To import curves (hub, shroud, material domain, secondary flow path and volute contour curves):

•File | Import | Points from file

•select *.dat file

•Use "fit curve" to make a spline through desired points

To generate surfaces (blade, volute, diffuser):

•Insert | surface | Through points

•Row degree <= number of blade profile sections

•Column degree <= Row degree-1

•Points from file

•select *.dat file

Please note: If the mentioned menu options are not available, the appropriate commands have to be created:

a)"Tools/Customize" or right click on any toolbar/menu, "Customize..."

b)"Commands", "Insert/Curve/Spline..." or "Insert/Surface/Through Points..."
