OpenCascade造型算法——倒圆与倒角. Opencascade Modeling Algorithms Fillets and Chamfers. ModelingAlgorithmsFilletsandChamfers 造型算法——倒圆与倒角 eryar@163.com 一、倒圆FilletConstructor 1.BRepFilletAPI_MakeFillet 使用类BRepFilletAPI_MakeFillet来为形状添加倒圆。倒圆是用光滑面来代替角边。使用方法如下:...
BRepBuilderAPI_MakeWire类 用来创建一个Wire类; 用一个Wire和一个边来生成一个新的Wire: ExistingWire = BRepBuilderAPI_MakeWire(Edge2); Edge3 = BRepBuilderAPI_MakeEdge(gp_Pnt(-300,0,-80),gp_Pnt(-90,20,-30)); BRepBuilderAPI_MakeWire MW1(ExistingWire,Edge3); if (MW1.IsDone()) {Yellow...
OpenCASCADE Chamfer 3D Basics 倒角Chamfer造型功能是几何内核一般都具有的功能,OpenCASCADE中也提供倒角Chamfer造型功能。如下图所示: 在Draw Test Harness中的源文件BRepTest_ChamferCommands.cxx可以看到三维倒角功能的类是BRepFilletAPI_MakeChamfer,通常使用倒角类有两种方式: l 指定要倒角的边Edge及倒角距离:这种情况是...
BRepBuilderAPI_MakeWire mkWire(M1, chamfer, M2);if(mkWire.IsDone()) DBRep::Set(a[1], mkWire.Wire());elseDBRep::Set(a[1], chamfer); }return0; } 从上述源码可以看出,二维曲线倒角功能主要是由类ChFi2d_ChamferAPI实现。OpenCASCADE中的算法类的大致套路就是: ...

OpenCASCADE provides simple API for the construction of primitives, such as box, cone, sphere, cylinder, and torus, .etc. You can make a primitive by a simple class in OpenCASCADE, the sample code as follows: TopoDS_Shape aTopoBox=BRepPrimAPI_MakeBox(3.0,4.0,5.0); ...
现今的CAD 系统大多通常都基于CAD 系统提供的二次开发包,用户根据要求定制符合自己要求的功能。AutoCAD就提供了AutoLISP、ADS 等都是比较通用的开发工具包。UG 也提供了多种二次开发工具:UG/Open MenuScript、UG/Open API 等。然而此类开发有着自身的缺点: ...
(ais3,Standard_False); } BRepFilletAPI_MakeChamfer类创建一个倒角;基类:BRepFilletAPI_LocalOperation;可以设置相关参数,比如倒角两个距离,角度等参数;示例: BRepFilletAPI_MakeChamfer MC(theBox); // add all the edges to chamfer TopTools_IndexedDataMapOfShapeListOfShape M; TopExp::MapShapesAnd...
