The patch worked, also. Using the patch instead of sewing solids, I didn't have to create extra surfaces (to enclose the second set of sheets), which means it regenerates quicker. Thanks!
Does anyone know if there's a way to contribute sheets to an existing solid (to make a new, bigger solid)? I've already created a sewn feature and want to add some more bulk to it. I've tried creating two sewn features and uniting them, but this seems to require quite a bit of computational...
Does anyone have suggestions about how to dimension/constrain sketches such that the alternate solution is avoided? Specifically, do you have experiences that suggest a certain minimum dimension is required to avoid flipping, or does it help to have reference curves "holding things...
