Coordinate systemThe tree dimensional construction is being modelled (input) within a
Cartesian
coordinate system. Normally one places the footprint at the XY 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 YZ plane, and the front view is parallel with XZ 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 . See also: Projec types, Element Editor, Elements 2D window, Elements 3D window, Elements 23 window
