Thank you very much!

I had SketchyPhysics in my Plugins folder. I removed that plugin (I don't need it for my actual project) and Lamella Roof works fine: it's a great plugin.

Hi Tim,

Your plugin seems very nice, however I've a problem in executing it.
After the two windows for the parameters (I leave them as default), the plugin stops working, no drawing is produced and the Ruby Console shows an error as follows:

@unknownuser said:

Error: #<NoMethodError: undefined method make_unique' for nil:NilClass> C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/lamella_roof.rb:289:in lamella_roof'
C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/lamella_roof.rb:1038

I'm using SU 8 and the new version of your plugin.

Is something wrong with my SU preferences? I've a lot of plugins loaded.
Let me know how to solve the problem (I'm not a programmer).

Thanks
