Light Sources

Drawing files, exported from Revit, can contain light sources, however, they

do not export with the DWG or DXF files. What does get exported is the 3D

mesh geometry representing the light fixture. Therefore, when you import or

link the drawing to 3ds Max, the light object is strictly geometry, not an actual

light source like a spotlight or omni light that you can adjust.

These pieces of geometry are still useful in that you can use them as reference

points for placing and aligning lights you add in 3ds Max.

DXF Files

Along with the ability to export DWG files, Revit can also export to the DXF

file format. The only difference is in how they handle drawings that are linked

(RVT links) to the Revit drawing.

When exporting to DXF, the linked drawings are automatically bound to the

drawing. Therefore, while exporting to a DWG honors the linked drawings

and treats them as AutoCAD xrefs, an exported DXF file will not have xrefs.

Instead, the linked drawings are converted to blocks.

The resulting scene organization will be slightly different when linking or

importing a DXF as opposed to a DWG, but only when RVT links are present

in the drawing.
