I guess I still don’t fully get your problem. Maybe it’s a language problem. So sorry, if you already know.
In Model views, you can draw whatever 3D object you want and orient any view to whatever plane (CPlane, World plane, planar surface) you want.
Orienting a View to a CPlane will do so according to the CPlanes axes. If you are not satisfied with the orientation, you can either create the CPlane so the axes are rotated or you can rotate the view around the cameras view axis. (CTRL+Shift+PgUp/PgDwn or CTRL+Shift+RMB)
Any detail in Layout mode is just another View, you can orient as you wish. You need to double click a detail to activate it. An activated detail looks and behaves like any model view.
You should not use Layout mode to draw anything other that 2D. Layout mode is meant to place (2d) detail views (of 3D models), annotate and maybe add some 2D line work.
