You will no doubt have noticed that I originally raised this subject almost 9 months ago and apart from one response from an Autodesk representative suggesting that my root problem was the unsupported windows Vista platform I was using, I am very glad that you and other users have supported my stance that the 2013 version of the materials and asset editor element of Revit is a complete shambles. I am particularly pleased to see your comment about the lost manhours.
I for one will be extremely disappointed if the 2014 version, launching in the next week or so , does not address this issue. It would also be nice to see some Autodesk reaction to this issue.

I am with all of you on the lack of intuitiveness for the material editor in Revit 2013! It's almost counter productive - I simply want to change a material's physical properties and then retain those properties but change the colours, something that was relatively easy to do in 2012 now feels like walking a maze in 2013!
