Changing Layers within Blocks

[Burner]

I have a drawing with hundreds of blocks - glazing, doors, louvers, etc..  I would like to change the line colors within the blocks.  When I change the color using Layer Properties in model space, the color does not change withn the block itself.  

Rather than entering hundreds of blocks and changing the colors to ByLayer for each individual line, is there a workaround to do all the linetypes at the same time?  

I would like to avoid using the Explode tool.  Thanks!

Did you google ?

 

You need to edit the actual block definition basically a BEDIT on the block but via lisp.

 

Not something I have done Lee-mac may have something.
