hello,

[st0426]

I'd like to create DimData (AcDbDimDataPtrArray) in my jig and my custom entity.who can tell me how can l create Dimension in my jig 

//JigEntity
class CMultiCircleJigEntity : public AcDbEntity
{
public:
CMultiCircleJigEntity(const AcGePoint3d & centerPoint, const unsigned int &iNum);
~CMultiCircleJigEntity();
virtual Adesk::Boolean worldDraw (AcGiWorldDraw *mode);
void setRadius(double dRadius);
void appendToCurrentSpace();
private:
AcArray<AcDbCircle *> m_CircArr;
};
CMultiCircleJigEntity::CMultiCircleJigEntity(const AcGePoint3d & centerPoint, const unsigned int &iNum)
{
AcDbCircle *pCirc;
for (int i = 0; i < iNum; i++)
{
pCirc = new AcDbCircle(centerPoint, AcGeVector3d::kZAxis, 1.0);
m_CircArr.append(pCirc);
}
}
CMultiCircleJigEntity::~CMultiCircleJigEntity()
{
for (int i = 0; i < m_CircArr.length(); i++)
{
delete m_CircArr[i];
}
}
Adesk::Boolean CMultiCircleJigEntity::worldDraw(AcGiWorldDraw *mode)
{
for (int i = 0; i < m_CircArr.length(); i++)
{
mode ->geometry().draw(m_CircArr[i]);
}
return (AcDbEntity::worldDraw (mode)) ;
}
inline void CMultiCircleJigEntity::setRadius(double dRadius)
{
if (m_CircArr.length() <= 0)
return;
double dCurRadius = dRadius;
double dRadiusStep = dRadius / m_CircArr.length();

for (int i = 0; i < m_CircArr.length(); i++)
{
m_CircArr[i] ->setRadius(dCurRadius);
dCurRadius -= dRadiusStep;
}
}
void CMultiCircleJigEntity::appendToCurrentSpace()
{
AcDbDatabase * pDb = acdbCurDwg();
AcDbBlockTable * pBlockTable;
pDb ->getBlockTable(pBlockTable, AcDb::kForRead);
AcDbBlockTableRecord *pBlkRec;
if (pDb ->tilemode())
{
pBlockTable ->getAt(ACDB_MODEL_SPACE, pBlkRec, AcDb::kForWrite);
}
else
{
pBlockTable ->getAt(ACDB_PAPER_SPACE, pBlkRec, AcDb::kForWrite);
}
pBlockTable ->close();
for (int i = 0; i < m_CircArr.length(); i++)
{
AcDbCircle *& pCirc = m_CircArr.at(i);
if (Acad::eOk == pBlkRec ->appendAcDbEntity(pCirc))
{
pCirc ->setDatabaseDefaults();
pCirc ->close();
}

{
delete pCirc;
}
}

m_CircArr.removeAll();
