As you model your objects, a common fault often creeps in – more than one vertex on top of each other. This happens in various situations but most commonly when an extrude, or scale operation is abandoned. Vertices on top of each other are invisible, yet they can play havoc with model shading.
Every flat surface has a normal that points outwards at 90 degrees to the face. Every bevel has its own normal for each face segment. When smoothing is applied, Blender tries to average out the adjacent normals to provide the illusion of a smooth curve. The problem with this is that a large flat face next to a small thin bevel will be influenced excessively by the bevel’s normal…
A Bounding Box is defined as the smallest rectangular box the object can fit in. All internal angles are 90 degrees.
How do you adjust your view of the model you are working on quickly? These tips get things done quicker:
Destructive modelling is a workflow where an operation cannot be changed later whereas Non-destructive modelling allows you to modify your operation at any time..
Provided you don’t perform any other action or create anything if you press F9, the last parameter panel pops up again allowing you to modify your last action or creation.
