Creating a spiral Christmas tree design, Part 1: modeling

This tutorial shows how to create a spiral Christmas type tree using the lathe tool. It specifically shows how to adjust the lathe parameters to get the required shape, and how to properly convert the resulting object into a polygon format. The polygon format will be used to create a subdivision surface object, and will also be UV mapped in the second tutorial.

Smoothly Blending several angular objects

This tutorial shows how to blend several objects together, to make them smoothly connect in order to create one object which can be 3D printed. It specifically shows how to control the blending between objects such that the bridge function can be used to create connecting geometry. This connecting geometry is then formed and molded to create the smoothly blended interconnections.
