Hey, all.  I was in the process of modeling an apholstered chair model, which required some simple sewing buttons to add detail to the surface, and it occured to me the many variety of techniques in which I've seen people model these objects.  So, I thought I'd post this quick step-by-step tutorial showing ONE way to quickly model a simple, but effective, button object that is made of 100% quadrangular topology, without using Booleans, or any mesh cutting tools (except to delete faces).

This is just one way I like to go about it when I need to create a custom button really quick, and wish to maintain a quad-based mesh.  I'll be using 3dsmax 2012 for this tutorial, but keep in mind the topology output generated by this technique is clean and efficient, using standard polygon modeling tools, and should translate to any capable modeling software.  Again, there may be other ways to go about this, depending on the tools in your modeling application of choice; like starting with a cylindrical cap, using scripted plugins, etc.  This method, unlike some of those alternatives, helps to avoid pole distortion, and maintains clean UV's, if you need to add textures.  So here we go...
