Off topic: @unknownuser said: (1) The word useful has only 1 "L", by the way. thanx for your correction, the English language is not my mother language as you might have noticed.. /Off topic All code is safe now and my code works like a charm, so thanx for your help. And yes I SHALL read the book before I come here and ask questions like this..

An object of what you mean is a Sketchup Drawingelement. If the Drawingelement is a Face, Edge, ArcCurve or Curve, it will have a method to get all vertices, and for each vertex you can get the position (which is what you want): positions = face.vertices.map{|v| v.position} If the Drawingelement is a Group, ComponentInstance of Image, it is "a model" in the model any you have to loop over the contained entities: group.parent.entities.find_all{|e| e.respond_to?(:vertices) }. map{|e| e.vertices.map{|v| v.position} }.flatten or with component.definition.entities

Why are you asking again? I already responded a week or so ago... http://forums.sketchucation.com/viewtopic.php?f=180&t=47043

So there is none? I tried to reload an .rbs (I mean, why not) and the only way so far was to make a temp file and load that...

@dan rathbun said: And the API needs these, and the app needs to use them. Yes - agree. Your idea about multiply two Length to get and Area, and Area with Length to get a Volume is very elegant. I'd very much like to see this into SU9.

@tafkab76 said: That could quite easily be solved by an own "uniq"-method for Point3d-objects Actually - no. #uniq will not compare Geom::Point3d against their positions - but rather if they are the same object instance.

NO problem. Chewin' on it helps. Sleeping on it helps. Brainstormin' helps.

Here is the code which makes this work. If points to the center of the first item in the selection set, then uses SketchUp zoom to selection to do the zoom. It zooms to the third, desired, image in the post previous to this one. def zoom_selection # zoom to selection by rotating camera first model = Sketchup.active_model entity = model.selection[0] if (!entity) do_error("Nothing selected") return end#if view = model.active_view camera = view.camera eye = camera.eye target = camera.target up = camera.up target = entity.bounds.center camera.set(eye, target, up) # point to selection view.zoom(model.selection) # then zoom end#def

Yea, onQuit() has problems under SketchUp. Under OSX it isn't called at all. If you search the forum for onQuit you'll find a couple of threads on the topic. (Sorry, don't have the links at hand.)

I've read UVW somewhere as well. We have to find out more. For UVW mapping Wikipedia says no more than: "the third dimension allows texture maps to wrap in complex ways onto irregular surfaces" A Google search shows UVQ is mostly related with SketchUp, and that the names of these coordinates are not very standardized (just letters in the alphabet before x,y,z), for example there are also Q,R,S,T. There's an interesting explanation on gamedev.stackexchange, that the W allows to optionally apply a transformation matrix before rendering a texture to screen (for example for animating textures without expensive moving of the texture on every entity).

Thanks Dan for the review and changes. I have adjusted my files to include your suggestions and when I have a how to vidio completed I will post in the plugin section. Also I expect to be back for help on putting my Joint Tools under the namespace umbrella as I have just started that process. Keith

Of course you´re right, I only browsed the Entity-Classes, not the Collection-classes, although I already created some faces using add_face...shame on me. thx for your quick response!

Another solution, IF the outer module does not contain instance methods, is to include it into the inner module: module TT_Test module Foo;;Biz include Foo def self.prod puts CHEESE end def self.q p Module.nesting end def self.other p Bar end end # Biz end # TT_Test I've seen weirder stuff in the standard Ruby Lib extensions, than that.

Hi Alex, Your first few posts here are moderated so try not to post consecutively as there is a delay from posting to approval. Hope the conference is fun! Rich

Sorry we muddle you with using edge/line - I always meant 'edge' - never 'line' as in "[point,vector]". Can you at least work out the bounds of what's been made ? Then add some grouped faces with it... Then we can talk again about trimming/not-overlapping them with your edges collection

I wrote a tool that using 'slices' to find an object's [approx] center-of-gravity... You could project every vertex.position in the object down to the surface below as a raytest using Z_AXIS.reverse. The one with the shortest distance to raytest[1] gives the vector to move it down vertically, so it touches the surface as if it were dropped vertically. You really ought to make points along all edges in the object at minuscule centers and test these as a surface might well have a 'bump' that avoids vertices but which would affect the object. BUY another alternative might be to do the nearest vertex drop and do a temp grouped intersect between the two objects, if there's a result then there's a 'bump' that the object should have caught on and you can shunt the object up to suit that,,, Now you have an 'anchor' point of sorts. You know the vector from that 'first point of contact' and the CoG. If it's parallel with the Z_AXIS it's balancing on a pinpoint - but chances are it's not ! So... Rotate the object around the cross of Z-AXIS and that vector by small incrementing angles. Each time do a temp intersect with the surface. If there's a result back up in 1/10 increments until there's virtually none. The object is now on the surface and tilted downwards towards it CoG until it rests on the surface. If the CoG is not vertically on the vector from the 'first point of contact' to this 'second point of contact' then the object needs to rotate yet again - around this vector - again testing for intersections until a 'third point of contact is found'. Now the object is resting on the surface with three points of contact and the CoG is somewhere within that triangle of points - it is stable. If in any of the two points of contact steps the CoG of a vertically aligned with the vector you can choose for a 'dangerous stability' - balanced on a 'knife-edge' - or choose to tilt randomly in either direction until a 'hit' with an intersect give another point that is stable... It's actually very complex as the initial anchor might no longer be on the surface after the second or third tilt !

My solution is more readable. Let me rewrite it, thus: #default intermediate column placement resetfix =( @fix ? @fix ; @flenx/2-@fcol ) if ... # @fix gets changed here end @fix = resetfix # a new if statement; if ... # @fix gets changed again ... end @fix = resetfix # ANOTHER if statement that may change @fix;

@joshb said: Thanks thomthom! That is exactly what I needed to know! Right now users are just going through the SketchUp GUI File, Import to do their work. I'm going to look at the observers, perhaps DefinitionsObserver.onComponentAdded to see if I can do my merging there. Thanks again! Josh Beware! UI import is not the only thing that might import a model. If you react to an observer event you can crash SketchUp. You may also interfere with some other operation. Setting attributes is something that can be undone. And starting an operation in the middle of another one will interfer and break the first one. So if you react to an observer event and modify anything - you might break the undo-stack, you might break an operation of another plugin or native function - or you might even crash SketchUp. My recommendation for observers is to only read data. If you need to react with model changes, cache it for a later time when you know it's safe to modify your model. For instance, you detect a model import, you cache what definition that was and wait with the merge until your plugin need to access any of your data. Another thing: be very careful what your observers do. Make them do as little as possible. Events can trigger in the thousands in some scenarios and then it doesn't take much to bog down a model. Refer to this list of observer issues which I've been trying to chart: http://www.thomthom.net/software/sketchup/observers/

Let's assume your 'box' is a component. Let's assume there is a value 'x' thet you want it to 'remember' for another time... You have a reference to the definition - let's say it's ' defn'... Then this code remembers it: defn.set_attribute("Cheez_Data","x",x) Provided that you save the model the next time you want to access the SKP and that definition - perhaps via a selected instance... like defn=model.selection[0].definition - after you test for it being a suitable instance etc... You could use: x=defn.get_attribute("Cheez_Data","x",0) Here it's set to return 0 if it's not been set before - otherwise it's 'nil'. You can store loads of different data in an object's attribute-dictionary. The data types can be integer, float, string, boolean, array... A hash has to be stored as an array for the 'set'... and reconstructed into a hash after the 'get'. You could attach data to the the model itself, BUT since you are going to change a specific definition you might be best storing it there... You can attached attribute data to most 'types', but some like geometry are more 'transient'...

Yes, it'd return an error or if @ip1 is nil then it might be seen as equal to an empty @pts[] ? If you are testing something that might be nil it's a good idea to check it exists first...
