I guess i lost my faith in finding solution to this.
Is there a way to export Revit items from the Revit file to specific layers in AutoCAD in the case if i have Public Library and I want to export this projector to AutoCAD, but provided that the chairs are sorted by a special layer within the files of AutoCAD and offices with a special layer and shelves with a special layer …
In other words, I want to create AutoCAD layers according of Revit type or the Parameter ?
Unless you implement a custom export process and write the DXF/DWG yourself, I think your only other alternative is to tinker with the default export settings:
Try adding one of the available modifiers and see if that helps differentiate elements. For example use Dynamo to add each type to a different workset (bad bim >.<), name the workset after the type name add the {Workset} modifier to the desired category.
