waku2005, * Make the intersection line visible in the 3D view by clicking the eye-icon * Open Selection Inspector * Choose the PlotOnIntersectionCurve object from Current Object * Click Create Selection * Choose POINT from Field Type * Click New Value * Enter Composite ID of your interst DataSet from the Data Hierarchy list on the left * Enter 0 in the Index field
And you should be able to see the origin point is highlighted in the 3D view and the 2D plot view. Additionaly, you can see which points in 3D view corresponds to which part of the plot by clicking Select Points On in the menu bar and selecting the points by mouse, with point ID labels if you further do * Click Point Label in the selection inspector * Check Visible * Label Mode: Point IDs.
