Steve, When you were saving your trace out, what version of ParaView were you using? I just tried today's CVS and I do indeed get a correct trace for the PlotOverLine as under:
.... PlotOverLine1 = PlotOverLine( Source="High Resolution Line Source" ) PlotOverLine1.Source.Point1 = [-10.0, -10.0, -10.0] PlotOverLine1.Source.Point2 = [10.0, 10.0, 10.0] ....
