Tnks! All logical and useful

Great Idea, I was wondering how to do that. Done.

Geom::Transformation.new( origin, zaxis ) <- that isn't a rotation transformation. To rotate you must use one of these formats. Geom::Transformation.new( pt, axis, angle ) Geom::Transformation.rotation( point, vector, angle ) https://developers.google.com/sketchup/docs/ourdoc/transformation#rotation But what is not clear is this: "how to rotate an object in the direction of the cursor" What do you mean by this?

@debbie said: @thomthom said: Maybe you can make a Ruby C Extension work for you? Ruby C extension? seems useful! thanks. I made a Hello World project for getting Ruby C Extensions to work under SketchUp: https://bitbucket.org/thomthom/sketchup-ruby-c-extension

OK...it doesn't crash if just before showing the savepanel I put a line of code to show a simple messagebox: then the savepanel shows. Although the messagebox is nowhere to be seen. Then I tried this code: if UI.messagebox("Save results to file?", MB_YESNO) == 6 savePath = UI.savepanel("Save results file",model.path,"Sunlight analysis.csv") # If the user doesn't press cancel; if savePath outfile = File.new(savePath, "w") outfile.write(allResults) outfile.close() end end Now when the execution reaches this point SU suddenly switches program, i.e. as if someone had pressed Alt+Tab. It's still there, but I have to reopen it. And the messagebox still isn't anywhere, hence neither is the savepanel. I just seem to have gotten the UI very confused in general.

Probably the result of dividing by "almost zero". Which in turn could result from a floating point roundoff error.

Weird indeed but moving the prism up 1mm solves the problem.

Dan - the bug came immediately after: if e.is_a? Sketchup::Edge ... it was very strange, and as I said, happened once in a great while - I couldn't figure out how to make it happen on command.

Getting there... When you make a new definition add geometry to it immediately. Empty definitions/groups don't survive in code... Try something like: unless unit_block=def_list["unit_block"] unit_block=def_list.add("unit_block") ### add geometry to unit_block.entities ### add description to unit_block.description ### etc end ### now add instance, knowing the definition exists and has geometry which might be clearer? You don't need to add geometry to the component if it already exists ! Another tip - use Timber.new(bPD,bPW,bPL) not Timber.new (bPD,bPW,bPL) don't leaves a space in front of the arguments' ()

@tim said: ..., for this case as an example, one could actually create a blank page and set it up as needed rather than having a rather cockeyed 'new' message that actually creates, does setup that isn't wanted and then leaves one to work out how much to undo… right now it isn't 'new' but 'copy'. Well we are supposed to be able to do this with the flags argument in the add() method. see page.update() for an explanation of the flags. What it is missing, is a camera argument. It assumes you wish to copy the current view.camera So you have to modify the new page's view / camera after it is created. (It gets set to the current selected page, whether you want this or not.)

@alexmojaki said: Also glad to understand what soft and smooth edges are. For a detailed breakdown of what each property does (soft and smooth has very distinct functions) check out this article: http://www.thomthom.net/thoughts/2012/06/soft-vs-smooth-vs-hidden-edges/

@archidave said: ... Since I was thinking along these lines, I was expecting the attribute dictionaries to behave in a similar way to creating instance variables; ... Nothing is stopping you from doing so. You can create a custom class (within your plugin namespace module,) for a Wall, that has instance variables, that are loaded from an entity's attribute dictionary. If you just save the values as an array, into a single attribute, you can use Ruby's iterator loops or methods, to load the values into instance variables. So the names of instance variables, are defined by a literal array inside your class, an the initialize method iterates this array, matching it's indexes, with the indexed values in the dictionary array. module ACME module BIMinator DictName = 'ACME_BIMinator' class Wall Atts = [;area,;thickness,;paint] attr_accessor( *Atts ) # expand array Atts to parameter list def initialize(entity) @prop = entity.get_attribute(ACME;;BIMinator;;DictName, 'properties') Atts.each_with_index {|att,i| method("#{att.to_s}=").call(@prop[i]) } end end # class end # BIMinator end SO.. the actual attribute names are defined in ONE place, your custom class.

Sample test model?

@dan rathbun said: Just a note, that in playing around (I did not realize this before,) that custom "User" Axes can be saved within a ScenePage. Yea, I often set up Scenes that adjust just the axis. All though, with SU8 now automatically adjusting the model axis to match component axis there's less need of it for my use. Works well when you have a building with axis in various directions.

TIG, your profetional!

There are several Examples of Tool .rb files shipped with Sketchup - e.g. LineTool. These will show how to construct and then call a Tool class, which then has access to lots of methods relating to user input - mouse, keys etc - without you having to reinvent them from scratch... Also see the API docs... https://developers.google.com/sketchup/docs/ourdoc/tool

@thomthom said: You're aware of the API documentation, right? https://developers.google.com/sketchup/docs/classes The Entities class has many method to add entites - depending what you want to add: https://developers.google.com/sketchup/docs/ourdoc/entities You're not talking about adding an existing entity to a different Entities collection? I am sorry I made a mistake about the concepts of Sketchup::Entity and Sketchup::ComponentInstance. I have two car models, and I should use entities.add_instance to add a car.

@tig said: If you meant ComponentInstance then they each have bounds. Make a new empty bounding-box object [ bb], and then add each of the instance.bounds to that bb.add(instance.bounds). The center is bb.center......... Thanks for your tip. I will test the code.

Duke, ya need to get your files and folders organized (so you stop using global variables.)
