Solid Edge ST7 has added a couple of real breakthrough features in sheet metal. The first one is called Blank Body. The name might need some explanation. This function takes a stamped part and flattens it. The flat shape is the blank. These are parts with geometry you can’t create on a brake press. Solid Edge achieves this with finite element method meshes.
You start with a thin walled part or a solid part where the faces represent the faces of a thin walled part. Solid Edge out puts a flat part with a nominal thickness.
Part of the interface for this feature enables you to set the accuracy on a range from 1 (coarse) to 10 (fine - size reflects the size of the mesh). The accuracy affects the shape and also the solve time. Simple parts like the one shown here will solve in less than 10 seconds on a reasonably recent computer.
Generally this has been the realm of pricy third party software, which is why it’s a bit of a break through to see Solid Edge do this directly. It’s not quite progressive die, which you might need to actually create your parts, but if you can make the part in one hit, this tool may help you simplify your process. If what you really need is a set of progressive dies, that will still be the realm of third party packages. Also it might be a good idea to recreate an existing project where you already know what the blank shape should be so that you can calibrate the precision of the Blank Body tool to your existing process.
The second ST7 Sheet Metal feature that I want to mention here is the Part To Sheet Metal function. This one starts with a solid body, and will thin wall it, rip the corners, add bends, and flatten it. The result is a sheet metal part that can be produced on a brake press. The part shown below is an example of a simple part where this process was used.
Part To Sheet Metal is only available in ordered mode.

The Community will be set to read-only on Sunday, July 20 in preparation for the migration of our GTAC customer forums. The site will still be available for browsing however posting will not be allowed during this time. We anticipate the site will be fully operational on Monday, July 21. Thank you for your patience and cooperation during this time. More information, including an FAQ, on our plans to migrate the BBS to the Siemens PLM Community can be found in the Welcome section of the Community.
