In this tutorial, you will find a step by step guide on how to create a bevel gear in SolidWorks by using 3D features. I recommend that you play around and try to create different cogs and gears. Since almost all mechanical designs use gears and cogs they are very useful to know. A bevel gear might not be the most normal cog but it’s still a very important part.
