The Capped check box on the Round tab caps (closes) only the gaps of the active transition, while the Create end surfaces check box located on the Options tab caps all round piece ends for the entire round feature. The Round tab check box overrides the Options tab check box. This enables you to cap the gaps of the active transition even if you decide not to cap all of the round piece ends for the round feature.

This check box is available only if you select a transition type (other than Default) and use the Surface or New quilt attachment type.

You cannot cap rounds between a solid surface and a quilt surface.
