Dynamic Block line to adapt to rotating contour

[i_try]

I have a dynamic block for section cuts and I need the interior line to adapt stretch to to be trimed by the contour when I turn it.

 

this is the block when I select it for the time being. My current work around is that I have the line constrained with a stretch that I manually need to bring to the edge.

 

 

 

I also have a visibility state so I can pass from section with page or same page is there a way to place the same attribute (Not two as I currently have) in two location depending on the state?

Is there someone who knows how to make this work?

with just the flip and the turn.

I also have a visibility state so I can pass from section with page or same page is there a way to place the same attribute in two location depending on the state?

 

thanks
