Face Extrusion Modeling
Face Extrusion Modeling is often referred to as Box Modeling. Modeling often begins
with the Default Cube, which is then extruded to form the model. But, you need
not start with the Default Cube. Other Primitives are often used as the starting
point, in particular, the Plane, Circle or Cylinder. This method usually relies heavily
on the Extrude Tool.
Starting with the Default Cube and modeling by Face Extrusion is probably the best
approach to creating buildings (e.g., houses, stations, etc.).
