The Ace highlighter looks very good, too. Great to see a few of these popping up now. However, I just fixed my Ruby editor up with Codemirror, so I am not moving... I'll have an updated version of my editor ready after a bit of testing. Here is a picture for now: [image: 5MTg_2011-04-08_1623.png] Cheers, Alex

@thomthom said: Callbacks from WebDialog Javascript under OSX is asynchronous - so sending multiple callbacks rapidly will eat some of the messages. You'd have to have a messagepump system to verify each message is received by Ruby before sending a new callback from Javascript. Do you know if anyone has yet managed to build such a system? I searched around a little on the forums and all I could seem to find was stuff like this: http://forums.sketchucation.com/viewtopic.php?f=180&t=22698 The javascript code in the Dynamic Components folder shows what seems to be one half of such a system, and thus gives a bit of a starting point, but it would be nice to have something a little more substantial to start from...

@zane said: That's great! Thanks Dan and Chris No problem, I fixed a mistake in the done=() method of the second example (above.)

thanks TIG you are beginning to show me how skp REALLY works so i think i can move my camera (accurately) a little closer by a combination of the above info - i can tell skp where to put the camera, fog start and fog end precisely using coords and these 'commands'

I see. Thank you,Tig!

I'm not sure what you're trying to achieve... This might help [a bit] - it traps errors .......... class MyEntitiesObserver < Sketchup;;EntityObserver def onChangeEntity(entity) width = entity.bounds.width.to_f model = Sketchup.active_model entities = model.active_entities pts = [] pts[0] = [0, 0, 0] pts[1] = [width, 0, 0] pts[2] = [width, width*2.0, 0] pts[3] = [0, width*2.0, 0] begin face = entities.add_face pts face.add_observer($mmmmmmmmmmmmmmmmmmmmm) entity.edges.each{|i| i.erase! if not e.edges[1]} rescue puts 'error' face.remove_observer($mmmmmmmmmmmmmmmmmmmmm) face.add_observer($mmmmmmmmmmmmmmmmmmmmm) end end end model = Sketchup.active_model entities = model.active_entities pts = [] pts[0] = [0, 0, 0] pts[1] = [1, 0, 0] pts[2] = [1, 2, 0] pts[3] = [0, 2, 0] face = entities.add_face pts $mmmmmmmmmmmmmmmmmmmmm=MyEntitiesObserver.new() face.add_observer($mmmmmmmmmmmmmmmmmmmmm) I suggest you rename your observer as something less obvious... i.e. others might have used it !

I posted a blurp at the bottom of the API page: @dan said: Model.add_note returns a Sketchup::Text object associated with the View (has no point, leader or arrow.) [ie, there is no such object class as Note or Sketchup::Note.] Bug: (on PC as of v7.1,) The note (Text object,) will NOT be displayed if there are no other DrawingElements to render. A note added to an empty model will not be displayed until some element is added to the model. If all other DrawingElements execpt the note are deleted, the note will NOT be displayed (but is still in the Entities collection.) So modify the previous example: mynote = model.add_note "test", 0.1, 0.1 ... later in the code, delete the Sketchup::Text object referenced by mynote mynote.erase! or Sketchup.active_model.entities.erase_entities( mynote )

Thanks TIG. TT - I revisited your observers chart page after posting the initial message. Definitely very helpful. Thanks for maintaining it. -- Karen

Thank you very much for your reply. Unfortunately, I do not have a lot of experience with this kind of stuff so I might need some more guidance

all good now. I'll download the ruby book. Thanks dan.

Thanks! I found the essential step in your code ( TT::Face.corners( e )). It seems to work for me just fine when I change the order of the points to (the array c contains always exactly 4 points in the same order). pt_array[0] = c[0] pt_array[1] = Geom;;Point3d.new(0,0,0) pt_array[2] = c[1] pt_array[3] = Geom;;Point3d.new(1,0,0) pt_array[4] = c[2] pt_array[5] = Geom;;Point3d.new(1,1,0) pt_array[6] = c[3] pt_array[7] = Geom;;Point3d.new(0,1,0)

Thanks. Now I know where to start.

I'll be there. Its a little over an hour away for me, but I think it will be worth it. And its always fun to meet up with other SU users and talk about SU. It'll be good to see you again Rich, Chris

Works great, thanks.

Thanks, I will have to remember how to do that:)

oh, ok, great. thank you!

I have a similar workflow to what your describing but I use photo match and no ruby scripts. Set the view you want, save it at the screen resolution, edit it, then start a Photo Match session using the new image. Everything should line up perfectly as long as nothing has changed. Finally, just project the photo onto the elements of the model using the option on the Photo Match Dialog.

Thanks Dan. As explained my example is just an example - you need to tailor it to you needs so 'f' >>> 'machine' with the .3ds added etc... In you example it much more difficult to read than mine. Your 'processing' is inside the if...end test when rotation is set, BUT my way will work with less likelihood of massing up - you simply gather the 4 lines of data as I show and use the references you set from them to do your processing for each 'machine'...

@zps222 said: Hi, Dan, I simply paste "module MyTopLevelNamespace" in to Ruby console window of SU, but the error comes. So why? A module definition is a block statement. It's meant to be read by the interpreter. The console is a line evaluation function. You CAN make a module at the console by putting it all on 1 line, like: module Zps222; def say_hello(); puts "Hello!"; end; end YOU are supposed to choose YOUR OWNidentifier for a toplevel module name (namespace.) Replace "MyTopLevelNamespace" with a unique name that YOU decide. (You can use Zps222, or whatever you want, as long as it is unique for YOU, and noone else will use it.) Also "MyPlugin", you change it to whatever name you want your plugin to be. @zps222 said: By the way, can I use eclipse to run your code? Yes. This code is not Sketchup specific. It's just plain old standard Ruby.

By the way... if YOU are creating the files.. why not simplify things and write out CSV records, where each line is: "string tag",x,y,rot We have a topic on reading CSV text files: [code] reading a CSV file EDIT: Oh you are using MatLab written files, as in this post http://forums.sketchucation.com/viewtopic.php?f=180&t=35961&start=30#p319047
