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.

In this section, you'll find some recommended settings that you can use when linking or importing your DWG files. These settings are found on the Basic File Link Settings dialog on page 6998, the Advanced File Link Settings dialog on page 7002, the Spline Rendering File Link 7036 | Chapter 23 Managing Scenes and Projects
