The Render (Properties) > Show Curves command is available by right-clicking an
object (for example, the hub, shroud or blade surface). Use this command to
display curves instead of surfaces. If, in the geometry browser,
Input Mode is set to Profile Points
or Profile Points With Secondary CAD, then the curves
displayed on the blade correspond to the raw curve file data. For other
input modes, the curves represent the underlying CAD surfaces.
For curves displayed on the blade that correspond to the raw curve file data, and for the hub and shroud curves, arrowheads are added to show the direction of increasing point index number. The figures below show curves with arrowheads.
