It would appear that my model is suffering from multiple problems. I am proficient in Illustrator and Sketchup, but Blender is a bit overwhelming my first time in. First, the main logo consists of just under 300K vertices, most of which are completely pointless. Is there some tool I can use which will automatically eliminate vectors which do not create an angled face? Second, I followed the tutorial to resolve the non-manifold error, but my entire model (all 300,312 edges) are selected. Perhaps there is a tiny hole somewhere in my shape, but I can't find it. Is there a script or easy means to locate that? Thanks!
