Shading:Overhang is a simple and effective way to shade windows. Open Studio creates an error when reading these in, apparently attemping to convert it to a Shading Group. It doesn't seem necessary ()or even desireable) to make the conversion. OpenStudio should ignore these in the .idf file.
Better yet, maybe there could be a keyword in the comment lines that allow users to force OpenStudio to ignore any given line altogether (this could be used for LOTs of things). I know there are some output issues with this, though. Thanks.
The conversion should work, however we do not need to support both shading group and parametrized overhang
