I have just purchased Home Designer Architectural so that I can design my new vacation home. I have had a site survey done 2 years ago and have a DWG file of my lot, but am not able to load this into Home Designer, only .txt of .gpx files. The tutorial says that there are 3rd party programs for converting a .dwg into either acceptable format, but I have not been able to find one. Does anyone know how to convert a .dwg to a .txt or .gpx on a mac, preferably free? Thank you.
