Hi !

What I have promised, my feedback:

1 / TIG's script - surely my fault (I am a rookie in ruby scripting), copied the RB in plugins folder with the right file name, but I have not found the 'command' in any menu. I have tried to write a menu definition according other RB scripts but I did not succeed, sorry.

2 / Didier's script - after his server came back to life I was shocked about how many scripts he has written. Congratulations! I have downloaded the right one and it does (in two steps) exactly what I need.

Thank you for your support!

My script does not have a menu entry.
It's usage as described is
TIG.faces2materiallayers
in the Ruby Console

Hi there,

is there a chance to make this script work for sketchup 2018?

The Tig version doesnt work

and the Didier makes the layers but doesnt put the faces in the layers.

kind regards

Edit the ancient RB file [in a plain-text editor, like Notepad++ or BBedit] and change the line:
def self
to read:
def self.faces2materiallayers
It should then work...
Then in the Ruby Console, to run it, you use:
TIG.faces2materiallayers

rbg

Thanks for the quick reply TIG

I have tried your adjustment and then i get this error code:

TIG.faces2materiallayers
Error: #<NameError: undefined local variable or method mat' for TIG:Module> C:/Users/richard/AppData/Roaming/SketchUp/SketchUp 2018/SketchUp/Plugins/TIG-faces2materiallayers.rb:11:in block in faces2materiallayers'

do you have any suggestions?

kind regards

This is a very very ancient RB...
Try this alternative...

### Copy/paste code into a file called
### 'TIG-faces2materiallayers.rb' in the Plugins folder
module TIG
def self.faces2materiallayers()
  model=Sketchup.active_model
  model.active_entities.grep(Sketchup;;Face).each{|face|
    next unless mat=face.material
    name=mat.display_name
    face.layer=model.layers.add(name)
  }
end
end
### Usage; TIG.faces2materiallayers

I think it'll work...
However, assigning layers to geometry, like faces and edges, is usually a very bad idea !!!!
They should almost always be given Layer0.

Dear TIG, after entering TIG.faces2materiallayers in ruby scriptbox I only get []. Any help?

TIG

For the avoidance of doubt, you must paste the whole of the code into the Ruby Console.
Then to run it use TIG.faces2materiallayers
For it to work there must be faces in the current active entities context, and they must have materials assigned to their fronts.
Faces within groups/components are NOT considered, unless you first edit the container to change the active entities context...

If those conditions are met, then any faces should be reassigned to a Layer named after their [front] material, which is made if it does not exist.

To reiterate my earlier comments, moving raw geometry to a layer other than Layer0 is generally not a good idea...
But if you want to do it then this way should work...

Hi TIG,

I'm dying to try the script. Question though: since Sketchup introduced tags as a replacement for layers, how would the script change? Looking forward to your reply, Gus

TIG

It doesn't change much at all - under the hood the API still calls them 'layers'.
Very similar to the way it still sees 'scenes' as 'pages' - changed because Layout arrived...
