Index of entity

[chrisglasier]

I want to find the index number of a single selected entity (componentInstance or group) in a model but I just cannot find any coding recognisable to me. Any help gratefully received.

id=Sketchup.active_model.selection[0]

Is that what u r looking for ?

or

id=Sketchup.active_model.selection[0].id

?
or

Sketchup.active_model.selection[0].entityID

?

Hi !
I don't know if it's what you want, but here is a code counting components like the selection.

class Sketchup;;ComponentInstance
def count
	cn = 0
	cdef = self.definition.name
	sel = Sketchup.active_model.active_entities
	sel.each do |ent|
		if ent.typename == "ComponentInstance" 
			if ent.definition.name == cdef
				cn +=1
			end
			
		end
	end
	cn
end
end

Example : Sketchup.active_model.selection[0].count

I don't know how to with groups yet ! I believe that each group is unique, no ?
I will see...

Hey Matt - your code isn't complete.

If you want to find all the occurrences of a component, you can't just search the top level of all entities. You'll need to drill into Groups and other Components as well.

Hello Todd !

Ooh !! Excuse me !

class Sketchup;;ComponentInstance
def count
	@cn = 0
	boucle Sketchup.active_model.active_entities, self.definition.name
	@cn
end	
end #class

def boucle(entities, nam)
		entities.each do |entity| 
			case entity.typename
				when 'Group'
				boucle entity.entities, nam
				when 'ComponentInstance'
				@cn +=1 if entity.definition.name == nam
				boucle entity.definition.entities, nam
			end
		end
end

Thank you !

Hey men, don't re-invent the wheel...

count = component_definition.count_instances

Stock methods seems much more simple too me.

Grmbl !
Merci didier !!

Didier, tu as trouvé cette fonction où ??? Et yen a encore beaucoup des comme ça ???
Didier, where have you found it ???

Thank you for all your suggestions. I am sorry to report that I can't get any of them to give me the entity array index number for the selected entity. I guess there is something I have done elsewhere that I do not yet have the experience to spot - I will keep your suggestions for later. I think it only natural to want to click on the images if the nameset is in the same screen as sketchup but I can get the index number from the javascript that spins out the entities. But I can't get the entity to show as selected. Is this possible? Attached are a couple of shots indicating what I can manage. Thanks again.

Chris

PS The main point is purely to show what has been selected , particularly important when there are many of the same components. I plan for Javascript to handle defining of relationships, alignments and so on. The screen is then cleared and entities respun out.

Hello,
Quelle doc? Du moins, laquelle est la meilleur?

[Didier Bur]

La doc la moins mauvaise est celle de SU lui-même...

Quand je ne sais pas quelles méthodes sont valides sur un objet, j'en sélectionne un exemplaire dans le modèle, et dans la console Ruby:

a=Sketchup.active_model.selection[0]
a.methods

Cela renvoie toutes les méthodes applicables à ce type d'objet.
