Sheetmetal TC Survey - Flat Pattern vs. Flat State

In our recent Sheetmetal Technical Committee meeting we had a discussion on the functionality and usage of Flat Pattern versus Flat State, and which of the two is used more by users.

If you create a flat model with your Sheetmetal parts, which functionality do you utilize, the Flat Pattern or Flat State?

Why?

Is this a personal preference or company standard/practice?

What do you use these flat models for?
For example:
Just for verification that a model unfolds?
Send the flat model to a vendor/in house shop?
Create a flat model drawing?

Do you (your company) create Flat Pattern (State) drawings?

If yes, is the drawing partially or fully dimensioned?
Is this done for every Sheetmetal part, or specific circumstances that drive this?
What dimension scheme do you use for flat drawings, linear or ordinate?

Thank you for your time and feedback

I don't use the flat pattern or flat state functionality. I frequently need multiple bend states so create my own family table with several instances. One of these is a flat pattern but I like full control over everything & keeping everything as straight forward and basic as possible. Thus I almost never use semi automated tools like flat pattern. I find they get in the way more than they help.

There are a lot of Pro/E features that are on my banned list, things like shaft, flange & neck can all be done with more flexible basic commands like revolve, etc.
