本文介绍了如何创建以下类型的尺寸标注元素：角度、弧长、半径、直径、对齐和线性。

角度尺寸标注

要创建角度尺寸标注，请使用 OdBmAngularDim 类的对象，然后调用 set() 函数设置必要的参数。例如：


static void createAngularDimension(OdBmDatabase* pDb, OdBmUserIO* pIO)
{
  OdGePoint3d ptCenterDefault(22.1240720089099, 2.90405468534166, 0.0);
  OdGePoint3d ptCenter = pIO->getPoint("Enter center point: ", OdEd::kInpDefault, &ptCenterDefault);
  double fRadius = pIO->getReal("Enter radius:", OdEd::kInpDefault, 4.08137512304016);
  OdInt32 iViewHandle = pIO->getInt("Enter view id: ", OdEd::kInpDefault, 1839);
  OdInt32 iCurve1Handle = pIO->getInt("Enter first reference id: ", OdEd::kInpDefault, 2759);
  OdInt32 iCurve2Handle = pIO->getInt("Enter second reference id: ", OdEd::kInpDefault, 2870);
   OdBmGArcPtr pGArc = OdBmGArc::createObject();
  OdGeVector3d vecX = OdGeVector3d::kXAxis, vecY = OdGeVector3d::kYAxis;
  OdResult res = pGArc->set(ptCenter, vecX, vecY, fRadius, 0.0, Oda2PI);
  if (eOk != res)
  {
    pIO->putError(OD_T("Arc creation error"));
    return;
  }
   OdBmAngularDimPtr pAngDim = OdBmAngularDim::createObject();
  OdBmObjectId angDimId = pDb->addElement(pAngDim);
   OdBmObjectId viewId = pDb->getObjectId(OdDbHandle(iViewHandle));
  if (viewId.isNull())
  {
    pIO->putError(OD_T("View id is null"));
    return;
  }
   OdBmDBViewPtr pView = pDb->getObjectId(OdDbHandle(iViewHandle)).safeOpenObject();
  if (pView.isNull())
  {
    pIO->putError(OD_T("View open error"));
    return;
  }
   OdBmObjectId curveElemId1 = pDb->getObjectId(OdDbHandle(iCurve1Handle));
  if (curveElemId1.isNull())
  {
    pIO->putError(OD_T("First reference is null"));
    return;
  }
   OdBmObjectId curveElemId2 = pDb->getObjectId(OdDbHandle(iCurve2Handle));
  if (curveElemId2.isNull())
  {
    pIO->putError(OD_T("Second reference is null"));
    return;
  }
   OdBmGeomRefPtr pGeomRef1 = OdBmGeomRef::createObject();
  pGeomRef1->set(curveElemId1);
  OdBmGeomRefPtr pGeomRef2 = OdBmGeomRef::createObject();
  pGeomRef2->set(curveElemId2);
   res = pAngDim->set(pView, pGArc, pGeomRef1, pGeomRef2);
  if (eOk != res)
  {
    pIO->putError(OD_T("Angular dimension set error"));
    return;
  }
   pIO->putString(OD_T("Angular dimension successfully created"));
  }

弧长尺寸标注

要创建弧长尺寸标注，请使用 OdBmArcLengthDim 类的对象，然后调用 set() 函数设置必要的参数。例如：


static void createArcLengthDimension(OdBmDatabase* pDb, OdBmUserIO* pIO)
{
  OdGePoint3d ptCenterDefault(17.7604422726176, 14.1449565742308, 0.0);
  OdGePoint3d ptCenter = pIO->getPoint("Enter center point: ", OdEd::kInpDefault, &ptCenterDefault);
  double fRadius = pIO->getReal("Enter radius:", OdEd::kInpDefault, 6.96388715532212);
  OdInt32 iViewHandle = pIO->getInt("Enter view id: ", OdEd::kInpDefault, 1839);
  OdInt32 iCurveHandle = pIO->getInt("Enter reference id: ", OdEd::kInpDefault, 3499);
   OdBmGArcPtr pGArc = OdBmGArc::createObject();
  OdGeVector3d vecX = OdGeVector3d::kXAxis, vecY = OdGeVector3d::kYAxis;
  OdResult res = pGArc->set(ptCenter, vecX, vecY, fRadius, 0.0, Oda2PI);
  if (eOk != res)
  {
    pIO->putError(OD_T("Arc creation error"));
    return;
  }
   OdBmArcLengthDimPtr pArcLengthDim = OdBmArcLengthDim::createObject();
  OdBmObjectId arcLengthDimId = pDb->addElement(pArcLengthDim);
   OdBmObjectId viewId = pDb->getObjectId(OdDbHandle(iViewHandle));
  if (viewId.isNull())
  {
    pIO->putError(OD_T("View id is null"));
    return;
  }
   OdBmDBViewPtr pView = pDb->getObjectId(OdDbHandle(iViewHandle)).safeOpenObject();
  if (pView.isNull())
  {
    pIO->putError(OD_T("View open error"));
    return;
  }
   OdBmObjectId curveElemId = pDb->getObjectId(OdDbHandle(iCurveHandle));
  if (curveElemId.isNull())
  {
    pIO->putError(OD_T("Reference is null"));
    return;
  }
   OdBmGeomRefPtr pGeomCurveRef = OdBmGeomRef::createObject();
  pGeomCurveRef->set(curveElemId);
  OdBmGeomRefPtr pGeomRef1 = OdBmGeomRef::createObject();
  pGeomRef1->set(curveElemId, 0L, 1L);
  OdBmGeomRefPtr pGeomRef2 = OdBmGeomRef::createObject();
  pGeomRef2->set(curveElemId, 0L, 0L);
   res = pArcLengthDim->set(pView, pGArc, pGeomCurveRef, pGeomRef1, pGeomRef2);
  if (eOk != res)
  {
    pIO->putError(OD_T("ArcLength dimension set error"));
    return;
  }
   pIO->putString(OD_T("ArcLength dimension successfully created"));
}

半径尺寸标注

要创建径向尺寸，请使用 OdBmRadialDim 类的一个对象，然后调用 setRadialDimension() 函数来设置必要的参数。例如：


static void createRadialDimension(OdBmDatabase* pDb, OdBmUserIO* pIO) 
{
  OdGePoint3d ptCenterDefault(-5.27049660828928, 12.3608082899518, 0.0);
  OdGePoint3d ptCenter = pIO->getPoint("Enter center point: ", OdEd::kInpDefault, &ptCenterDefault);
  OdInt32 iViewHandle = pIO->getInt("Enter view id: ", OdEd::kInpDefault, 1839);
  OdInt32 iCurveHandle = pIO->getInt("Enter reference id: ", OdEd::kInpDefault, 3334);
   OdBmRadialDimPtr pRadialDim = OdBmRadialDim::createObject();
  OdBmObjectId radialDimId = pDb->addElement(pRadialDim);
   OdBmObjectId viewId = pDb->getObjectId(OdDbHandle(iViewHandle));
  if (viewId.isNull())
  {
    pIO->putError(OD_T("View id is null"));
    return;
  }
   OdBmDBViewPtr pView = pDb->getObjectId(OdDbHandle(iViewHandle)).safeOpenObject();
  if (pView.isNull())
  {
    pIO->putError(OD_T("View open error"));
    return;
  }
   OdBmObjectId curveElemId = pDb->getObjectId(OdDbHandle(iCurveHandle));
  if (curveElemId.isNull())
  {
    pIO->putError(OD_T("Reference is null"));
    return;
  }
   OdBmGeomRefPtr pGeomCurveRef = OdBmGeomRef::createObject();
  pGeomCurveRef->set(curveElemId);
   OdResult res = pRadialDim->setRadialDimension(pView, pGeomCurveRef, ptCenter);
  if (eOk != res)
  {
    pIO->putError(OD_T("Radial dimension set error"));
    return;
  }
   pIO->putString(OD_T("Radial dimension successfully created"));
}

直径尺寸

要创建直径尺寸，请使用 OdBmRadialDi 类的一个对象，然后调用 setDiameterDimension() 函数来设置必要的参数。例如：


static void createDiameterDimension(OdBmDatabase* pDb, OdBmUserIO* pIO) 
{
  OdGePoint3d ptCenterDefault(4.49545743186403, 10.2000307739949, 0.0);
  OdGePoint3d ptCenter = pIO->getPoint("Enter center point: ", OdEd::kInpDefault, &ptCenterDefault);
  OdInt32 iViewHandle = pIO->getInt("Enter view id: ", OdEd::kInpDefault, 1839);
  OdInt32 iCurveHandle = pIO->getInt("Enter reference id: ", OdEd::kInpDefault, 2706);
   OdBmRadialDimPtr pRadialDim = OdBmRadialDim::createObject();
  OdBmObjectId radialDimId = pDb->addElement(pRadialDim);
   OdBmObjectId viewId = pDb->getObjectId(OdDbHandle(iViewHandle));
  if (viewId.isNull())
  {
    pIO->putError(OD_T("View id is null"));
    return;
  }
   OdBmDBViewPtr pView = pDb->getObjectId(OdDbHandle(iViewHandle)).safeOpenObject();
  if (pView.isNull())
  {
    pIO->putError(OD_T("View open error"));
    return;
  }
   OdBmObjectId curveElemId = pDb->getObjectId(OdDbHandle(iCurveHandle));
  if (curveElemId.isNull())
  {
    pIO->putError(OD_T("Reference is null"));
    return;
  }
   OdBmGeomRefPtr pGeomCurveRef = OdBmGeomRef::createObject();
  pGeomCurveRef->set(curveElemId);
   OdResult res = pRadialDim->setDiameterDimension(pView, pGeomCurveRef, ptCenter);
  if (eOk != res)
  {
    pIO->putError(OD_T("Diameter dimension set error"));
    return;
  }
   pIO->putString(OD_T("Diameter dimension successfully created"));
}

线性与对齐尺寸

要创建线性标注，请使用 OdBmLinearDimString 类的对象，然后调用 set() 函数来设置必要的参数。例如：


static void createLinearDimension(OdBmDatabase* pDb, OdBmUserIO* pIO)
{
  OdGePoint3d ptStartDefault(-8.645793834855073, -7.795546120725747, 0.0);
  OdGePoint3d ptEndDefault(10.899522456510667, -7.795546120725747, 0.0);
  OdGePoint3d ptStart = pIO->getPoint("Enter start point: ", OdEd::kInpDefault, &ptStartDefault);
  OdGePoint3d ptEnd = pIO->getPoint("Enter end point: ", OdEd::kInpDefault, &ptEndDefault);
  OdInt32 iViewHandle = pIO->getInt("Enter view id: ", OdEd::kInpDefault, 1839);
   OdBmGLinePtr pGLine = OdBmGLine::createObject();
  OdResult res = pGLine->set(ptStart, ptEnd);
  if (eOk != res)
  {
    pIO->putError(OD_T("Line creation error"));
    return;
  }
   OdBmLinearDimStringPtr pLinearDimString = OdBmLinearDimString::createObject();
  OdBmObjectId linearDimId = pDb->addElement(pLinearDimString);
   OdBmObjectId viewId = pDb->getObjectId(OdDbHandle(iViewHandle));
  if (viewId.isNull())
  {
    pIO->putError(OD_T("View id is null"));
    return;
  }
   OdBmDBViewPtr pView = pDb->getObjectId(OdDbHandle(iViewHandle)).safeOpenObject();
  if (pView.isNull())
  {
    pIO->putError(OD_T("View open error"));
    return;
  }
   OdInt32 numRefs = pIO->getInt("Enter number of references:", OdEd::kInpDefault, 3);
  OdBmGeomRefPtrArray arrGeomRefs; // 3580, 3957, 4054
  for (OdUInt32 i = 0; i < numRefs; i++) 
  {
    OdInt32 iCurveHandle = pIO->getInt("Enter reference id: ", OdEd::kInpDefault);
    OdBmObjectId curveElemId = pDb->getObjectId(OdDbHandle(iCurveHandle));
    if (curveElemId.isNull())
    {
      pIO->putError(OD_T("Reference is null"));
      return;
    }
    OdBmGeomRefPtr pGeomRef = OdBmGeomRef::createObject();
    pGeomRef->set(curveElemId);
    arrGeomRefs.append(pGeomRef);
  }
   res = pLinearDimString->set(pView, pGLine, arrGeomRefs);
  if (eOk != res)
  {
    pIO->putError(OD_T("Linear dimension set error"));
    return;
  }
   pIO->putString(OD_T("Linear dimension successfully created"));
}
