If there are texture maps in the model, be sure to include those with any files sent to a 3D modeler. This could be problematic if the files are large- the merged file may be too big to handle. The export to DWG allows a conversion to a DWG with linked XRef files- all of the individual reference files are converted separately or the references can be merged into one single DWG at export time. The safest method is to convert all files separately and then re-assemble in the final 3D model. Reference files can be a particular problem during conversion. This will ensure that these polygons are converted to faces. Under ' Cap Closed Polygons' set to 'always' or 'when 3D'. When you have the 'Save As' dialog open, select the options button, and select the ' Advanced' tab. For export to DWG, there is a setting in the options dialog that must be set to ensure that all polygons are capped. At a minimum, an organized list of level numbers and their contents is useful.ДЄnother key issue when exporting models to other rendering applications is the correct surfacing, or 'capping' of polygons. Objects with logical names save an immense amount of time and effort on the final production end. AutoCAD DWG files can be imported directly into 3D Studio Max without going through another conversion step. They can easily be remapped to layers with names in the new file, the names on the layers are then passed on as object or group names in the 3D Studio Max file. This feature is useful if the levels are left in the original numbered format. There is an option in the Save as dialog for DWG to remap level names to specific layer names in the AutoCAD file. In the case of export for 3D Studio Max, the most efficient method is to save the model directly as a DWG file (Microstation V8), where the default is to pass on level naming to layers in the DWG. In most cases, level names are the only information passed on with the geometry. Much of this organization is defined in FLHD CAD standards for standard elements, but as new elements are created for 3D models, it is essential to use descriptive naming of levels for convenient export. The first is good organization of the level structure and naming conventions. There are two key things to keep in mind when preparing models for export to outside 3D applications. This section discusses issues with exporting 3D Microstation files to other rendering programs, as well as some of the visualization techniques possible with those programs.
