Hi, when I try to install it manually it dosen't appear in the Extension Preferences Window, and every time i open sketchup again this error appears:
Error Loading File SectionCutFace.rb
Error: #<NameError: uninitialized constant TIG::SectionCutFace::DESC>
C:/Users/Graça/AppData/Roaming/SketchUp/SketchUp 2015/SketchUp/Plugins/SectionCutFace.rb:50:in <module:SectionCutFace>' C:/Users/Graça/AppData/Roaming/SketchUp/SketchUp 2015/SketchUp/Plugins/SectionCutFace.rb:17:in module:TIG'
C:/Users/Graça/AppData/Roaming/SketchUp/SketchUp 2015/SketchUp/Plugins/SectionCutFace.rb:15:in `<top (required)>'

If i try it by the pluginstore and auto install it, it says: Error, can´t unZip.

Can you help?
Regards
