怎样实现拷贝，移动，镜像，偏移，阵列等

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AutoCAD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<aryIds.length();i++)
{
  AcDbObjectId Id=aryIds.at(i);
  ads_name name;
  acdbGetAdsName(name,Id);
  ads_ssadd(name,ssname,ssname);
  ads_ssfree(name);
}
ads_xformss(ssname,xform1.entry);
ads_ssfree(ssname);
}

那怎么样拷贝,偏移?

顶一下

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();
 }
}
