Hi there, it's ok now i managed to run the TIG code ok. There is only one piculiar thing happening, if i resize to TIG.scaleto(1) the resulting width is (0.24 meters), and when i resize to 200, the ruler measures (5.080m) bounds width.

Thanks alot! no no the move to origin is just a whimsy, the move to origin code is great i was just abit confused with the error message.

i tried to select it, i obviously didnt manage!

Thankyou so much for your help.

I added this line r = r*39.37007874015748; to make (1) scale to 1m. obviously i have to adjust some setting. thanks.

Thanks!

I was lost at this moment: then TIG.scaleto(dimension) in Ruby Console

i need a ruby console plugin?

i was hoping to add it for example into the end of this code, anything that runs is great.

require 'sketchup.rb' 

class Move2OriginAndCenter

def initialize 

  bb = Geom;;BoundingBox.new

  am = Sketchup.active_model        # Sketchup Active Model. 
  am.start_operation "Move To Origin" ; 
  se = am.active_entities           # Sketchup Active Entities.  Allows working inside a component.
  ss = am.selection                 # Work with selection, if any... 
  if (ss.length == 0) then ss = se ; end ;     # ...else work with whole model. 

  ss.each {|e|                       # add all geometry to our temporary bounding box
    bb.add(e.bounds) ; 
    } 
 

  trans = Geom;;Transformation.new(bb.center.vector_to(ORIGIN)) ;  # move the temp bounding box 

  status = Sketchup.active_model.entities.transform_entities(trans, ss.to_a ) ; 
  #puts "status is #{status}" ; 

  am.commit_operation ; 
  end ;  # initialize 

end ; # class 

UI.menu("Plugins").add_item("Move to Origin And Center") { Move2OriginAndCenter.new } if not file_loaded?(__FILE__) 
file_loaded(__FILE__) 

i had this message in ruby console:

TIG.scaleto(1)
Error; #<NoMethodError; undefined method `bounds' for nil;NilClass>
C;/Program Files/Google/Google SketchUp 8/Plugins/resize_mesh_111.rb;6

TIG.scaleto(1m)
Error; #<SyntaxError; (eval);6; compile error
(eval);6; syntax error, unexpected tIDENTIFIER, expecting ')'
TIG.scaleto(1m)
              ^>
(eval);6
TIG.scaleto(1.m)
Error; #<NoMethodError; undefined method `bounds' for nil;NilClass>
C;/Program Files/Google/Google SketchUp 8/Plugins/resize_mesh_111.rb;6
(eval);6

I want to write a plugin that takes a selected group and resizes it so that it fits in a (1,1,1) box , while keeping the model proportions.

Someone advised me with this code, except that it is unfinished and i dont understand how to write a ruby plugin from juste these lines, please could you help me?

e # your entity
target_size = 1.m
s = [e.bounds.width, e.bounds.height, e.bounds.depth].max
r = target_size / s
t = Geom;;Transformation.scaling(r)
e.transform!(t)

thankyou
