Summary
There's more than one way to create a 3D model. The different tools available allow for all kinds of modeling, not just blocky technical parts but clever organic objects that are interesting to look at as well:
Using the skin modifier to create a basic body shape
Using the skin modifier to create an armature
Painting weights and posing the model with an armature
Using the sculpt tool to make a model with tools similar to drawing
Using the decimate modifier to reduce the polygon count of a model
At this point all the most common and powerful techniques for creating models from scratch in Blender have been introduced. The next chapter will focus on how Blender can be used to clean up an existing model to make it ready for print.
