      Hi!

      FFD generally works fine with me but in certain cases I get strange results of transformation. Could someone, please, take a look at my model and tell me if there's something wrong with my geometry. It's just a mesh, nothing special.
      I moved a vertical row of 3 control points (selected yellow and yellow arrow on screenshot) but geometry went to the opposite side (white arrow).

        Same result that your but if draw vertical lines for "close" the sides
        that works as that must be πŸ˜„
        So maybe FFD don't love open surfaces ? πŸ˜„

          In fact your first object is not "clean" ! πŸ€“
          (lines coplanar, faces multiple etc...)
          Use CleanUp by Thomthom and all will be fine! πŸ˜„

              As you can see on my last image : after cleanUp seems all works fine on the good way! πŸ˜„
              (and without close sides)

                  Please give details of your SketchUp version, OS etc.

                  Also please explain the steps you are trying to use with this tool...
                  Double-check you are following the guidance given in the early posts...
                  Also run it with the Ruby Console open and report any error messages...

                  Remember that this tool is now five years without any support or updates...

                      As far as I know, if you install the current RBZ from the PluginStore it should work in v2018.
                      You must carefully follow the usage steps.
                      Your Extension Manager Loading Policy must be set to 'Unrestricted' to allow older [unsigned] extensions to load and run...

                          set your load policy to unrestricted, will load fine then

                          the extension will work the same whether it is signed or not, it is purely a mechanism to give the end-user some control over extension running on their system, in the end you (as in yourself) must make sure the extensions (and their sources) are trustworthy

                          Save the Earth, it's the only planet with chocolate.

                            Hi!

                            I have a problem with this plugin. I'm trying to match an FFD "box" to my group, which local axes are different from global axes of the model. I mean, they are rotated. I created an FFD group and it doesn't match my target group's axes. How can I match FFD group to local axes or my group? Instead, it matches the global axes. I could just reset rotation of my group, I know. But I don't want to do this.

                            Even if I change my model's global axes, FFD box orientation won't change. It will stick to initial orientation.

                                  This plugin can not work (error load) in sketchup 2019. How I could install this plugin correctly?

                                    This is an old script.
                                    Somethings have changed in v2019...
                                    Please try running it [following the earlier guidance] with the Ruby Console open and post any error messages you might get...
                                    If it's a simple issue perhaps we can fix it...

                                      This is the message I am seeing in conjunction with 2019

                                      Error: #<SyntaxError: C:/.../SketchUp/SketchUp 2019/SketchUp/Plugins/SketchyFFD.rb:32: Invalid return in class/module body
                                      return nil
                                      ^~~~~~>

                                      And a sincere thank you TIG, as this was not your plugin originally

                                        Try this fix...

                                        Find the file in your user's AppData tree C:/.../SketchUp/SketchUp 2019/SketchUp/Plugins
                                        named SketchyFFD.rb
                                        Edit it using Notepad[++] - a plain-text editor...
                                        Find line#32, and add a # to the start of the line, so that it reads:
                                        #return nil
                                        and is now ignored as it loads...
                                        Save the file, and restart SketchUp to see if that helps...

                                        The latest version of Ruby now shipped with v2019 is more unforgiving of simple syntax errors - previously this was just ignored !

                                          TIG - will this required syntax discipline actually reduce certain types of issues with plugins, or is it simply an added annoyance for extension developers?

                                            Thank you for the quick reply TIG.
                                            Your suggestion took care of the error message I was seeing. No error messages at load time now, but does not actually load. I saw your previous post:

                                            Please try running it [following the earlier guidance] with the Ruby Console open and post any error messages you might get...

                                            Wading through the 13 pages of posts associated with SketchyFFD to try and find the guidance. I will do my best to get you some more clues.

                                            May have to learn Ruby.
