Hi Quaritexa, you can use the View > CPlane tool to set the construction plane to be aligned to a surface and then the 2D Top, Front, and Right views will be views relative to that surface instead of their default world axis views.

There is not a built in way to align the 3D view to a surface though. It's possible to do it by a script, would that help? Like something that aligns the 3D view to cplane's z axis so it is looking in the same direction as the Top ortho view?
