Thanks Jim, Web dialogues worked great! Thank you!

Sketchup tried it... BUT many of us prefer our own methods...

Yes - one always use the English names regardless of what locale the user might have. The Plugins menu is only mission when no plugins has added any menus to it.

MAN U R Genius

http://code.google.com/intl/zh-CN/apis/sketchup/docs/ourdoc/entities.html Important note: If you apply a transformation to entities that are not in the current edit context (i.e. faces that are inside a group), SketchUp will apply the transformation incorrectly, since the geometry has one origin and the current edit context has another. You can correct for this by watching the Model.edit_transform and Model.active_path. See ModelObserver.onActivePathChanged for more information. I put it in the origin and tried, there still is a problem ,the side face of the tube come out of the group(component) with the top and bottom face being still in the group

@unknownuser said: as I dont have 64bit Windows to test it up, take in account this as well - "The %ProgramFiles% itself depends on whether the process requesting the environment variable is itself 32-bit or 64-bit" %ProgramFiles% = ENV['ProgramFiles'] But I told him to use %ProgramFiles(x86)% (which is ENV['ProgramFiles(x86)'],) and should not be present on 32bit systems. On a 64bit system, running a 32bit process (in this case 32bit Sketchup, running 32bit Ruby as a subprocess,) a copy of the enviroment is created for the process. Both the vars ENV['ProgramFiles'] and ENV['ProgramFiles(x86)'] should contain a pathstring that points at the same 32bit localized "program files" directory.

thank you, yes you are right, I used ASP grammar here:( but I find I also used wrong database driver provider, anyway ,I have worked it out.

I study civil engineering and the script is some kind of homework. I'll talk to my tutor in two days. After that I'll know wether I'm allowed to give you the code. Thanks so far. Tim

@ktkoh said: The problem was that some entries were interpreted as strings. UI.inputbox returns values in the same class as you feed the defaults. So if you feed it Lengths it returns lengths.

Just another thought (while browsing around the forums..) depth = width = length = nil File.open("My Documents\\slabout.text") { |fp| depth, width, length = fp.gets, fp.gets, fp.gets }

The erase!() method is defined in class Sketchup::Drawingelement Sketchup::Layer is a subclass of Sketchup::Entity, NOT a subclass of Sketchup::Drawingelement, so it does not inherit a erase!() method. You will need to move all entities off of the layer, then use Layers.purge_unused() BTW.. Layers is a C++ collection, not a Ruby Array.

You could also try to see if using the UI.start_timer block method works for you. This with execute the block immediately, and not repeat: UI.start_timer(0.0,false) { my_calc_method() }

InputPoint.transformation http://code.google.com/intl/no/apis/sketchup/docs/ourdoc/inputpoint.html#transformation Gives you the transformation for the input point. Will probably be useful to you for converting between local and model co-ordinates.

I just test your plugin

layer=model.add("Layer0") does return a reference to a layer in any locale - including EN. It is the same layer as model.active_layer=nil Setting the active layer to nil and getting its name is the foolproof way of finding the default-layer's name in that locale. If you are sure that layers[0] is always the default layer then using that should work too. Then to process all layers except the default-layer you can use model.layers.to_a[1..-1].each{|layer|###do process###} as it misses off the first one...
