      I ADD THESE TO IT

      #def changearcsegments(segments)
      def changearcsegments
      model=Sketchup.active_model
      name="Change Arc Segments"

      ##================
      $ff_edges = 1 if not $ff_edges
      prompts = ["Change Arc Segments: "]
      value = [$ff_edges]
      result = inputbox prompts, value, "Change Arc Segments"
      return if not result
      $ff_edges = result[0]

      segments=$ff_edges

      ##================
      if Sketchup.version.split('.')[0].to_i >= 7

        That's fine - it's code that's to be used freely - please just credit me where credit is due and don't sell it. πŸ˜„

        Incidentally, I'd use @ff_edges [which sets it for that session for that script], rather than $ff_edges [which sets it globally for all loaded scripts that session and could clash if someone else has used it ! ]

        Why not also add some more code to make it a Plugins-Menu item or better a right-click Context-Menu item that gets shown only if the current selection contains an ArcCurve - a bit like the arc_center_point ruby?

        I was just demonstrating a possible use for the new method - you can puzzle over it and add any fripperies you like... πŸ€“

        Post your version when you're done - I suggest you call it something a little different to avoid script clashes...

          @ TIG: Cool Now with the Console I will be try this tricky code! β˜€
          Or maybe I am optimistic and some more code must be written ? The console use + code above are sufficient?
          The plug is "stand alone"?

          Edit: I Try the Console: works fine 😎
          And works also for the circles! 😲
          Bravo! πŸ‘

            The script I add just copy from the projectnormalface.rb.
            I try the @ff_edges it work well πŸ˜›
            Incidentally, i call scripts through the usertoolbar written by Jim ,so the ruby files i use no menu or button script (i delete them 😲 )

              For the volumes 3D from Autocad does it possible to make the same thing?

              Something like this in the Widows box option of SU importation : give minimum angle between facets
              (so numbers of segments of arcs will be limited by this value)
              But I don't know how is managed entities 😳
              I suppose 2 circles connected but... πŸ˜’

              here a cylinder from autocad


              cylinder.zip

                Unfortunately SUp doesn't allow [easy] editing of many of the properties of arcs or circles it they form parts of complex 3D shapes... Changing an arc or circle could change so many other things that are connected to it that it would quickly become unmanageable ! So, you cannot change the number of segments in an arc or circle using Entity Info IF it has connected faces that aren't coplanar with the arc/circle itself... My new 'method' has the same limitations...

                Sorry...

                    All this don't arrive if you use Moi πŸ˜‰
                    Here a simple cylinder with a hight number of segments πŸ˜„
                    (limit of the 24 segments default is overpassed πŸ˜‰
                    And you can control the aspect of polygons before exportation!
                    Exportation is in SKP format of course! β˜€

                      That is one of the key differences of solid modeler vs. face modeler.

                        Here is an updated version http://forums.sketchucation.com/viewtopic.php?p=158903#p158903
                        e.g. arcCurve.set_segments=6

                        You will need both of the rubies that are attached there...

                        The new file, ArcCurveTests.rb, includes three new methods is_loop?, .is_circle? and .is_polygon? - these methods are not accessible through Ruby otherwise...

                        They are used to determine the original ArcCurve's underlying 'type' [Arc/Circle/Polygon] and then use that to remake the geometry with the new segment/sides count as the right 'type' [previously any Circles/Polygons that were changed by this method became 'Arcs' !]...

                        EDIT: ArcCurveTests.rb updated... 20091002

                          Some of these methods can be simplified with the aid of Curve.is_polygon? added in Google SketchUp 7.1 - Maintenance 1.

                          Here's a set I made for my TT_Lib:

                          
                          	def self.is_curve?(entity)
                          		return false unless entity.is_a?(Sketchup;;Edge) && entity.curve
                          		return false if entity.curve.respond_to?(;is_polygon? ) && entity.curve.is_polygon?
                          		return true
                          	end
                          	
                          	def self.is_arc?(entity)
                          		return self.is_curve?(entity) && entity.curve.is_a?(Sketchup;;ArcCurve)
                          	end
                          	
                          	def self.is_circle?(ent)
                          		# (i) A bug in SU makes extruded circles into Arcs with .end_angle of 720 degrees when reopening the file.
                          		# Instead of checking for 360 degrees exactly, we check for anything larger as well. A 2D arc
                          		# can't have more than 360 degrees.
                          		#
                          		# This doesn't work. Maybe due to rounding errors?
                          		# return (arc_curve.end_angle - arc_curve.start_angle >= 360.degrees) ? true ; false
                          		return false unless self.is_arc?(ent)
                          		return ((ent.curve.end_angle - ent.curve.start_angle).radians >= 360) ? true ; false
                          	end
                          	
                          	def self.is_polygon?(ent)
                          		return ent.is_a?(Sketchup;;Edge) && ent.curve && ent.curve.respond_to?(;is_polygon? ) && ent.curve.is_polygon?
                          	end
                          	
                          	def self.is_ngon?(ent)
                          		return false unless self.is_polygon?(ent) && ent.curve.is_a?(Sketchup;;ArcCurve)
                          		return ((ent.curve.end_angle - ent.curve.start_angle).radians >= 360) ? true ; false
                          	end
                          
                          

                          SU versions prior to this .is_polygon? will not be able to tell a Circle or Polygon apart, but no error is thrown.

                                I've tried making a script that automatically creates an 8-sided circle in a group at sketchup start, to see if all circles created by a user would then be 8-sided as well. They aren't - scripting an 8-sided circle still leaves the default sides at 24. 😞

                                I tried changing the sides of a circle with this script as well - Sketchup still leaves the default at 24.

                                How can I change the default sides of a circle? ❓

                                    At least this script here just saved me time reducing polys from extruded circles.. thanks!

                                      TIG it's nice of you to share this with us. I think this ruby is very useful but it's convenient to use because everytime I have to type "changearcsegments NNN" in the ruby console...Why not make it possible to be added in the plugin menu and works with a popup window to type in the segment number.

                                            I get an error that says
                                            Error Loading File ArcCurve-set_segments=.rb
                                            no such file to load -- ArcCurveTests.rb

                                            any help?

                                            thx!
                                            p.s.
                                            I downloaded the script from the first post.
