would help if we got the whole error - with the line number and traceback

The file "test.rb" is in plugins folder.
That´s the whole code of test.rb

  model = Sketchup.active_model
  layer = model.layers.add "ABS_Grundriss_Wand2"
  layer.color = [255,255,255]

The following error message appears if Sketchup start:
%(#FF0000)[Fehler beim Laden der Datei test.rb
undefined method `page_behavior=' for nil:NilClass]

That error appears in context with "layer-color=.rb" which is in
plugins folder too. If I remove "layer-color=.rb" from plugins folder
there is the following error message:
%(#FF0000)[Fehler beim Laden der Datei test.rb
undefined method `color=' for #Sketchup::Layer:0x6dfe1ec]

That error I understand.

Have you restarted SUp after installing the new code script ?

Yes

@tig said:

There is no built-in API layer.color=
BUT see here for my stop-gap new method... http://forums.sketchucation.com/viewtopic.php?p=177016#p177016
with that loaded your example layer.color= [255,255,255] should work...

I tried that. I copied "layer-color=.rb" to plugins folder.
And than there was the error when I start my code.
What is the mistake I made?

I tried it with "layer-color=.rb"

  layer = model.layers.add "my_layer"
  layer.color = [255,255,255]

But there is the following error:
"undefined method `page_behavior=' for nil:NilClass"

Do you have an idea why the error occurs?

Is it possible to set the layer color by ruby-code?

Make an array of the selected edges [or of the edges within selected groups etc].
Iterate through those edges and test it they have >1 face.
Soft/Smooth them...

Save code as makesoftsmooth.rb or use the def as part of a broader tool.
Execute it as makesoftsmooth()
...

Thank you!
That works well, if the edges not in a group.
But on edges in a group it doesn´t work.
What should I do so that it acts on the edges in a group?

@jim said:

... you will need to write your own soften method.

How does it work? Do you have an idea?

I want to use the menu command "Soften Edges" from the "Window"-menu by ruby.
Can someone tell me how does it work?

Hi,

I would like to insert "Group1" into "Group2" by ruby-code.
What should I do to make this work?

@thomthom said:

my_group = all_groups.select{|g| g.name == "G1"}.first

Thanks - that´s exactly what I need!!!

@tig said:

...Assuming you corrected the group >> my_group it should work IF the names match...

It does not work.

all_groups = Sketchup.active_model.entities.find_all{|e| e.class == Sketchup;;Group}
my_group = all_groups.select{|g| g.name == "G1"}
my_entities = my_group.entities

The result is:

all_groups = Sketchup.active_model.entities.find_all{|e| e.class == Sketchup::Group}
finds several groups
=> [#Sketchup::Group:0x80db350, #Sketchup::Group:0x80db320, #Sketchup::Group:0x80db2f0, #Sketchup::Group:0x80e6768]

my_group = all_groups.select{|g| g.name == "G1"}
picks one of the groups
=> [#Sketchup::Group:0x80e6768]

my_entities = my_group.entities
gives the following error
NoMethodError: (eval):1:in get_binding': undefined method entities' for [#Sketchup::Group:0x80e6768:Array]

I don`t understand that!!!

Is there anybody who can explain it to me?

@tig said:

You first get a reference to the required group, then one to its entities, and then do stuff in that entities collection...
To see if each step is working add puts my_group etc after it's defined it should then print up the group-id in the ruby console or 'nil'!
It should be my_group in your code if you want to work inside that group.
Do you have a group with that specific name ?
Obviously the .add_face(...) needs expanding so the ... is a list of at least three coplanar points!!
It WILL work...
Why not test it using my method that adds a new group to model.active_entities with
my_group=model.active_entities.add_group()
NOW you are sure to have my_group... now add the face to my_group.entities

Hello TIG,

I need access to an existing group to add a face. I would like to make a cutout in a wall (existing group) to insert a door or window.

@jim said:

You work directly with the Group's entities, just like you would the model's entities. Having an editing context is a useful concept for people when modeling, but is not necessary when editing geometry using the Ruby API.

This sample shows how you might get to a Group's entities.

> all_groups = Sketchup.active_model.entities.find_all{|e| e.class == Sketchup;;Group}
> my_group = all_groups.select{|g| g.name == "My Group"}
> my_entities = group.entities
> my_entities.add_face(...)
> 

my_entities = group.entities don´t works.
I think it must be:
my_entities = my_group.entities
but that don´t works too.

Can someone help me?

Thanks
Andreas

Hi!

Is it possible to edit a group by ruby-code instead of a right mouse click in contextmenu.

Thanks...

Andreas

Hi,
I generate plugin by various parts and then summarize them into one group.
This works very well:

mogroup = entities.add_group elements

Now I want to pick this group also right at the end of the plugin via Ruby code. So I not have to select the just created group by using the mouse.

Can anyone help me?

Thank you!

Greeting
Andreas
