Conversion of igr files to dwg file format

Intergraph SmartSketch diagram and technical drawing software supports several CAD formats, including the DWG, to which it can export its own IGR drawing designs, which is what igr to dwg conversion typically represents. It doesn't look like that any other program supports the IGR format, so it is probably your only choice if you need to convert igr to dwg.
