A couple of years ago I wrote an overview of definitions and instances in SketchUp: http://www.thomthom.net/thoughts/2012/02/definitions-and-instances-in-sketchup/

Export / Import DAE files are XML. You can select what you wish to save, and call: model.export( "some/path/filename.dae", optshash ) Create the options hash first with :selectionset_only => true Then import them using model.import

Thank you AdamB. I did add the path of the downloaded .dll and .lib to the VS library search path. Somewhere I read that character encoding differences could cause such error messages. So I also tried to change the project's encoding settings without any luck.... EDIT: Thank you. SUCCESS!!! (Well it was a missing reference to the lib... )

And this is how it looks like on nVidia with AA enabled: [image: 2014-07-02_23h02_32.png] [image: 2014-07-02_23h04_12.png] [image: 2014-07-02_23h04_33.png]

Thanks for all. The problem is done. The solution is to use ultraedit convert function(convert ascii to utf-8(unicode edition)). Originally, i use the notepad++ to convert utf-8 without BOM, and it seems not work as expected. Now, the split function can work correctly without any force_encoding, but the input from html should be converted using force_encoding("UTF-8"). Thanks again for TIG.

@aerilius said: Geom::Point3d.== method checks for example if all coordinates (x, y, z) are equal, and then says two points are equal. uniq appears to check for identity and not for equality. In Ruby 2.x (SketchUp 2014+,) where we now have a block form of the uniq method, that we can tailor to override C internals of the uniq! method, and tell it what and how to do the comparison. Ex: pts = roof.uniq {|a,b| a.==(b) } or: pts = roof.uniq {|pt| pt.to_a } In the future, perhaps, custom uniq methods could be added to a new PointArray subclass of Array., for the API. Of course any author could create such a custom class within their own namespace(s). ALSO.. the many od the API classes should have had their eql?() method aliased as the overridden ==() method. The uniq methods want to call eql?() instead of ==().

hi, thanx! work like a dream, as soon as i found out, that a ng - group must be created before calling the method, then it moves both groups into it. fantastic! THANK YOU !!!!! stan result: g0 = @group_floors #COMES FROM ANOTHER METHOD g1 = @facade_group #COMES FROM ANOTHER METHOD ng = model.entities.add_group self.insert(ng, g0, g1) ##*************************************************************************** def self.insert(ng, g0, g1) ##*************************************************************************** ng.entities.add_instance(g0.entities.parent, g0.transformation) ng.entities.add_instance(g1.entities.parent, g1.transformation) g0.erase! g1.erase! #ng.name = "master house group created" count = 1 entities3 = ng.entities entities3.each { |entity| if entity.is_a?(Sketchup;;Group) entity.explode if count == 1 #SO GROUPS ELEMENTS ARE AGAIN AT LEVEL 1, as needed count = count + 1 end } end

got it! thanx, works perfectly... stan

hi tig, understood and done, works perfect, the combi-version is very nice and confortable and i can pass arguments to it from any method. you will then see it in the finished ruby! thanx a lot for the explanation. stan

You have to make a 'class'. SketchUp recognizes it as a 'Tool' from the way it is made into a command... Special 'Tool' methods can be used in that class... Go to the Extension-Warehouse and find the Examples - the 'draw box' example shows how to set up a Tool... https://extensions.sketchup.com/en/content/example-ruby-scripts

@tig said: ...an older version... BLAST! Thanks TIG. Started a while ago and completely forgot about the updates. Starting over LOL

Get the "container[s]" of the entities, get their "transformation[s]", then transform the vertex's point to match. Then you'll have the point in the model coordinate system, not the point in the container's coordinates system... This will give you the path through the nesting: http://www.sketchup.com/intl/en/developer/docs/ourdoc/model#active_path See these methods to get the 'accumulated' transformations of each container: http://www.sketchup.com/intl/en/developer/docs/ourdoc/transformation

hi tt_su, super, soft & smooth helps to identify. it works. the selected field of mesh is tranfered to a single face (i work with selection). thanx stan

get_center2d() and get_scale2d() C++ SDK functions return a camera shift and zoom-in factor for 2p perspective camera. You reply gave me idea, that maybe I could calculate the shift/zoom using InputPoint.position... This may work.

You have a component definition [ defn]. You have an instance of it [ inst1]. That instance has a transformation [ tr1=inst1.transformation]. That transformation has an origin [ org=tr1.origin] - i.e. its 'insertion point'. You make a new transformation based on that: tr2=Geom::Transformation.new([org.x, org.y, org.z+z_increment]) Where the ' z_increment' is the amount by which you want to move the copy upwards - either in inches or a Length. You add the copy thus: inst2=inst1.add_instance(defn, tr2)

@tt_su said: Ah! Found the crash report. ... I'm logging a new issue.

You could theoretically read the screen dimensions using JavaScript, divide by two and subtract half of the dialog's width and height (you can read the inner width without window border using JavaScript). This is not recommended. If it is not essential to the functioning of you plugin, think again if you can get along without it. This causes your dialog to launch initially with different dimensions and then "jump". On a multi-monitor setup, you don't know whether the dialog is on the second monitor, and the above formula will give you coordinates for the first monitor. The dialog will jump to the first monitor, if it was launched (by registry preferences) on the second one.

@jolran said: Bottom line is the crash does not occour when using GL_LINES. So for me all is fine.. We'd really like to close down any causes of crashes. So please send us examples if you come across it.

Yes, Thanks. I used that and noticed some increase in performance. But I have kind of abandoned the PolygonMesh for now. At least during the previewing state. I experimented building my own meshclass with indexing of points. Instead of using PolygonMesh class as a Point container. Keep arrays of indexes and a Hash containing Points. And the Transformation only deals with the uniq points(Hash) then. Quite a lot of speed improvements! The advantage here is that I can reuse the objects somewhat, while I can't purge/clear(?) a PolygonMesh. So the GC should work a little less. I'm sure you guys have/are doing something similar or more advanced...

If you are in the root context then you can't. If the user has set a custom axis then there is no Ruby API method to obtain that. We have that logged as a feature request.
