So I posted a wish : http://forums.augi.com/showthread.ph...ch-in-an-Array where the administrators have decided this is resolved. I feel this has been incorrectly resolved. The reason is though The dynamic block has been resolved via a work around. The problem is that I should not have had to use a work around, which in this case was a flipped version of a given visibility state so I now effectively have two visibility states so that my DB works. without these two visibility states if I was only using one visibility state, parts would start glitching out of a defined area. This is better explained on the following thread in the Autodesk AutoCAD DB help forums: https://forums.autodesk.com/t5/dynam...p/td-p/8157826. I only ask the reason why this has been marked as already in the software where in my opinion this is actually a bug in the software that requires rectification.
