Maya is an tool with high productivity once you get used to the short cut keys. Memorizing short cut keys is the key to master Maya. Therefore ‘S’, Short cut keys are very important. The second tutorial, we start with modeling by NURBS Components. NURBS is a good choice to build organic form. There are different expression in continuity to demonstrate the curve. And Tolerance is a property to determine the object is closed or not. And size will affect the gap between the faces. When you scale up the object and the gap will become larger. The system may not treat it as a closing face base on the tolerance setting. That is why we should build larger model and do not scale it up. After that we have spent some time on sculpting, snap tools and deformer. Both are different ways or tools to build model.
