Here is another model made by me in Sketchup Make 2017. Before commenting, please check out the video discription on YouTube, of which I have explained the reason behind certain books on the shelves of the book case being duplicated. This is no mistake made on my part, the duplication was my solution to solve a problem that I had with making this model.
