OpenCASCADE PCurve of Topological Face eryar@163.com Abstract. OpenCASCADE provides a class BRepBuilderAPI_MakeFace to build topological faces. A face maybe built from a surface, elementary surface from gp package, surface from Geom, from a wire and…

OpenCascade Primitives BRep-Cone eryar@163.com Abstract. BRep is short for Boundary Representation. Boundary Representation gives a complete description of an object by associating topological and geometric information for solid modeling. In this cas…

OpenCASCADE BRep Projection eryar@163.com 一网友发邮件问我下图所示的效果如何在OpenCASCADE中实现,我的想法是先构造出螺旋线,再将螺旋线投影到面上. 为了验证我的想法,结合原来螺旋线的造型算法,来测试下这种效果的实现.依然采用Tcl脚本在Draw Test Harness中试验.个人觉得高效使用OpenCASCADE的方法应该也是先用Tcl脚本来验证一些想法后,再根据使用到的命令找到OpenCASCADE中DRAW的命令实现,最后再可以根据DRA…

OpenCASCADE Ring Type Spring Modeling eryar@163.com 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…

Make Helix Curve in OpenCASCADE eryar@163.com 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…

OpenCASCADE Make Primitives-Sphere eryar@163.com Abstract. The sphere is the simplest topology shape of the BRep structure. But there are several import concept of the sphere edges, such as degenerated edge and seam edge. So construct a sphere by cod…
