      I've tried doing everything possible and can't seem to get any output in the ruby console from either plugin. Can you tell me exactly how to reproduce it?
      For example...

      @unknownuser said:

      Error: #<NoMethodError: undefined method curve' for #<Sketchup::Group:0xa9d06fc>> C:/Program Files/Google/Google SketchUp 8/Plugins/recurve.rb:17:in can_select_curve?'
      C:/Program Files/Google/Google SketchUp 8/Plugins/recurve.rb:32:in `can_select_curve_selection?'
      C:/Program Files/Google/Google SketchUp 8/Plugins/recurve.rb:352

      When right clicking a tagged 'surfacegen-group'.
      Explode the special surgfacegen-group and right-click gives

      Error: #<NoMethodError: undefined method curve' for #<Sketchup::ComponentInstance:0xb440344>> C:/Program Files/Google/Google SketchUp 8/Plugins/recurve.rb:17:in can_select_curve?'
      C:/Program Files/Google/Google SketchUp 8/Plugins/recurve.rb:32:in can_select_curve_selection?' C:/Program Files/Google/Google SketchUp 8/Plugins/recurve.rb:352 C:/Program Files/Google/Google SketchUp 8/Plugins/recurve.rb:17:in call'
      C:/Program Files/Google/Google SketchUp 8/Plugins/recurve.rb:17

      Erase that 'bounds' Instance then Select the surface...

      C:/Program Files/Google/Google SketchUp 8/Plugins/recurve.rb:17

      These all relate to 'recurve' reaction to 'surfacegen' entities ?
      I did have a surgacegen error but I can't get it to reproduce now 😕

        Nice! Can't wait some more complex math sculptures... and naturally even more functionality, like with K3DSurf.

        Little test...

            That's really nice! What's the equation you used?

            @TIG
            Make sure you have the latest version of Recurve. I fixed that bug with the last update which is why I couldn't reproduce the error. If you ever get the SurfaceGen error again let me know.

            @Pilou
            Just re-select the group with the select tool. It seems that the SelectionObserver doesn't fire when the selection is changed in code.

              You are right, in that when I get v1.4 of 'recurve' I no longer get these errors with 'surfacegen'. However, I had v1.3 [with SUpv8] and there were no major changes except for making it SUpv6 friendly ?
              Anyway... no more error messages... I'll try to break it 😉

                  this is great,

                  some odd behavior on the Mac... when run from plugins (like you should) I get this

                  Error; #<ArgumentError; Cannot convert argument to Sketchup;;Point3d>
                  /Library/Application Support/Google SketchUp 8/SketchUp/Plugins/SURFACEGEN_Dir/surfacegen_tool.rb;266;in `add'
                  /Library/Application Support/Google SketchUp 8/SketchUp/Plugins/SURFACEGEN_Dir/surfacegen_tool.rb;266;in `getExtents'
                  

                  if I put the surfacegen.rb into the folder do a restart and then load from Ruby Code Editor, I get this

                  (eval);428; warning; don't put space before argument parentheses
                  "Run aborted (error has occurred)"
                  (eval);428; warning; don't put space before argument parentheses
                  (eval);10; warning; already initialized constant SURFACEGEN_DIR
                  (eval);11; warning; already initialized constant GRAPH_SIZE
                  (eval);12; warning; already initialized constant WINDOW_HEIGHT
                  (eval);13; warning; already initialized constant ATTR_DICTIONARY
                  "Run aborted (error has occurred)"
                  

                  but if I restart again and use as_pluginloader.rb to load it I get

                  
                  /Library/Application Support/Google SketchUp 8/SketchUp/plugins/SURFACEGEN_Dir/surfacegen.rb;428; warning; don't put space before argument parentheses
                  

                  it works, but has no tool button image...
                  the dialog keeps disappearing behind SU, but that needs show_modal on Macs
                  this is a 'normal' load i.e. image-no dialog

                  learn from the mistakes of others, you may not live long enough to make them all yourself...

                    That's really nice! What's the equation you used?

                    F(x,y,z) = 2-(cos(x+(1+sqrt(5))/2*y)+cos(x-(1+sqrt(5))/2*y)+cos(y+(1+sqrt(5))/2*z)+cos(y-(1+sqrt(5))/2*z)+cos(z-(1+sqrt(5))/2*x)+cos(z+(1+sqrt(5))/2*x))*16/(x*x+y*y+z*z)
                    [x]; -5, 5
                    [y]; -5, 5
                    [z]; -5, 5
                    

                    There is plenty more at the k3dsurf forum.

                      Perhaps you could add some more functionality; like functions min, max and abs. Also allow use of arithmetic operations and pi in axes, like -2*pi.

                          The SelectionObserver has always been very buggy: http://www.thomthom.net/software/sketchup/observers/

                            Just uploaded a fairly major update to the first post!

                            @driven
                            This should fix the issues with macs. It now uses cross-platform methods to locate and load resource, and uses show_modal rather than show on macs with the WebDialog.

                            @notareal
                            The axes now let you use an expression such as 2*pi

                            @d12dozr
                            Helpful error message are now shown when an expression is invalid.

                              One minor error in getExtents in surfacegen_tool.rb
                              Line #270 result.add @p0 if @state >= 0
                              can raise an error so adjusting it to
                              return if !@p0 or @p0.class!=Geom::Point3d; result.add @p0 if @state >= 0 might help - you could also add similar validity checks on the other points that are added to the extents ?

                                I've updated the first post. It shouldn't show those errors anymore.

                                    Just updated again fixing a small bug with the expression parser.

                                    Check out this graph:

                                    http://i59.photobucket.com/albums/g314/diggsey/th_face.jpg

                                    Equation = min(((max(abs(y)-(2sqrt(z+4)) ,(x+0.5abs((abs(y)+4)/3.5)/(1+(((abs(y)+4)/3.5)^2-2)^2)/2 2/(1+(z-2)^2)+abs(y/1.5)^3.5/7 ) )max( max( abs(x+0.15+(y/0.7)^2)+(z-1.3)/1.4,max(z-2.3, max( abs(x+0)/2.4 -1+2abs(1.5y)+(z+0.1)/2 , -z ))) ,x-0.8+z/2)-0.1 )*(abs(x+y^2/3)-0.2+abs(abs(z+1.8)-(0.5-(y/2)^2) )^1.2 )-0.1 ),( (x+1.2+abs(y)/10)^2+(abs(y)-1.1)^2/2.5+(z-2.3)^2/1.8-0.64))
                                    x: -3 to 1
                                    y: -4 to 4
                                    z: -4 to 5.4

                                    @TIG
                                    Yes you can use any built in ruby function;)

                                    @jim
                                    I can't make the window resizable because it is shown and hidden by resizing it to a fixed value and zero respectively, and there is no API function to get the size of the window to save it. However, you can easily change the height of the window. Open surfacegen.rb in notepad and change the line "WINDOW_HEIGHT = 320" to about "WINDOW_HEIGHT = 350". You can try different values until you get what you want.

                                      yes,

                                      working on the mac...

                                      I don't know if I downloaded before or after your latest tweak,
                                      is there a version number somewhere on the files?

                                      another thing, is it possible to have a 'use last' settings option?

                                      playing around with the box size on the head requires [re]inputting the data each time
                                      cheers

                                        If you need to use the same settings as last time just copy and paste the graph, and then change the settings you need to. All the settings are stored as attributes of the graph so will be copied with it. If you need to change the size you can use the scale tool just as easily as creating a new graph.

                                            BTW.. the varying size of content seen by jim is most likely due to your using [ font-size: 8pt; ] as although 1px=0.75pt different browsers treat pt oddly,

                                            with safari, in SU, on my mac 8pt is reading as 8px and everything fits if a bit small.

                                            learn from the mistakes of others, you may not live long enough to make them all yourself...
