Global Block Hatch Edit

[martymoose]

Hello,

I need to globally edit hatch patterns on Layer 0 within blocks on a specific layer without exploding or bursting. Can this be done?

 

BEDIT will allow me to make my changes, but I'm looking to isolate these changes to blocks only on layer M-HVAC-EXST-DUCT.

 

This is a snipit of what I have so far:

 

 
(if (setq ss1 (ssget "_X" '((0 . "SOLID") (8 . "M-HVAC-EXST-DUCT"))))
(command "_chprop" ss1 "" "Color" 9 "") "regenall")

(if (setq ss2 (ssget "_X" '((0 . "HATCH") (2 . "SOLID") (8 . "M-HVAC-EXST-DUCT"))))
(command "_chprop" ss2 "" "Color" 9 "") "regenall")

 

This will effect all hatches on Layer M-HVAC-EXST-DUCT, but I need it to effect hatches on Layer 0 that are within blocks on that layer.

 

I may be way off base in my approach.

Any suggestions...
