Using transparency 'byblock' (a nice tool)

Hi ,

Here is a demonstation of a great code that will set transparency of blocks as 'byblock'
I use transparency many times to get a certain display in a 3D view or in a drawing.
If you set all objects 3D object byblock the xref as a whole can be made transparant. I think that is powerful.

I didn't programm it myself, just wanted to shared this great tool here for you guys.
If you have any good ideas of suggestions for imporvement , please do.

Hans
