Q3Line_GetData
You can use the Q3Line_GetData function to get the data that defines a line and its attributes.
TQ3Status Q3Line_GetData (
TQ3GeometryObject line, 
TQ3LineData *lineData);
line
A line.
lineData
On exit, a pointer to a TQ3LineData structure that contains information about the line specified by the line parameter.

DESCRIPTION
The Q3Line_GetData function returns, through the lineData parameter, information about the line specified by the line parameter. QuickDraw 3D allocates memory for the TQ3LineData structure internally; you must call Q3Line_EmptyData to dispose of that memory.
