@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.)

Thanks for your answer TIG, using non modifier keys is indeed a bad idea inside a tool, because they are already bound to lots of different tools. I also discovered that the int values corresponding to keystroke can be accesed like this valueFor_W_Key = ?W a bit weird, but it works. I ended up not using keys

Most of the native tool ids are defined as global constants, that begin with "CMD_" List them, at the Ruby Console: Object.constants.grep(/CMD/).sort The tool state integers vary from tool to tool, and some tools do not use them at all.

There are already several Ruby bindings written for curl. http://rubygems.org/search?utf8=%E2%9C%93&query=curl Maybe one could be made to work under SketchUp ??

The string you feed create_makefile should relate to the init function in your C extension. As you see from the Hello World example, extconf contains this: create_makefile( 'SX_HelloWorld' ) And in the C source you have the init function: void Init_SX_HelloWorld( void ) Note how "Init_" is prepended of the name you feed makefile - and it's case sensitive. @anton_s said: change the vcvars32.bat path to your current vcvars32.bat path, and run it to compile. I have found after making the tutorial that it is easier to just launch the command prompt shortcut that ships with Visual Studio. It's there in it's folder in the start menu. The environment is set up automatically.

The object's 'position' is relatively easy to find - it's just the t=object.transformation.to_a for the xyx point as an array of the last few elements thus: point=[t[-4],t[-3],t[-2]]... OR transformation.origin ! The transformation's scale and rotation interact with each other, so they are much more complex to extract from the transformation array... but not impossible - there are already some earlier post discussing this...

When I first listed the methods, I thot for a moment (until I looked twice,) that the seventh method was named eat_me! ...

Now you understand how to debug! Missing _item ... ...@KSORsubmenu.add**_item**... My typo - which occurs twice when the item is added to the submenu [or it wasn't thanks to the typing error ] Edit those two 'add' lines in your script and it should then work. I have edited the original post so other browsers won't get confused...

Thx to Aerilius - very usefull explanation !

Sorry for the late reply. So basicly what I want to do is upload files to and from a restful api using multipart/form data that are not in sketchup format. ie, export obj file > upload to server > delete obj file or download stl file > import to sketchup > delete stl file after giving up on net stuff through ruby which all seemed to crash sketchup I started looking into accomplishing this through the web dialog with ajax. While it works for communicating with the api in other ways and solves a lot of my problems. It is still not possible to upload or download a file with out the file dialog (and for good reason) but I want something more seamless. So far the closest thing I have found is https://github.com/danawoodman/google-sketchup-file-downloader but it isn't working. Thanks for your help, I will keep at it and appreciate any more help Thanks!
