IRM supports importing drawing data from CAD systems using the DWG, DXF, and DGN file formats. IRM's CAD file import feature supports 2D drawing data only, for purposes of showing floorplans and siteplans in Areas.
The process of importing CAD file data using IRM provides considerable flexibility. This section will help the user to understand the process and the options available when importing CAD files into an existing Area in the Design World.
