Abstract. The general method to directly create an edge is to give a 3D curve as the support(geometric domain) of the edge. The curve maybe defined as a 2D curve in the parametric space of a surface: PCurve. When you understand the pcurve, you can modeling some interesting shapes, such as bottle neck thread, helix spring, ring type spring. Etc. The paper is focus on the Ring Type Spring Modeling in OpenCASCADE Draw Test Harness by Tcl script.
