      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.

        Edit the script with a plain-text editor [Notepad/Notepad++.exe] and add this code at the end

        unless file_loaded?(File.basename(__FILE__))
          UI.menu("Plugins").add_item("Change Arc Segments"){
            segments=inputbox(["Segments; "],[12],"Change Arc Segments")
            changearcsegments(segments[0])if segments
          }
        end
        file_loaded(File.basename(__FILE__))

            Hi!

            Is Anyone so kind to tell me how to use this plug-in.

            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.

              It doesn't even use ArcCurveTests.rb or mention it in its code - in fact in earlier posts [in this thread] you are recommended to remove that very file from your Plugins folder, because changes to the API have meant that it might clash and updates of this tool no longer need it anyway.
              So it is not 'required' by the recent versions of this script...
              Your error message leads me to think that you have an old version of the tool loading...
              Are you sure you have got the latest one in the Plugins folder? Windows Vista/Win7 can 'play tricks' if you don't have full access rights to the Plugins folder - it looks like you have added/updated a file/subfolder... but there's a 'Compatibility Files' button added to the folder's window-bar and they have actually gone into a side folder, IF you haven't got full security access rights to a folder [right-click context-menu Properties > Security]

              Here's the latest version http://forums.sketchucation.com/viewtopic.php?p=158903#p158903
              It has the Plugins menu item added to the code as discussed a few posts back...
              Download the latest file from this link.
              It should make a Plugins menu item which opens a dialog into which you type the number of arc segments required to process all selected arcs/circles...

                Hi!

                I downloaded the plugin and istalled it. I have a big drawing with many arcs and is nearly impossible to select them all. So i select the whole drawing as i imported it and then i use the plugin. But the plugin works only with some of the arcs and the others remain with the default number of segments.

                How can i use the plugin on all the arcs?

                Thank you in advance.

                  SketchUp's Arcs/Circles can have their 'segmentation' set as they are made OR later on by using 'Entity Info', OR bu using this tool.
                  BUT Arcs that have been scaled, exploded into edges OR are now incorporated into 3d geometry [extrusions etc] are never changeable.
                  So if you can't change your Arc's segmentation using 'Entity Info', then you can't change it with anything else either: its properties have been fixed by your earlier actions.

                    I can change the segmentation from entity info but the arcs are too many. So I tried to select the whole drawing and change the segmentation with the tool but only few of the arcs got the segments I wanted.

                      Wireframe mode will avoid picking faces, then select-by-fence, missing out anything that is obviously not an edge/curve...
                      Any errors in the Ruby Console ?

                        Thank you for your instant replies.

                        I don't have any faces in my model. I don't really understand what you mean with the fence selection. (This is my first model in SketchUp 😳 )

                        I don't get any errors at all. I just select all the lines and arcs (because i said in the first post that it is impossible to select every arc with clicks), then i use the plugin and i set the desired number of segments. Unfortunately not all the arcs get the number of segments I set in the plugin dialog box.

                            Thank you for your will to help me. As I understood the plugin can handle max 100 arcs at a time. I partially selected the whole model and everything was ok!

                                First of all: I am NOT a programmer, so there is ZERO error handling on this quick-and dirty script. I had tried TIG's solution, but did not work on my DWG because some of the arcs would "clip" others as they were rebuilt by the script.

                                So I wrote this small routine to:

                                • loop through imported AutoCAD entities.
                                • select curves and group them (individually)
                                • create a more refined clone of the curve (the number of segments is controlled by two parameters. See script)
                                • Delete the original curve.

                                Anyone is welcome to turn this snippet into something better and more reusable.

                                Best,
                                Marcos.

                                #set minimum length for each arc segment (in model units)
