Point curves are based on a relatively simple mathematical formula — there are no settings that control the curve's shape. As you place a point curve, it is dynamically displayed as you enter data points. Of course, you can place active points or other elements to snap to as you place the point curve, and you can enter the data points using AccuDraw.

Point curves are placed with the Place Point or Stream Curve tool (Drawing > Home > Placement > Place Multi-line split button).
