怎样实现拷贝，移动，镜像，偏移，阵列等，但是我不想用acedCommand来调用的命令，用arx怎么实现？

//移动实体
//移动实体
void CTszDwg::MoveEntity(const AcDbObjectIdArray& aryIds,
AcGePoint3d ptStart,
AcGePoint3d ptEnd)
{
AcGeMatrix3d xform1;
xform1.setTranslation(AcGeVector3d(ptEnd-ptStart));
ads_name ssname;
ads_ssadd(NULL,NULL,ssname);
for(int i=0;i谢谢，

AcDbObjectId CLjDwg::GetMirrorEntity(const AcDbObjectId Id,
      AcGePoint3d ptMirAxisStart,
      AcGePoint3d ptMirAxisEnd)
{
AcDbObjectId idMirror=AcDbObjectId::kNull;
AcGeMatrix3d xform1;
//xform1.setToMirroring(AcGeLine3d(ptMirAxisStart,ptMirAxisEnd));
AcGePlane Plan(ptMirAxisStart,AcGePoint3d(ptMirAxisEnd.x,ptMirAxisEnd.y,-100),ptMirAxisEnd);
xform1.setToMirroring(Plan);

AcDbEntity* pEnt=NULL;
acdbOpenObject(pEnt,Id,AcDb::kForRead);
if(pEnt)
{
  AcDbEntity* pEnt0=(AcDbEntity*)pEnt->clone();
  pEnt->close();
  pEnt0->transformBy(xform1);
  idMirror=AddEntity(pEnt0);
  pEnt0->close();
}
return idMirror;
}

void CLjDwg::RotateEntity(const AcDbObjectId Id,
      const AcGePoint3d ptCenter,
      const double dAngle)
{
AcDbObjectId idMirror=AcDbObjectId::kNull;
AcGeMatrix3d xform1;
xform1.setToRotation(dAngle,AcGeVector3d(0,0,1),ptCenter);

AcDbEntity* pEnt=NULL;
acdbOpenObject(pEnt,Id,AcDb::kForWrite);
if(pEnt)
{
  pEnt->transformBy(xform1);
  pEnt->close();
}
}
