I think, in this case, the last TIG.intersect?(ens[i], ens[j]) is with i=length-2 and j=length-1
Otherwise j = i+1 will become ens.length : for 5 elements (0 to 4) in ens, j will be 5.

i tried to run this code in sketchup 15 64 bits, thinking it could run faster than is sketchup 8

All the contrary

it is much slower in sketchup 15 64 bits... (about 10 times...)

i am very disapointed

am i the only one to experience that?

This is my version of the srcipt for now that seems to work for all non nested component instances

module Bob

# Huge parts of this code were written by TIG this is a sligthly modified version

	def self.intersectBob?(e1=nil, e2=nil)
	
		mod = Sketchup.active_model # Open model
		ent = mod.entities # All entities in model
		instance1 = e1 #sel[0]
		instance2 = e2 #sel[1]
		ci_def = instance1.definition 
		tr1 = instance1.transformation
		test1 = Sketchup.active_model.entities.add_instance ci_def, tr1
		ci_def2 = instance2.definition 
		tr2 = instance2.transformation
		test2 = Sketchup.active_model.entities.add_instance ci_def2, tr2
		result = test1.intersect(test2) 
		cnt = result.entities.count 
		if  cnt > 0
			int=true
			result.definition.entities.each {|ent|
			if ent.is_a? Sketchup;;Face
				ent.material = 'red' #Sketchup;;Color.new(255, 0, 0)
			end}
		else
		int=false
		end
		
	return int
	end 
	
	#def self.del()	#does not work like this typing Bob.del into the ruby console, meaning result has to be changed from local to global variable but I don't know how yet
	#result.erase!	
	#end	

	def self.intersectALL()
		model=Sketchup.active_model
		ss=model.selection
		ents=model.active_entities
		ss.clear
		gps=ents.grep(Sketchup;;Group)
		ins=ents.grep(Sketchup;;ComponentInstance)
		ens=gps+ins
		ens.uniq!
		ens.compact!
		(ens.length).times{|i|
			(ens.length).times{|j|
				next if j<=i
				if self.intersectBob?(ens[i], ens[j])
					ss.add(ens[i])
					ss.add(ens[j])
				end
			}
		}
		puts "Any intersecting component-instances are highlighted..."
	end
end

In this script I still need to fix the deleting function which later will have to be added to an observer class so as soon as another is clicked (or a button is pressed) the resulting intersection is deleted.

The more important function that still has to be added is that it does the check for all the nested components (and possibly groups).

I only have the 32 bits version so can't say
