Hi , I tried to adapt from the comment in my code , but it doesn't work yet for clicking lines then load external reference component (0,0,0) from component's file. I'm still finding how to link between the functions that the model can stretch or scales the component to the length as the edges. Here's my attached ruby , not sure what's error in the code as I'm a new to ruby ! Any suggestion , I would be appreciate!. Thanks

@dan rathbun said: @thomthom said: But when I have inspected .skp files I saw no duplicate of any attributes blocks - and the attributes data blocks where in UTF-16. I wonder if we could use Zlib to compress data before writing it to dictionaries ?? I'd love to be able to use zipping in my projects. Think I looked at it some time ago and people had tried to find ways to make it work properyl within SketchUp ruby with mixed results..

Thanks, Thomthom . I'll follow your advice.

@thierry_st_malo said: It works for the red and the green axis, but not for the blue one. Ridiculously, I can't see why. What you explain more what "doesn't work"? Exactly what happens, and what did you expect? Any errors?

Putting this on the back burner until I get some feedback.

@thomthom said: Do you stuff in the Tool's activate callback. That should trigger after deactivate. Initialize triggers when you create the tool instance - not when it's activated. You can reuse a tool instance - where activate is the one that will trigger when your tool activates. (How do you activate the tools btw? model.select_tool or model.tools.push_tool ?) Hi Thomthom. Man, such a stupid error of me. I did use the initialize method instead of the activate method. Btw, I use select_tool ToolName.new Thanks for the answer, funny I didn't saw the error myself

You have to save the view's camera properties to a new Sketchup::Camera instance, then restore it. view = Sketchup.active_model.active_view vcam = view.camera props = [vcam.eye,vcam.target,vcam.up,vcam.perspective?] cam = Sketchup;;Camera.new(*props) view.zoom_extents view.camera= cam

Mistry with win7 zip files solved!!! Some how my folder option to hide known extensions was selected and this created the problem making a ziped file a ziped folder. I know I had nothing to do with that change as it took me a long time to find Folder Options after I started looking for them. Keith

I wrote this last year http://forums.sketchucation.com/viewtopic.php?p=371243#p371243 'ShadowProjector' If calculates shadows cast on faces and % area etc [image: lCSs_ShadowProjector_Example.PNG]

If that's Ruby, then I love Ruby too! Thanks Dan. I perused the book, and as someone who hasn't a clue it looked to me like it is well written, and should be easy for the beginner to get a grasp.

Yes it should, and now is. Updated the code. (I was uniq!'ing in the calling methods, and at the last moment replaced several in those methods, by adding the .uniq! to the return statement. I did think about which uniq to use, for a split-second, and didn't want to create a new array object, so I added ! to the end. That's what happens when ya' rush.) Thanx for the check TIG!

Did you read the "linetool.rb" file in the "Examples" directory ??

Here's a start. Rename the module or cut & paste the proxy class block into one of your modules. module Sort class << self def sort_faces_by_vertex() @sel = Sketchup.active_model.selection.to_a @sel.delete_if {|e| not e.is_a?(Sketchup;;Face) } @sel.sort! {|a,b| ([a.vertices.min{|v1,v2| v1.position.x <=> v2.position.x }.position.x, a.vertices.min{|v1,v2| v1.position.y <=> v2.position.y }.position.y] <=> [b.vertices.min{|v1,v2| v1.position.x <=> v2.position.x }.position.x, b.vertices.min{|v1,v2| v1.position.y <=> v2.position.y }.position.y] ) } end def assign_room_nums_to_faces() sbv = sort_faces_by_vertex() sbv.each_with_index {|face,i| dict = face.attribute_dictionary('Properties',true) dict['name']= "Room #{(i+1).to_s}" } end end # proxy class end # module Sort

@sdmitch said: There is always a way but at what cost. The code would no doubt expand from 3 lines to 3000. I'm on a framerate sensitive medium, so anything I can do to improve frame rate would be useful. It would be great if you have any tips on how to set the LOD for the miniature.

@thomthom said: @dan rathbun said: So mitcorb, no you can NOT edit them by accident when they are hidden (singly or globally.) All though they still update. Yes.. if associative and their anchor points are moved or changed. I'm not sure about styling fonts, etc. I suppose you can still access them via an entities collection... and I wonder if you could FORCE them into the selection set without crashing the application.

so I take it I'm covered with Your cleanup tools... kool.

FYI... I have a bug issue logged that Sketchup::read_default() cannot return DWORD values. Basically the method assumes anything you want to read was written with Sketchup::write_default(), which inspects objects into evaluatable strings before storing them. So.. Sketchup::read_default() is stupid and always tries to run the stored values back through Ruby's eval() without Type checking. When a error occurs it seems the method's rescue block just returns nil. So you'll need to use the WIN32OLE class ("win32ole.so" file,) and the Windows Scripting Host interface to read registry values. See: [Plugin Library] Win32API and Win32OLE so files

I note there are 7 other settings that are positive, and begin with the prefix "Display".. and one positive that begins with the prefix "Show"... The lack of convention is annoying.

@thomthom said: That seem to work perfectly! Excellent! 4 trys is the charm. Man, I love Ruby's flexibility!
