      • Tig, although your solutions on material.name=, layer.delete, material.delete are good, it seems to me it would be much easier to just have them in the API.

      And it would be faster.

      • make the entity.id consistent throughout different SU sessions (it changes now from time to time)

      Ditto!

      • it would be great if you could just select an entity based on a parameter (eg. entity.id) without looping all the entities in the model

      Ditto. If you have a script that requires observers attached to some objects one want these to be reattached when the model is loaded. Currently one has to iterate the whole model to find the entities, and one has to attach an attribute to be able to find the correct one - which means string comparisons which are really slow.
      So a better way to directly reference entities across sessions would be a great addition.

      @pout said:

      • make a difference between the execution of scripts and the interface so it is possible to incorporate a 'stop script' button for example. Now the interface freezes as long as scripts are running. This makes users believe the execution of the script has halted and Sketchup has stopped working.

      while true puts 'Ditto!' end

        does anyone know if any of the remarks here will be taken into consideration in a new version?

          Sketchup::load

          The Sketchup::load method does NOT expose the wrap argument, so we can specify wrap=true for rbs scripts.

          For some unknown reason, the Google team defeated, or just didn't pass the 2nd argument (wrap) on to the aliased standard load, when they overrode it to handle rbs decrypting.

          Please fix this!_

          Taking this a step further.

          Since the rbs code blocks are eval'd, and Sketchup.load is an override (redefinition,) just pass the 2nd argument to Sketchup.load (if given,) on as the 2nd argument to the eval method.

          That way developers can instantiate a binding() to their custom namespace(s), and have the code evaluated within that scope.

          This can also give the GSUT the opportunity to protect some Google namespaces, within the argument validation block of the Sketchup.load method (ie: raise a custom "NotAllowedError" exception.)

            EDITED:Get||Set Layer Material & Color


            Added missing "wish" statement to set Layer color in the example I gave (the last statement.)

              Being able to set Layer colour.

              ..and also a "getter" method to read the color.

              Actually when you manually click the color button in the Layers dialog, the Edit Material dialog appears. If you choose 'Use texture image' and assign a texture file, the layer will be displayed with that texture over the layer color, when 'Color by Layer' is true, and rendering mode is 'Shaded with Textues'.

              Issues:
              (1) Technically, Layers have a material attribute that holds a Sketchup::Material object.
              (2) These material objects ARE saved with the model, but NOT accessible thru the API.
              (3) When a layer is assigned a texture, it does not appear in the "In Model" Materials Collection, and it shouldas well as allow us to assign a name (thru the layer's material object.)
              In the UI manual mode the new material could be given a temporary name equal to the Layer name, so the user could manually rename it thru the Materials Browser, or we could name it in a subsequent ruby statment like:
              model.materials['Layer3'].name='PolishedWood'
              We should also then be able to go totally automatic thru the API, thus:
              mat = model.materials.add('PolishedWood') mat.texture = 'wood/polished.png' mat.color = [195,144,86] model.layers['Layer3'].name = 'Surface' model.layers['Surface'].material = 'PolishedWood' model.rendering_options['DisplayColorByLayer'] = true
              Later on getting a layer's color, we could do:
              surfaceColor = model.layers['Surface'].material.color
              and setting it to some other color:
              surfaceColor = [127,127,200] model.layers['Surface'].material.color = surfaceColor [*]

              ****** So what we really need is the Sketchup::Layer object's material attribute getter and setter methods exposed in the API, along with the manual UI naming hack.


              EDIT: [* (2010AUG05) Added missing "wish" statement to set layer color.]

                Seconded on the Layers usability, also, it would be great to be able to do:

                Layers.active_layer
                Layers[layer] = active

                A consistent entityID would be awesome. The entity should maintain the ID if it is deleted, and then undeleted as well.

                Pages:

                In addition to retaining information on which layers are on and off, should also be able to retain the active layer for each page.

                              I don't know about that one... Pages are special. Even though you "select" a Page, depending on transition time, Sketchup can be animating somewhere between the previous page and the selected one.
                              A FrameChangeObserver is needed to know when the animation is complete. Only at that point would I 'technically' say that a Page was the "active_page" or "current_page."

                              @Karen. You can get an array of the hidden layers for a Page:
                              mypage.layers
                              so the visible layers would be:
                              my_vis_layers = model.layers.to_a - mypage.layers

                              • why they didn't name the method Page.hidden_layers, I don't know.

                                I like this idea, particularly useful when adding text to Scenes. It seems quite possible using an Observer.

                                But when you add text to Scenes (Pages,) are you drawing to the model, or drawing to the View ??

                                If it's the View, then the active layer does not matter.

                                The active layer is a property of the model. A Scene (Page,) is a View mechanism, which does not "have" layers; it only 'remembers' which of the model's layers to hide or show. A layer also has "new page behaviour" which it can tell new Scenes (Pages,) how to 'remember' their visibilty.

                                I can see some problems for other scripts, if the active layer was automatically changed when a Scene changed. There would need to be some kind of toggle to turn the "auto" feature on and off.
                                In addition, their would need to be scoping. What if an Observer was to be triggered while this "auto layer" feature was on? Outside the current script (or scope,) the Observer may want to "see" or "use" another layer as the active one.

                                It also occurs to me, that we are supposed to always be drawing primitives on "Layer 0", but still some modelers want to draw on other layers (construction lines especially.)

                                Anyway.. we'd need to consider this carefully. It could be a disaster.

                                I'm not here much anymore.

                                  .. as it's a property of the model (Sketchup::Model class.)

                                  see API: Model.active_layer

                                  Layers[layer] = active

                                  Will not work because there is no .= method defined for the Sketchup::Layer class. (You'd just be calling Ruby's internal hardcoded refererence assignment operator, which could set the layer reference on the left of the operator, to any kind of Ruby object. A bad idea, if it doesn't immediately cause an exception.)
                                  This why the .new constructor is "hidden" (or made private,) and we create layers thru the collection class' .add method.

                                  Sketchup.active_model.active_layer=layers['mylayername']
                                  .. again, a property of the model (Sketchup::Model class.)

                                  see API: Model.active_layer=


                                  You CAN get a SKP DOM object's parent by using the .parent method. The model is the layer collection's parent, in the SKP doucment heirarchy. Where layers is the model's Sketchup::Layers class instance:
                                  this_layer = layers.parent.active_layer

                                  But, since each model instance, has an instance of a Sketchup::Layers class object, you'd think it (the Layers collection,) should also know which one of it's elements was active.
                                  A simple Ruby patch for the Layers class:

                                  
                                  class Sketchup;;Layers
                                    unless method_defined?('active')
                                      def active
                                        self.parent.active_layer
                                      end # def active

                                      def active=(arg)

                                    unless method_defined?('active?')
                                      def active?
                                        # .equal? returns true ONLY if receiver and arg have same object_id
                                        self.equal?( self.parent.parent.active_layer )
                                      end # def active?
                                    end
                                    unless method_defined?('current?')
                                      alias_method('current?','active?')
                                    end
                                    #
                                    unless public_methods(false).include?('eql?')
                                      # only override if it hasn't yet been redefined
                                      def eql?(arg)
                                        if arg.class==Sketchup;;Layer
                                          # we shall ignore the name attribute
                                          # use the == override to include name in test
                                          # use <=> to test only the names (match returns 0)
                                          same = true
                                          return (same = (self.page_behavior==arg.page_behavior)) if (not same)
                                          return (same = (self.visible?==arg.visible?)) if (not same)
                                          return same
                                        else
                                          raise(TypeError,'Sketchup;;Layer expected.')
                                        end
                                      end # override eql?
                                    end
                                    #
                                  end # class extension
                                  
                                  

                                  I'm not here much anymore.

                                    I don't know if this thread is still checked by the Sketchup team, but I have one ruby request:

                                    • be able to set selection colour per entity, including bounding box color.

                                    It would allow different kinds of entities to be shown as such.

                                      That's a very old feature request.

                                      I think it was back at v7 I remember seeing members ask for groups and components to be different colours.

                                      I love it to happen. Sorely needed in such a visual program.

                                          does anyone know if any of the remarks here will be taken into consideration in a new version?

                                          The SketchUp development team are famous for marching to their own inscrutable set of priorities, so only they know for sure. But this topic was started by a member of the team, so it is at least as good a place as any for sketchUcation members to post suggestions.

                                            We're watching. 😉

                                            Since the Trimble acquisition a good number of have been addressed. That despite the fact that we've only had short dev cycles so far. Takes time to shift things around. But we're ramping up.
