     摘要: Abstract. OpenCASCADE does not provide helix curve directly, but you can build a helix curve by the pcurve of a surface(curve on surface). When you understand the pcurve of a surface, you can make a helix curve easily. The paper first make a helix by Tcl in Draw Test Harness, then translate the Tcl script to OpenCASCADE C++ code.
