* Equal length
* Equal length and parallel
* Equal length and perpendicular (say, for ideal targeting of at least one)

In the examples, the general solution for each desired characteristic solution is a cone, each element of which produces one of an infinite number of solution views. When two or more characteristics of, say those listed above, are desired (and for which a solution exists) projecting in the direction of either of the two elements of intersections (one
