JTB XClipClean 2.0 is now released. A few bugs have been fixed and there is now installer available.
JTB XClipClean is an Xclip-cutter app for AutoCAD to clean up xrefs or blocks that been clipped so that the information that is outside the clip is removed. This is useful when you need to remove hidden geometry and minimize DWG file size. AutoCAD allows blocks and xrefs to be clipped using the XCLIP command. Sometimes for different reasons you have to clean up the blocks or xrefs that have been clipped. JTB XClipClean can help you with that by deleting and trimming geometry that is outside the xclip boundary.
Revit does not handle xclipped blocks and xrefs so XClipClean can be useful to run on drawings before taking them into Revit.
