Conversion of pl1 files to pl2 file format

Both .pl1 and .pl2 files are used by 3D Home Architect, which means pl1 to pl2 conversion can be most likely done with the software. It might be related to cases of resaving between different versions of 3D Home Architect files and that is typically done through standard File / Save as.. function.
