Q3PolyLine_GetData

You can use the Q3PolyLine_GetData function to get the data that defines a polyline and its attributes.

TQ3Status Q3PolyLine_GetData (
TQ3GeometryObject polyLine, 
TQ3PolyLineData *polyLineData);

polyLine

A polyline.

polyLineData

On exit, a pointer to a TQ3PolyLineData structure that contains information about the polyline specified by the polyLine parameter.

DESCRIPTION

The Q3PolyLine_GetData function returns, through the polyLineData parameter, information about the polyline specified by the polyLine parameter. QuickDraw 3D allocates memory for the TQ3PolyLineData structure internally; you must call Q3PolyLine_EmptyData to dispose of that memory.
