In this 3 part series we will look at some of the fundamental concepts behind using the edge-copy modelling technique to model a face. We will also look at the importance of setting up good reference planes to model from, as well as important considerations to ensure sound topology. If you have some experience modelling already in 3D, regardless of what software you might use, the concepts here are universal and will apply to any software package.
