About this 3D model

I like this building. I'd like to make it as a puzzle, just a bunch of beams artfully stacked. It's now the China Art Museum. https://en.wikipedia.org/wiki/China_pavilion_at_Expo_2010 UPDATE: the current model is not accurate. For one it has the wrong number of beams, as can be seen by looking at photos: https://plus.google.com/117398944251193891719/photos Thie model is based on a model found in Sketchup's 3D Warehouse: https://3dwarehouse.sketchup.com/model.html?id=1f68f44ca8e725e980b75d0d464eec35 I don't know if there is any copyright restricting use. I removed a bunch of surrounding stuff and exported it to `.stl` from Sketchup using this extension: http://www.guitar-list.com/download-software/convert-sketchup-skp-files-dxf-or-stl Not sure why there's still a platform underneath. Just a beginner at Sketchup...
