The reason that VoloView will not work with the newer ACAD files is that Autodesk now encrypts all of it's files. What used to be as easy as reading the fileheader of the DWG, and determinig what to draw and where is now not that simple. Now, you need to decrypt the file first, then you can extract what you need from the file to do the drawing. Autodesk has gone through and said that this encryption was a compression function. But, from what I heard, this is a lie. Regardless, because of the DMCA, it is questionable if it is legal to reverse-engineer the file structure. So I doubt that VoloView or anyone else out there will put out an OCX.
