Change lineweight to ByLayer in multiple blocks at once

[ilporte]

I'm working in a document that I didn't make and each door is its own block (for scale, this is a building with 8 floors - it's a lot of doors). I need to go through and change the lineweight and color on every door to "ByLayer" so that I can control them from the layer list. Is there a way to do this without opening every single block individually or going through and replacing all of my doors?

Thanks for any thoughts and solutions!

Not sure how the program is going to guess which blocks in your files are just doors, and not windows or anything else.

Would you want this ability to work on all blocks in your file?

It would be helpful to know what program you are using..

Search and read about SetByLayer / SetByLayerMode

I'm using AutoCAD Mac 2018

Yes! I'd be happy to have this affect either all of the blocks in my document or any blocks that I select.

And if you need this file only as XRef, search and read about Xrefoverride.

It's not an XRef - I need the drawing organized differently than whomever created it.

For mac, ok - not my Version but i like to help.

SetByLayer is not available in the mac versions, but you can run a 3.part extension or you can reach the goal by clever worksteps an laymrg.

Something like this

(setq  doc (vla-get-activedocument (vlax-get-acad-object))) ; open database
(setq allblocks (vla-get-blocks doc))

; converts  blocks to bylayer proerties 
  (vlax-for block allblocks 
   (if   (not (wcmatch (strcase (vla-get-name block) t) "*_space*")) 
   (vlax-for   ent block 
   (vla-put-color ent 0) 
   (vla-put-linetype ent "Bylayer") 
   (vla-put-lineweight ent aclnwtbyblock) 
   ) ;_ end of vlax-for 
      ) ;_ end of if 
    ) ;_ end of vlax-for 
  (vla-regen doc acactiveviewport)

Thank you all! I'm trying to get these to work and I got a setbylayer lisp working, but it doesn't go into the block. 

Alan - I haven't worked a ton with custom commands, but I don't recognize the structure of the code you posted. Where can I use that to help me?
