ABSTRACT
Blender Incorporates many techniques for performing a variety of functions some of which are automated. The automated techniques can be considered as Tools. Like any trades person, mechanic or engineer knowing what tools are available, how each functions and most importantly what tool to use for a particular application is the key to success. And, yes, where to find the tool. The Knife tool allows one to cut across edges on the surface of a mesh Object and insert vertices at the intersection of the cut and the edge. The cut creates new edges and faces. The new vertices, edges and faces can then be manipulated to remodel the mesh. In Blender, Objects are constructed from a Mesh. Different Objects can be joined together to make a single Object. The Objects may be separated under certain conditions or parts of a mesh can be separated from the main Object.
