Convert BSpline Curve to Arc Spline in OpenCASCADE eryar@163.com Abstract. The paper based on OpenCASCADE algorithms to approximate the NURBS curve to arc spline. The method is most useful in numerical control to drive the cutter along straight line…

OpenCASCADE Shape Location eryar@163.com Abstract. The TopLoc package of OpenCASCADE gives resources to handle 3D local coordinate systems called Locations. A Location is a composition of elementary coordinate systems, each one is called a Datum. The…

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…
