
Before the plugin exports an object from Revit it needs to tessellate it (divide the model in to triangles).
But the default built-in Revit tessellator has a problem with thin, long objects (railings, frames etc). It generates too many triangles.
If you turn on Geometry Optimization
then, only for the given object categories, the exporter tries to tessellate it differently to get optimal smoothing with minimal triangles, instead of the built-in tessellator .
However, occasionally there is a drawback:- sometimes UVs are incorrect.
It's better to avoid this option, unless your Scene generates too large a DAE file (after reducing it using lower Smoothing Accuracy
