Abstract: Abstract The tangent developable of a curve C ⊂ ℙ3 is a singular surface with a cuspidal edge along C and the flex tangents of C. It also contains a multiple curve, typically double, and we express the degree of this curve in terms of the invariants of C. In many cases we can calculate the intersections of C with the multiple curve, and pictures of these cases are provided.
