  • 新增 m_bNeedCreate 标志与 EnsureCreated()：dwgInFields 与拷贝构造
    不再立即 ReCreate，延迟到首次访问几何时重建
  • 开图时不再对每个单元逐个走 SAT 临时文件（acisOut/acisIn），
    显著降低开图耗时；Clone 也省掉一次重建
  • 所有读取 m_pSolid/m_pSubDMesh 的入口统一走 EnsureCreated：
    GetNative3dSolid / GetDraw3dSolid / GetNativeSubDMesh /
    GetDrawSubDMesh / GetDrawSubDMesh2D / GetCentoridPoint
  • GetDrawSubDMesh 补 m_pSubDMesh 空指针保护
  • TransformBy 保持原有行为（参数变更后必须重建）
