@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...

Awesome, thats exactly what i needed! Have a great sunday!

I do it that way all the time.

Thanks for the immediate reply.

You should always be running your code within your OWN namespace, so using a global variable is NEVER needed. I use @@ module vars to hold references to observers. YES you can write a method within your observer class that can remove itself. I do this sometimes, and it is really just a wrapper for the remove_observer() method. This example assumes your using your Observer in a Singleton manner: class MySelectionObs < Sketchup;;SelectionObserver @@watched = [] def attach(selection) raise(TypeError,"argument is not a Sketchup;;Selection object.") unless selection.class==(Sketchup;;Selection) if selection.class==(Sketchup;;Selection) && (not self.watching?(selection)) selection.add_observer(self) @@watched << selection end end def dettach(selection) raise(TypeError,"argument is not a Sketchup;;Selection object.") unless selection.class==(Sketchup;;Selection) if selection.class==(Sketchup;;Selection) && self.watching?(selection) selection.remover_observer(self) @@watched.delete(selection) end end def verify_watchlist() unless @@watched.empty? @@watched.delete_if {|e| e.class != Sketchup;;Selection } @@watched.delete_if {|e| !e.model.valid? } end end def watching() verify_watchlist() return @@watched.dup end def watching?(selection) raise(TypeError,"argument is not a Sketchup;;Selection object.") unless selection.class==(Sketchup;;Selection) verify_watchlist() return @@watched.include?(selection) end ### define your other callback methods ### end # class ONE BIG EXCEPTION : NEVER dettach (remove) observers within the onQuit() callback of an AppObserver subclass instance !!

@dave r said: Patience. The author has always updated it in the past. I'm sure it'll get updated soon. yes, version 12 which works until 10 april 2012 was released. http://www.tensile-structures.de/sb_software.html and taking system time back worked for me for last 2 days.

For yery corrupted collada files, there appears just a messagebox "import failed [OK]". The ruby console does not display any exception but just true``. For some collada files, SketchUp says there is a chance that the import could fail and asks if I want to continue [yes]/[no]. If I click yes, it succeeds to import it anyways, if I click no, the same messagebox appears "import failed [Ok]. In all cases, the console says true. I tried it with begin ... rescue ... end without success. model.zip

hmmm... ok. in this case i don't understand why the lines behaved like that. not that important. ok, thanks to you once again.

Soap Skin & Bubble expried yesterday. what to do?

@shirazbj said: Heard of regular expressions before, This time I tried to understand it. Thanks. Regular expression are simultaneously very useful and painful to work with. There is a great quote by Jamie Zawinski which goes "Some people, when confronted with a problem, think “I know, I’ll use regular expressions.” Now they have two problems." I first ran into them at Dive into Python 3 which gives a couple simple case studies and although the language is slightly different the regular expressions are basically the same. Looking at the regular expression given by /[-|+]?\d.\dE[-|+]?\d\d\d/ we have the / on each end marking the start and end of the expression. There are two blocks of [-|+]? which matches an optional + or - sign. I would read this is "0 or 1 instances of + or -". Then we have \d.\dE which matches a single digit, then some arbitrary number of digits until it find an E, then we again have an option sign followed by exactly 3 digits. So this pattern will match a single numerical value in the string given. The .scan method then constructs an array out of every match. From here you can wrap blocks in parenthesis to create groups so you can break the matches up into their own arrays which is what I had done originally until I realized Ruby would parse scientific notation with the .to_f method.
