Why do I get a partial export of a board outline from Solidworks to Ciruitworks??

I am using Circuitworks for the first time.  I have a part with a BOARD_OUTLINE sketch defined.  When I open it in Circuitworks, for some reason I only get a partial outline, and for some reason there is also a cutout created where the rest of the board should have been.  Has anyone ever seen anything like this?

(My board outline is "interesting", to say the least.  The part is a flex circuit that has two arms that extend out from the center, they look like squall lines on a hurricane, or the arms on a spiral galaxy, or [my favorite] the arms of a Barrel of Monkeys toy.  Suffice to say that there are several interconnecting splines.)
