Jun 14, 2015 at 19:13	history	edited	Manfred Weis	CC BY-SA 3.0	provided a new definition of the curves which indicates that the curves need not be planar

Jun 14, 2015 at 8:12	comment	added	Manfred Weis		@Houtarou you are right, that would demand a conincing proof; currently it only seems reaonable. I will try to come with a plausible argument.
Jun 14, 2015 at 5:00	comment	added	Gheehyun Nahm		Why do you think that both curves must be planar?
Jun 14, 2015 at 4:59	comment	added	Gheehyun Nahm		I think that the second condition does not have to be satisfied. For instance, if there is a infinite line, and a circle around that line, the condition holds.
Jun 11, 2015 at 7:18	history	edited	Manfred Weis	CC BY-SA 3.0	formulated conditions for the curves
Jun 9, 2015 at 12:51	history	edited	Manfred Weis	CC BY-SA 3.0	added the example of an oloid as a convex hull of two space curves that is the union of line-segents
