Custom deck framing and planks

[HemlockC]

Hello,

I am hitting a dead end with custom drawing some deck framing.  I made a multi level deck drawing, with an offset curved end, which I ended up custom drawing joists and beams to make work.  It looks right in framing view, but when planking is applied it still extends past as the rectangle I started with.  I assume I need another step to unify the framing somehow.  Are there more steps to get the planks to relate to the custom made framing as well?  

Thanks for any help, I've searched processes and videos and cant match this exact scenario.  Thanks.

Did you try drawing it with the radius deck railing?
