The Transformation commands are available by right-clicking the background.
You can use different coordinate systems to display various views of the geometry and mesh objects in the viewer window. This is useful when closely examining every aspect of the mesh before saving it for use in a CFD solver.
The Cartesian coordinate system is used by default in the viewer window when there is only one viewport. The 3 axis coordinates for the Cartesian coordinate system are X, Y and Z.
The blade-to-blade coordinate system is used to display the geometry in the
- 
conformal space, which is familiar to blade designers. The
- 
coordinate space is angle-preserving and minimizes the effect
of changing radius on viewing and manipulation. By utilizing the blade-to-blade
coordinate system, a wide variety of machine types, from axial to radial, can be
treated similarly.
is defined in Meridional.
Note: Due to the fact that 
is ill-conditioned at 
, you can expect to see different behavior in cases for
which the geometry extends to the machine axis.
The meridional coordinate system is one transformation used by blade
designers. It is useful for viewing the flow path as well as the upstream and
downstream extents of the mesh. The three axis coordinates for the meridional
coordinate system are A (axial), R (radial) and 
(Theta). The viewer shows only the A and R coordinates.
