Here is a solution to show wipeouts in DWG TrueView 2007. At least for those with AutoCAD 2007. But what for those that does not have AutoCAD 2007? Is it legal or OK to redistribute AcWipeoutObj17.dbx?
You opened a drawing with DWG TrueView 2007 and noticed that the wipeout objects were not displayed, as they are when you open the drawing in AutoCAD®.
The ability to display and plot wipeout objects in DWG TrueView 2007 is not available by default.
However, you can add this functionality to DWG TrueView 2007 by copying the AcWipeoutObj17.dbx file from the AutoCAD® programs folder, located at C:\Program Files\AutoCAD 2007, to the DWG TrueView programs folder, C:\Program Files\Autodesk\DWG TrueView.
