But it seems no way to calculate the area...

def sum_area( material, entities, tr = Geom;;Transformation.new )
  area = 0.0
  for entity in entities
    if entity.is_a?( Sketchup;;Group )
      area += sum_area( material, entity.entities, tr * entity.transformation )
    elsif entity.is_a?( Sketchup;;ComponentInstance )
      area += sum_area( material, entity.definition.entities, tr * entity.transformation )
    elsif entity.is_a?( Sketchup;;Face ) && entity.material == material
      # (!) The area returned is the unscaled area of the definition.
      #     Use the combined transformation to calculate the correct area.
      #     (Sorry, I don't remember from the top of my head how one does that.)
      #
      # (!) Also not that this only takes into account materials on the front
      #     of faces. You must decide if you want to take into account the back
      #     size as well.
      area += entity.area
    end
  end
  area
end

Thank you for your help!

I want to deduct the overlapping area between componentinstance and componentinstance in model.
How do I change this code?
Thank you for your help!

mod = Sketchup.active_model # Open model
ent = mod.entities # All entities in model
sel = mod.selection # Current selection

as = mod.definitions["column"].instances
bs = mod.definitions["beam"].instances

hits = {} ### empty hash
as.each{|a|
es = a.parent.entities
hits[a]=[]
bs.each{|b|
next unless es = b.parent.entities ### same context
bb = a.bounds.intersect(b.bounds)
hits[a] << b if bb && bb.valid?
}
}
hits.each{|hit| puts "column #{hit[0]} intersects beam #{hit[1]}" }

TO TIG:
Thank you for your reply!
If I want to get the component's dynamic attributes(lenx, leny...) by multiple components collision detection?
and I will deduction of the overlapping area(multiple components) after...
(1)multiple components collision detection
(2)get the component's dynamic attributes(lenx, leny...)

Thank you for your help!

mod = Sketchup.active_model
ent = mod.entities

q = Sketchup.active_model.selection.add(
Sketchup.active_model.definitions["aaa"].instances )

a = Sketchup.active_model.selection.add(
Sketchup.active_model.definitions["bbb"].instances )

bb = Geom::BoundingBox.new.add(q.bounds.intersect(a.bounds))

if bb.valid?
puts "a"
else
puts "b"
end

It can't run...
How do I change the code?

Hello everyone

The following figure...
a and b intersect
b and c intersect
a and c not intersect

I get Leny, Lenz from dynamic attributes(inch)

How not to let the detected twice?(a&b and b&a)

Thank you for your help!

mod = Sketchup.active_model
ent = mod.entities
grp = ent.grep(Sketchup::ComponentInstance)
for i in 0...grp.length - 1
grp.each{ |g| next if g == grp[i] # skip comparing to self
bb = Geom::BoundingBox.new.add(g.bounds.intersect(grp[i].bounds))
if bb.valid?

#gg = g.get_attribute("dynamic_attributes","lenx","")
gg1 = g.get_attribute("dynamic_attributes","leny","")
gg2 = g.get_attribute("dynamic_attributes","lenz","")
#puts gg#.to_cm
puts gg1#.to_cm
puts gg2#.to_cm

#gg3 = grp[i].get_attribute("dynamic_attributes","lenx","")
gg4 = grp[i].get_attribute("dynamic_attributes","leny","")
gg5 = grp[i].get_attribute("dynamic_attributes","lenz","")
#puts gg3#.to_cm
puts gg4#.to_cm
puts gg5#.to_cm

q = gg1.to_i * gg2.to_i - gg4.to_i * gg5.to_i
puts q
#puts "#{g.name} and #{grp[i].name} intersect"
else
puts "#{g.name} and #{grp[i].name} do not intersect"
end
bb.clear

Hello everyone

How to detect collisions between ComponentInstance?

e.g:
if name = "column" all component collision name = "beam" all component
do something...
else
do something...
end

Hello everyone:

I want to know how to automatically calculate the component's area and volume in the dynamic attributes.

p.s:Non-use formula input.

Such as following example.

Thank you for your answer.

Hello everyone

mod = Sketchup.active_model
ent = mod.entities
grp = ent.grep(Sketchup::ComponentInstance)
for i in 0...grp.length - 1
grp.each{ |g| next if g == grp[i]
bb = Geom::BoundingBox.new.add(g.bounds.intersect(grp[i].bounds))

puts "#{g.name.to_s} and #{grp[i].name.to_s} intersect"
else
puts "#{g.name.to_s} and #{grp[i].name.to_s} do not intersect"
end
bb.clear
}
end

I want to know how to calculate the model of dynamic properties of all objects (such as "Lenx", "Leny" ,"Lenz"...etc) after the object intersected the other object.

The case description like this:

First, detect all objects intersect situations like the above code
Second, if name = "column" objects intersect name = "beam" objects(just a simple example)
then, "column" objects dynamic properties("Lenx") deduction "beam" objects dynamic properties("Leny")

Thank you for your advice and help

Hello everyone
I reference everyone's suggestion
The successful implementation of the following code:

mod = Sketchup.active_model
ent = mod.entities
grp = ent.grep(Sketchup::ComponentInstance)
for i in 0...grp.length - 1
grp.each{ |g| next if g == grp[i]
bb = Geom::BoundingBox.new.add(g.bounds.intersect(grp[i].bounds))
if bb.valid?
puts "#{g.name.to_s} and #{grp[i].name.to_s} intersect"
else
puts "#{g.name.to_s} and #{grp[i].name.to_s} do not intersect"
end
bb.clear
}
end

Thanks for everybody help and advice
The problem has been resolved

To TIG:
"valueq" is the argument I entered through Webdialog
by WebDialog (JavaScript pass value) to the ruby
I try to packaged this slab code with Class or Method(def...end)
and click the button to be able to run the code
but it seems problems in pass value and convert argument

Greg, I'm sorry because I tried it or not successful...
then, I think in this way, use "class...end"

the code like this:

class SphereTool
def slab(valueq)
...
end
end

sphere_cmd = UI::Command.new("Sphere") {
Sketchup.active_model.select_tool SphereTool.new
}

sphere_cmd.small_icon = "sphere_small.gif"
sphere_cmd.large_icon = "sphere_large.gif"
sphere_cmd.tooltip = "Create a sphere"

sphere_toolbar = UI::Toolbar.new "Sphere"
sphere_toolbar.add_item sphere_cmd
sphere_toolbar.show

but it shows...

"Nil result (no result returned or run failed)"
Error: #<NoMethodError: undefined method slab' for #<AS_RubyEditor::RubyEditor:0x00000007e1cad8>> (eval):76:in block (2 levels) in initialize'
SketchUp:1:in `call'

Sorry...Greg
I try to use instance variables like this:

def slab(valueq)
...
end
command = UI::Command.new("ss") { |@valueq| slab(@valueq) }

but ruby editor shows the situation like this":

cannot be an instance variable
command = UI::Command.new("ss") { |@valueq| slab(@valueq) }

and...if I change the code like this:

def slab(valueq)
...
end
command = UI::Command.new("ss") { |valueq| slab(valueq) }
command.small_icon = command.large_icon = path + "/slab.png"
command.tooltip = command.status_bar_text = "s"
menu.add_item command
toolbar.add_item command
toolbar.show

ruby editor shows the situation like this":
Error: #<TypeError: no implicit conversion of NameError into String>

It seems to be...undefined local variable or method ‘menu’ and ‘toolbar’ for command...

Hello everyone:
I want to know how to make toolbar in method(def..end) has parameters
e.g.

def slab(valueq)
....
....
....
path = File.dirname(FILE) + "/image/"
menu = UI.menu("Plugins").add_submenu("xx")
toolbar = UI::Toolbar.new("xx")
command = UI::Command.new("ss") {slab}
command.small_icon = command.large_icon = path + "/slab.png"
command.tooltip = command.status_bar_text = "s"
menu.add_item command
toolbar.add_item command
toolbar.show

Thank you for your answer!

Hello sdmitch:
First of all, thank you for teaching, I changed your code to meet my needs.
Please look at this picture, ruby console return
"one and two intersect
one and three do not intersect"
so I also want to know how to return
"two and three intersect"
Need to write a loop(for...end)?

Because I want to deduct the intersection surface of the overlapping area,
so I need to detect whether all elements of the model intersect.

Thank you for teaching again.

I want to detect whether all elements of the model intersect
Like this, but I have no solution, please give me advice, Thank you very much!

p = mod.entities.find_all {| ent | ent.is_a (Sketchup :: ComponentInstance)?}

bb = p.bounds.intersect (p.bounds)
if bb.valid?
if p.description == "one"
p.get_attribute ("dynamic_attributes", "name")
else
puts "B"
end
else
puts "no"
end
