Hi Karsten,

When you do a blend, the blend factory will fill that in itself, it stores 2 flags for each blend side, a "flipped" flag for whether the side should be flipped from its natural orientation, and a seam parameter for where the seam point should be located on a closed blend.

Those are then stored in the factory input so they will get serialized into history data and a history update will use any customized seam locations that were set by the user inside the Blend command.
