Convert .dc files to .dwg

Please can anyone help by telling me how I can convert .dc files to dwg for free!

I’m not certain but I think that this is an Imsi DesignCad file. You could try downloading the free Imsi DoubleCad which may be able to open it:

If that doesn’t work you could always try downloading a trial version of DoubleCad and also possibly Turbocad, which I think can also open .dc files.Do a search on the respective web sites for download instructions.

Once you find the programme that can open it, then simply do a ‘save as’ to convert to DWG.
