When you create a flat pattern for a sheet metal part, Inventor seems to rotate or flip the flat in an unwanted way. Is there a way to change the orientation of the flat pattern?
You can do this by right-clicking on the flat pattern node in the browser and choosing Edit Flat Pattern Definition.
As an added note, you can pre-determine the base face (the side facing up) by selecting that face before creating the flat pattern.
If you've defined a simplified punch and center point you can specify that it is shown on the flat pattern as well.
