For the people who are trying to convert their AutoCAD® files into Revit®, this is just the first step to making the process that much easier. Due to the fact that Revit, an Autodesk® Product, does not currently read Xclips, Blocks, Or Boundaries set in AutoCAD. You must flatten your files first.
WARNING: This plugin only works if one layer of blocks or clips are used. If multiple blocks are within other blocks, you may need to do additional editing.
