I'll look at it when I get to my computer, but my solution was to just draw the various cmu sizes and use visibility parameters to hide the ones I don't want. Not as fancy, but gets the job done without much fuss.

You've got a lot going on there.

I was able to get the hatch change to work on the bottom two blocks and the top most block of the array. But all of the arrayed blocks between defaulted to the 4" block width. Were you able to get that far? If so, I'd suggest trying to reassign the hatch to the dynamic width and see if that works. I haven't bothered to install my full AutoCAD version yet (still running LT), so I can't do too much with the dynamic features. If I get some time later today I'll install it and take another stab at it.

PhamENG, thats what I am finding too. I will try updating the hatch to the dynamic width.

For whatever reason, after changing the hatch, I had to go back and change the height and bring back down. that updated the hatch
