how to control layer in detailed view

Hi DS community,

I drawn a building in model space  
on layer "Architectonics" there are only the frames of the wall
another one is with the bricks between the wall limits.

I want to have a Viewport with only the frames,
another viewport with frame and bricks.

Acting alternatively in each viewports i uncheck/check "show" for the brick layer.
But i never succeed or i get bricks in the two views either no brick at all.

Where am i wrong ?

Thanks in advance
