Yep, In agreement with Hombre.
A nuc is basically the same layout as a full hive - just that two sides are reduced in length to suit the number of frames needed. Fairly simple, basic and not hard to calculate the new measurements required. Roof, floor, crownboard and frame runners have to fit the box, of course. Apart from that, nothing much different.
Just note that the standard nucs are generally sized to fit two on a full brood box. Following carefully, a set of plans without knowing why they have certain features, is just for the unthinking among us and will not further one's education a great deal.
If you would like a real example to study and compare, look at the old sectional plans for sash windows and those of the cheaper modern versions. You should realise why those craftsmen made them that way in earlier days when sash windows were the bees' knees.
