      Hello,

      I do an automated ACAD-import and get some scenes converted from ACAD-views.

      Can I get a list with ruby of all existing scenes and iterate through the list
      and set each scene activ, zoom to the extents and then update the scene property.

      When I later click on the scene I get the correct view with all geometry in view.

      Regards

      Hans-Peter

        In earlier versions, Scenes where named Pages.

        To get list of scenes:
        Sketchup.ative_model.pages
        Returns a Sketchup::Pages collection object.
        https://developers.google.com/sketchup/docs/ourdoc/pages

        Iterate the collection which return Sketchup::Page objects.

          Hello,

          Thanks for the hints.

          
           model = Sketchup.active_model
           pages = model.pages
           pages.each {|page|
              pages.selected_page = page
              view = model.active_view
              new_view = view.zoom_extents
              status = page.update(33) 
              }
          
          

          Iterating through the pages seems to work.
          But they have now all the same view.
          How can I get the view of the selected page first and then do the zoom extent on that view?
          The page have different viewing angle after import. That should be preserved and only zoomed to extent.
          I do not see a page.view or something else.

          Regards

          Hans-Peter

            When the SketchUp engine does things to the UI on the C++ side, it often returns the Ruby call immediately before things are complete on the C++ side.

            In this case, the C++ side is not done animating the camera, when the next Ruby statement executes.

            So you can try using Kernel.sleep calls to insert pauses. (Adjust till things work right.)

            require('sketchup.rb')
            
            module HPW
            
              module SceneUtility
            
                @@pages_menu = nil
            
                class << self # proxy class
            
                  def scene_transitions?(model)
                    model.options['PageOptions']['ShowTransition']
                  end
                  
                  def set_scene_transitions(model,bool=true)
                    bool =( bool ? true ; false )
                    model.options['PageOptions']['ShowTransition']= bool
                  end
                  
                  def zoom_all_pages_to_extents()
                    model = Sketchup.active_model
                    pages = model.pages
                    trans = scene_transitions?(model)
                    set_scene_transitions(model,false) if trans
                    pages.each {|page|
                      pages.selected_page = page
                      Kernel.sleep(0.5)
                      model.active_view.zoom_extents
                      #status = page.update(33)
                      Sketchup.send_action('pageUpdate;')
                      Kernel.sleep(0.5)
                    }
                    set_scene_transitions(model,trans)
                  end
                
                end # proxy class
            
                ### RUN ONCE
                unless file_loaded?(File.basename(__FILE__))
                  #
                  @@pages_menu = UI.menu('Plugins').add_submenu('Pages')
                  @@pages_menu.add_item('Zoom All Pages To Extents') {
                    zoom_all_pages_to_extents()

              end # module SceneUtility
            
            end # module HPW
            

            If this does not work correctly.. then we'll have to implement a FrameChangeObserver.

              Doesn't sleep freeze up SketchUp itself?

                Yes it does.

                puts 'foo'; Kernel.sleep(5); puts 'bar';
                SketchUp doesn't respond at all until sleep is over.

                  It should not freeze the C++ side, which should continue animating or zooming the camera. It should only pause the Ruby interpreter.

                  And I likely showed more time than is needed in at least the first place in the example. The second place is dependent upon how many pages need updating thumbnails, etc.

                    Apples and Oranges.

                    puts is on the ruby side, ... of course sleep will pause between the two Ruby statements!

                      I should have been more specific - I cannot interact with SketchUp until sleep is over. The puts statements where just visual clues to know when it was over.

                          It's probably not perfect,.. and I did say this:

                          I'd likely use a UI.start_timer block along with a FrameChangeObserver if the sleep did actually interfer (perhaps SketchUp cannot call ViewObserver or PageObserver instances during sleep call ??)

                          So.. you could be correct Thomas. This the ol' workaround thingummy again. I wish the API would finish doing certain things, before returning a value from many API method calls (like setting pages, etc.)

                            I just whacked it out. 😳

                            I'll have to drink another cup of coffee, and put in a FrameChangeObserver

                              Rember, we cannot even use Ruby threads without blocking SketchUp. And wouldnt it be difficult for the Ruby engine to interact with the SketchUp engine and the entities if they ran in a separate thread/process?

                                OK, things seems not so easy.
                                The scene tab even does first appear after a autosart ruby has run, so no way to access the scenes via shortcut.

                                Other idea: Scenes can store the camera loctation. So can a ruby calculate a new camera location for each scene and write the property.
                                This would not update the screen or change the visible scene. But next time the scene-change is used it updates to the new location.
                                And the new camera locations are stored for each scenes in onSave.

                                What Propertys does ZoomExtents set? Is there a equivalent in ruby to calculate the values in the same way?

                                Regards

                                  This does what I want:

                                  
                                   model = Sketchup.active_model
                                   pages = model.pages
                                   pages.each {|page|
                                      pages.selected_page = page
                                      UI.messagebox("Scene; "+page.name)
                                      view = model.active_view
                                      new_view = view.zoom_extents
                                      status = page.update(33) 
                                      }
                                  
                                  

                                  But I have to press OK on the messagebox when scene-update has finished.

                                  Edit: Kernel.sleep does not work for that.

                                    Yes.. I guess we decided it would not, because the C++ engine cannot call observers, as the scene changes, etc.
