Select all geometry

N Lindenthal

This is my ruby script »Aar_Select_comp_by_name.rb« in the Plugins folder:

def select_comp_by_name(comp_name)
model = Sketchup.active_model
sel = model.selection
sel.clear
compdef = model.definitions[comp_name]
if compdef #There is a component
sel.clear
sel.add compdef.instances
else
UI.beep
end
end
#def select_comp_by_name(comp_name)
#@sel = Sketchup.active_model.selection
#@sel.clear
#@sel.add Sketchup.active_model.definitions[comp_name].instances
#@sel
#end

If I repeat loading by ruby console:

load "Aar_Select_comp_by_name.rb"

then come the following notes

… but also »true«.

Now with ruby script line

Sketchup.active_model.definitions["Stein"]

I get
@unknownuser said:

nil

and with

> select_comp_by_name("Stein")

@unknownuser said:

Error: #<NoMethodError: undefined method ` ' for main:Object>
/Library/Application Support/Google SketchUp 6/SketchUp/Plugins/Aar_Select_comp_by_name.rb:2
(eval):197

… nothing is selected.

Hi !
Your script works fine here... Be careful with case of the definition name... I found no error in your script...
Perhaps some parenthesis

sel.add(compdef.instances)

and unnecessary duplication

sel.clear

Erase the second duplication.

@Matt666
Thanks for your corrections.
When your script runs fine, in the end you have the component "Stein" selected?

I tried with a component called "essai" created before. I had five components, and they had been all selected in the end.

Can you upload an example I can test, please ?

N Lindenthal

Matt, here is my model to select a component by name "Stein"

FahrstuhlF.skp.zip to selcect component by name

Matt666

Ok I understand your problem...
I have made a component called "test". Entity info window looks like this :
With your component, entity info window looks like this :
The script search for component with definition as ["Stein"]. But your component definition is called "<gruppe#4> in the Skecthup database. His NAME is "Stein".

3 methods :

Create a component directly, without create a group first. Your first ruby script will work.
Change your ruby script, and don't change your method.
Try this in the ruby API :

Sketchup.active_model.definitions.each{|d|return d if d.name == "Stein"}

This code returns the name of the component definition which called "stein"
And the ruby script :

def select_comp_by_name(comp_name)
   model = Sketchup.active_model
   sel = model.selection
   sel.clear
   compdef = Sketchup.active_model.definitions.each{|d|return d if d.name == "Stein"}
   if compdef  #There is a component
      sel.clear
      sel.add(compdef.instances)
   else
      UI.beep
   end
end

Add a line in ruby which control name of all component definitions if C definitions not found...
Like this :

def select_comp_by_name(comp_name)
	model = Sketchup.active_model
	sel = model.selection
	sel.clear
	compdef = Sketchup.active_model.definitions[comp_name]
	Sketchup.active_model.definitions.each{|d|return d if d.name == "Stein"} if not compdef
	if compdef
      sel.clear
      sel.add(compdef.instances)
   else
      UI.beep
   end
end

Not tested, but it sould work !
Tell me if you want more explanations

@Matt666
I did understand you. First changes did not delete my error. Hm? What could it be?

Matt666

Oops !! A little bug !!

In fact, name is linked to the component, not to the component definition.
So you have to search around all the component in the drawing to select component with specific name, if no component definition have this specific name....

Like this :

def select_comp_by_name(comp_name)
	model = Sketchup.active_model
	sel = model.selection
	sel.clear
	if compdef = Sketchup.active_model.definitions[comp_name]
		sel.add(compdef.instances)
	else
		Sketchup.active_model.active_entities.each do |d|
			if d.typename == "ComponentInstance"
				sel.add d if d.name==comp_name
			end
		end
		if sel.count == 0
			UI.beep
		else
			UI.messagebox(sel.count.to_s + " entities found.")
		end
	end
end

Qui!
Now your script runs, Matt666. My component is selected by name/definition. As it is selected, I can »Get Position - X« (Proper_animation.rb from RichW).

Matt666, you have my elevator model with arrow buttons. With Links.rb the arrow up buttons will select the elevator and »Get Position - 2«. The arrow down buttons will select the component elevator and then »Get Position - 1«.

But my question is, whether I can start a ruby.rb script by clicking a button.
