Choose as Few Points as Possible for Each Path Segment

In this example the advice has been taken too literally!

A point has been chosen on the shoulder, and another on the abdomen, but the path between then fails to clear the bulge of the upper chest.

If this was fitted part of the belt would get stuck "inside" the chest shells.

The problem could be solved in two ways: either by increasing the initial distance by which the belt is projected outwards prior to fitting (which would be an inefficient solution), or by adding an extra point.

Here the problem has been solved by adding an extra point on the upper chest to force the belt path clear of the dummy.

(This is more efficient than increasing the projection distance since fewer form-finding iterations will be required to pull the path back into contact with the dummy.)

However the principle of using as few points as possible to define the belt path is correct as it will give a simpler and smoother path, as well as reducing the likelihood of reverse curvature. (As with approximating functions with polynomials, a lower order equation will give a smoother, if less precise, fit.)

Remember that the initial path does not have to adhere exactly to the dummy's contours: a simpler and looser shape will work just as well as it will be pulled back onto the dummy surface by the form-finding process.
