I cought a bug that I think may be related to this one:
when using bottom view or front view as direction to create Shape2DView in Draft, the projection will be rotated like attached picture.

Curiously, with the bottom view, the problem only happens when using NaviCube, is View menu is used to set bottom view, the Shape2dView works fine. With front view, the problem happens both when using NaviCube or View menu.
