In this tutorial, Glen Johnson shows you a technique to model knurling in Cinema 4D. Glen uses some of the modelling tools in ways that they may not have been designed for and demonstrates some pretty neat techniques in the process.
Glen also introduces the Mesh Checking feature of C4D’s modelling toolset. A handy but hidden gem which allows you to check the quality of your mesh, isolate poles, bad polygons, single points and many other useful options. You can also use this for making selections and other creative uses.
