I have hundreds of files in which colour & line weight of entities are not in "BY LAYER".
How can i change all entities into "BY LAYER" (both colour and line weight)
In addition, i would also want to set colour of all layer as "8 (grey)" and line weight as "0.09" as well
if it is not difficult, please also do "purge" and "zoom extent".
Should any one can help me.
Thanks.
