Thanks, works perfectly for me - every component is on its own layer and CNC machine can read layers automatically for toolpaths.

@tig said: @masterpaul said: Thank you I understood how to load a single plugin, and did so successfully but not so much a whole file from this directory: E:\Sketchup\Plugins Inside my example script the last few lines of code load everything inside a given folder. You can't type multi-line code in the console, use ; to make it one line... First set the path path='E:\Sketchup\Plugins' then Dir.entries(path).each{|file|ext=File.extname(file).downcase;next unless ext==".rb"||ext==".rbs";Sketchup.load(File.join(path, file))} To load all files inside the give 'path'... Ah thankyou.. it works perfectly

Well done, Terry!!!1 Although its not something I use often it is a very well put together toolset!

That DAE export thing isn't a bad idea, it would certainly be a good way to diagnose a bad model... I'll have to try that...

@unknownuser said: When you say fit onto a shape, do you mean surface or single face? I figure it is a single face that could be in various shapes. I would be keen to look at what you have. cheers...Wayne

The built-in guide-delete tool removes all guides from the current context downwards. So if you are in the model context and run it then all guides go. If you are inside a group context and run it then all guides inside the group, and inside other groups/components that are inside the context group, will be deleted, but guides outside in other groups or the model itself are not removed. Note that locking a group or having guides on 'off' layers, does not prevent those guides being deleted in en mass. Of course you can erase individual guides using the Eraser tool or selecting them and using 'delete'... There are several script tools to erase guides in different contexts, and also differentiate between guide-lines and guide-points...

A Point3d behaves much as an Array and vice versa. You can make a point and adjust it's x/y/z values on the fly just as you can with an Array. So pt=Geom::Point3d.new() or even pt=ORIGIN.clone gives you Geom::Point3d.new(0, 0, 0) then pt.x=123.4 OR pt[0]=123.4 gives you Geom::Point3d.new(123.4, 0, 0) A point or array will take .x ,y and .z; as well as [0], [1] and [2]... This lets you read AND set values... pz=pt.z returns 0.0 and pt.z=1 gives us Geom::Point3d.new(123.4, 0, 1.0) etc... I suspect you are over complicating things... To get the z axis of the current 'container', test if it's the model, and if so use Z_AXIS; if not use the container.transformation.zaxis Let's assume we have an object in a container that is called 'obj' if obj.parent==Sketchup.active_model z_axis=Z_AXIS else#it's a group or component z_axis=obj.parent.instances[0].transformation.zaxis end IF you already know where the 'obj' is - e.g. you've made it inside a 'group' then it's even easier... z_axis=group.transformation.zaxis

Thanks for all the help. It is much appreciated.

Having a hard time now. Rarely is anything being sprayed, no matter the setting. No groups or components on the receiving end. FloatDomainError? [image: 0KeM_componentsprayfail-1.JPG]

Thank you Pixero - that helped a lot because as i went back to play i found out what was driving mad... (really i had given up on this! ) when you add the second scene, it doesn't save these, (since it duplicates the photo-matched) [image: dLHp_scene.jpg] switching these on, i can move through different scenes and keep the axis put...! might do a small tutorial later today if i have time..

This was written in 2012 for SketchUp v8 when Windows 7 was current. Please do not PM me in 2019 and tell me it does not work for current SketchUp versions. Things change as OSes and applications are revised. Hold up a min! I Found a workaround to force SketchUp to use Windows MRU paths... ...[ drumroll ]... 1) Open a File Explorer and create a "dummy" folder "C:/dummy" 2) Open SketchUp.. goto "Preferences" > "Files" panel. Click the browse Folder button and choose this empty folder. Your Models path should say: "**C:\dummy**" 3) Close SketchUp. 4) Delete the "C:\dummy" folder. 5) Restart SketchUp. It will now use MS Windows saved MRU paths for "*.skp" filetype. .. No custom button or menuitem needed. This was written in 2012 for SketchUp v8 when Windows 7 was current.

Most probable it's because it's not compiled to work with SketchUp Ruby. (Is it even a match for SketchUp's version? 1.8.x?) One possible cause for the crash could be that it is not compiled into a flat namespace. See my SketchUp Ruby C Extension Hello World project for notes on compiling for SketchUp Ruby: https://bitbucket.org/thomthom/sketchup-ruby-c-extension/src/5c9eb31c541b/src/Example%20-%20Hello%20World/extconf.rb @unknownuser said: <span class="syntaxdefault">  </span><span class="syntaxcomment"># Must be compiled into flat namespace. Otherwise SketchUp Bugsplats.<br /></span><span class="syntaxdefault">  CONFIG</span><span class="syntaxkeyword">[</span><span class="syntaxstring">'LDSHARED'</span><span class="syntaxkeyword">]</span><span class="syntaxdefault"> </span><span class="syntaxkeyword">=</span><span class="syntaxdefault"> </span><span class="syntaxstring">'cc -dynamic -bundle -undefined suppress -flat_namespace'</span><span class="syntaxdefault"> </span>

maybe fredoscale stretch? (but yeah, more info required )

Many thanks. For some non-obvious reason, I didn't even SEE the screen_coords method of the View object. I was looking for an equivalent method or property of the point itself. Gratefully.... John MCC

Interesting posts!

Or this post ? else the Thomthom Ray tracer / Components by Bounds above works very fine but without image from you I have some difficulties to see what you want Components or groups must be horizontal above the object before the drop ! [image: KaRl_bounds.jpg]

problem was nvidia nview desktop manager

Tricky uses of the Tig's plug!
