Closed tubular plates are not manufacturable. The tube must be split by at least two axial seams. (Molded Form)
Object Type in the To Do List: Tubular plate system.
Meaning: A root plate system can be defined as a tube but a single plate part cannot be manufactured in the shape of a tube. At least two axial seams must split the plate system.
Recovery: Verify that the seams exist. If they do not, split the plate with a minimum of two seams that are along the longitudinal axis of the plate.
Seams in close proximity can cause trim errors on the plate parts. Adjust the seams if necessary.
