Following each section of this course that provides the study parts (inches or mm), there is a section titled Part Discussions. These sections offer discussions and suggestions concerning how to model various parts in the previous section, respectively.

The part numbers in the Part Discussions sections will match part numbers in the Study Parts sections. This makes it easy to locate the Part Discussions for any part of interest.

For some parts, there are complete tutorials explaining how to model them. These consist of step by step descriptions of the process used to model each part. In some cases, multiple methods for modeling the same part will be presented.

For other parts the discussions focus on the different options for modeling them, but don't detail every modeling step. Rather than repeatedly describing the same steps for many parts, this approach emphasizes unique, challenging, or interesting aspects of the part under consideration.

Due to the large number of study parts in this course, there are not entries for every part in the Part Discussions sections. I will add new entries in this section to address questions and comments from students. Therefore, if you have questions or concerns about any part, contact me via the Student Comments system or contact me directly.
