Hi I bought a model from a third party that was almost all tri's. When subdivided, it caused lots of non smooth surfaces, so I manually removed the 'extra' diagonal, to form tri's. Easy but time consuming - Is there a tool/algorithm or easy way to this? I didn't find the right solution from the internet.
