Trying to open (import) a .OBJ scene into the Autodesk 123D application, it displays a warning sign and the error: "Input string was not in a correct format".

The problem may be in the decimal number delimiter on non-English operating systems (locale). Either change your Windows settings - set the decimal delimiter from comma (",") to point ("."), or edit your OBJ file (e.g. in Notepad) and globally replace all point characters with commas.
