Normally one places the footprint at the X-Y plane, thus coordinate values of the X axis grow to the right and those of the Y axis towards the back, hence the Z axis shows upwards along the structural levels.
The view from right is then parallel to the Y-Z plane, and the front view is parallel with X-Z plane.
The user can of course freely choose to place the footprint at any other plane. He shall merely observe the orientation of the coordinate system to avoid in advance any mistake or confusion regarding the direction of axes.
Note: Labelling of the axes titles can be modified in application settings .
