This tip comes from one of our clients in the Cleveland area (thanks go to Mark Gross). The Accel Group repeatidly does a wrap of thin material around their designs to the point where there is really no deformation in the design. Think a laminate wrap on a curved desk or countertop. In order to facilitate their design and production drawings they needed something to flatten from a curve without deforming. Immediately the Bend Part command is out, they don't want to use iParts, so lets use Sheet Metal!
Traditional Sheet Metal deformations use a value, equation, or bend table to control the deformation of material. The most common being the value of K-Factor which states a linear axis for material deformation on a part.
So in order to flatten their wood/laminate to not deflect we need to change the K-Factor in Inventor to a value of 1 so no compression or tension will be created on the part. In your sheet metal parts consider adding a new k-Factor for this type of situation.
One thing you will have to watch though is which direction you create your features so the k-Factor works correctly with your geometry. If you go the opposite way of your geometry you might need to change your k-Factor to 0 instead. Just watch what you are doing.
