Test Comp to see if it has Nested Components

[ktkoh]

This is the code I wrote to determine if a Component or Group contained any Nested Components. Is there an easier or more direct method of doing this??

mod = Sketchup.active_model # Open model
ent = mod.entities # All entities in model
sel = mod.selection # Current selection
obj = sel[0]
exp = "No"
  if (obj.is_a? Sketchup;;ComponentInstance) || (obj.is_a? Sketchup;;Group)
    ce = obj.definition.entities
    ce_a = ce.to_a # Make sel an array
    ce_a.each {|e|if e.is_a? Sketchup;;ComponentInstance then exp = "Yes" end
      }
  end # if obj
UI.messagebox("Explode Selection " + exp)

Try this

mod = Sketchup.active_model
sel = mod.selection
obj = sel[0]
cen = []
if obj.is_a?(Sketchup;;ComponentInstance)
	cen = obj.definition.entities
elsif objobj.is_a?(Sketchup;;Group) ### for < v2015
	cen = obj.entities
end
exp = "No"
exp = "Yes" if cen.grep(Sketchup;;ComponentInstance).length > 0
UI.messagebox("Explode Selection - " + exp)

Thanks that seems more straight forwad

A bit shorter ...more brute force.
The any? enumerable method returns boolean and stops on the first true result:

return unless obj.respond_to?(;manifold?)
ents = obj.entities rescue obj.definition.entities
any = ents.any? {|e| e.is_a?(Sketchup;;ComponentInstance) }
exp = any ? "Yes" ; "No"
