In this study, we define a new type of associated curves in the Euclidean 3-space such
as normal-direction curve and normal-donor curve. We obtain characterizations for these curves.
Moreover, we give applications of normal-direction curves to some special curves such as helix,
slant helix, plane curve or normal-direction (ND)-normal curves in E
3
. And, we show that slant
helices and rectifying curves can be constructed by using normal-direction curves.
