Spiral data - sheet metal help
(OP)
Hey, this is my first post here, so excuse me if this topic has already come up... i didnt find anything in the archives.
So, i have a flat spiral that i am going to cut out of a sheet of 18ga Stainless and i need to know what is going to happen when i 'pull' the center down the axis.... essentially making a spiral layer cake. I know from experience this is going to stretch and twist, but i want to know how much. I tried using the sheet metal tool in SW09 but i had little success.
any help would be great, thanx. matt

Please refer the attached picture. Am I correct?
If so I would like to propose you the following steps:
1) Make a 2D Sketch of the top face of the sheet.
2) Preselect the "Spiral/Helix" feature and click "Convert Entities" command from the Sketch Tools menu to project the spiral into 2D plane.
Now you have the flattened spiral.
3) Create a profile of the cut (you can create a reference plane with "Normal to Curve" option to make a sketch on)
4) Use Swept-Cut feature to make a cut.
