1)創(chuàng)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(chuàng)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(chuàng)建倒角半徑的參數(shù)：

CATICkeParm_var Radius1 = NULL_var;

CATICkeMagnitude_var spRadMag = spParamDictionary->FindMagnitude("LENGTH");

CATUnicodeString name("Radius 1");

Radius1 = spParmFactory->CreateDimension(spRadMag,name, .01);

5) 創(chuàng)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(chuàng)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(chuàng)建一個最小的結(jié)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;

spCurveAssy->Update();

CATIGSMProceduralView_var spCurObj = Curveassembly;

spCurObj->InsertInProceduralView();
