This lineArray certainly belongs to some Shape3D, let's call it shape, for the sake of
example. Suppose also that your point is called point. Do:
Transform3D t = new Transform3D();
shape.getLocalToVworld(t); // shape is the Shape3D to which your linearray belongs
t.invert();
t.transform(point); // "point" first contained your point in world coordinates and
after this call will contain local lineArray coordinates

Try this :
Transform3D t = new Transform3D();
shape.getLocalToVworld(t);
t.transform(point); // "point" first contained your point local coordinates, and now
will have world coordinates

Hope this helps
