I am in the process of converting one of our large workspaces that looked at the saved extents of an ArcGIS Map (.MXD) file and using a CAD seed file, wrote out an AutoCAD .DWG file. The old/original workspace wrote data out to specific layers in that CAD file. It also applied labeling, blocks w/rotations, etc... The end result was a decent looking CAD .dwg that our designers could use as a starting point for a new design project.

My goal is to transition this to an FME Server App and make it a multi-purpose process that would use the Generic Writer and would allow users to select an extent within the FME Server App map and export to the same type of a CAD file, but also if needed, export out a KML, or other formats.

What's the best way to accomplish this? (Writing features out to specific layers withing the CAD .dwg)
