This format (*.cftgeo) can be used to import rotational symmetric components only. It is a XML format including the following information:
General information (mandatory) 

Length unit type 
LengthMm for millimeters 
Unshrouded flag 
Only required for vaned designs. 1 = unshrouded, 0 = shrouded 
xTipInlet 
Only required for vaned and unshrouded designs. Tip length at inlet. 
xTipOutlet 
Only required for vaned and unsrhouded designs. Tip length at outlet. 
Meridional contour information (mandatory) 

Hub contour 
Array of curves. At least one curve is required. Each curve contains an array of 2Dpoints (r, z coordinates). 
Shroud contour 
Array of curves. At least one curve is required. Each curve contains an array of 2Dpoints (r, z coordinates). 
Blades information (only required for vaned designs) 

Mean lines and blade thickness data must be provided for both main and splitter blade. Only symmetric blades are supported. 

Span positions 
Relative position between hub and shroud (0...1). Array of at least 2 float numbers. 
Mean line data 
Array of at least 2 curves. Each curve contains an array of 3Dpoints (r, T, z coordinates). 
Thickness data 
Array of 2 curves. The first curve defines thickness data on hub, the second one on shroud. Each curve contains an array of points defined by two coordinates: x = relative point position on mean line Thickness data are required at least for both relative positions, 0 (leading edge) and 1 (trailing edge). The thickness distribution along the mean line is interpolated using all values. 
An example file can be easily generated by exporting any CFturbo component using the "CFturbo Exchange" export interface.
