Manually creating a Flat Pattern

Do you think it is possible to create developments manually using solidworks.

Whenever you get stuck trying to extract the development of a part that will not flatten have you ever wondered whether you

could do it manually.

This is the new challenge for all you guys there. How would you extract the geometric information required to create the flat

pattern.

That is when the going gets tough. The tough get going !!!

Any thoughts on how the entire sheetmetal flattening code works !!!!!
