1)創建三個點(參見教程5)
2) 將點連成線(參見教程6)
3) 通過三點創建一個參考平面，后面進行圓弧倒角時要用到該平面。
CATIGSMPlane3Points_var Supportplane = spGSMFactory->CreatePlane(spPoint1, spPoint2,spPoint3);
CATISpecObject_var spSupportplane = Supportplane;
4) 創建倒角半徑的參數：
CATICkeParm_var Radius1 = NULL_var;
CATICkeMagnitude_var spRadMag = spParamDictionary->FindMagnitude("LENGTH");
CATUnicodeString name("Radius 1");
Radius1 = spParmFactory->CreateDimension(spRadMag,name, .01);
5) 創建倒角：:
CATIGSMCorner_var Corner1 = spGSMFactory->CreateCorner(spLine1,
spLine2,
spSupportplane,
Radius1,
CATGSMSameOrientation,
CATGSMSameOrientation,
FALSE);
CATISpecObject_var spCorner1 = Corner1;
6) 裁剪去多余的線和點：
CATIGSMSplit_var Split1 = spGSMFactory->CreateSplit(spLine1,
spRadius1,
CATGSMSameOrientation);
CATISpecObject_var spSplit1 = Split1;

CATIGSMSplit_var Split1a = spGSMFactory->CreateSplit(spSplit1,
spRadius3,
CATGSMInvertOrientation);
CATISpecObject_var spSplit1a = Split1a;
7) 將線和圓弧依次連接起來，創建一個序列：
CATLISTV(CATISpecObject_var) joincurves;
joincurves.Append(spSplit1a);
joincurves.Append(spSplit2a);
joincurves.Append(spSplit3a);
joincurves.Append(spRadius1);
joincurves.Append(spRadius2);
joincurves.Append(spRadius3);
8)在講序列連接起來之前，需要創建一個最小的結合距離：
CATICkeParm_var Mergedist = NULL_var;
CATICkeMagnitude_var spMergedist = spParamDictionary->FindMagnitude("LENGTH");
CATUnicodeString mergename("Merge Distance");
Mergedist = spParmFactory->CreateDimension(spMergedist,
mergename,
.0001);
9)連接起來并插入到視圖中：
Now we can join this list of objects into a single shape and insert it into the part.
CATIGSMAssemble_var CurveAssy = spGSMFactory->CreateAssemble(joincurves,
Mergedist,
FALSE);
CATISpecObject_var spCurveAssy = CurveAssy;
