现象：开图时 X3dPart 的 EnsureCreated 命中率只有 10.1%，1914 次重建里 721 次产出 NULL（38%），单个对象最多被重建 544 次。 根因：EnsureCreated 的命中条件是 !m_bNeedCreate && m_pSolid != NULL， 而 Rebuild() 里对 Hide 构件是"故意不建几何、直接 return true"—— m_pSolid 按设计就是 NULL，于是每次访问都重新走一遍 Rebuild，永远不可能命中。 子项全为空的构件同理。 修复： - 新增 m_bCreated 标记"已经尝试建过"（无论是否产出实体） - EnsureCreated 命中条件改为 !m_bNeedCreate && (m_bCreated || m_pSolid != NULL) - Rebuild 入口置 m_bCreated = true；所有设 m_bNeedCreate = true 的 setter 同时置 m_bCreated = false，保证参数变化后仍会重建 - 重建后仍无实体时打一条日志（限前 5 条，带 m_sName），方便定位是哪些构件 实测（big1.dwg / R230 Debug）： X3dPart 命中率 10.1% -> 41.4% 重建次数 1914 -> 1248（-666） rebuild_null 721 -> 55 单对象最多重建 544 -> <=3 开图墙钟 93 s -> 93 s（无变化） 注意：这 666 次空转没有带来可测的提速，因为 Rebuild 里 Hide 的早退分支在 布尔运算之前，每次只有几微秒。所以这是正确性/整洁度修复，不是性能修复； 但消除了"个别构件被重试几百次"这种病态行为，也暴露了"哪些构件建不出实体"。 顺带新增诊断（Debug + AEC_PERF_COUNTER=1 才生效，Release 无开销）： - SectionPerf::NoteEnsure()：按 tag 统计"延迟建几何"的命中/重建， 并给出对象维度直方图与重建次数最高的对象 - AecDbX3dPart::Rebuild / AcDbX3dSolid::EnsureCreated / AecDbGuardBar::Draw3d 打点 - tools/run_acad_perf.ps1 增加 -CpuTrace：用 xperf 采 CPU 采样并 merge 成 etl， 可直接喂 tools/perf_diagsession.py（VS 的 VSDiagnostics 在这台机器上会卡住， wpr -stop 有 COM 线程模式 bug，故用 xperf） 验证：R230 Debug 编译通过并部署，自动开图取数；截面缓存与回写仍为 0/正常。

# run_acad_perf.ps1 - automatically open a drawing in AutoCAD, run ENVIPERFDUMP,
|
|
# collect the SectionPerf report, then close only the process we started.
|
|
#
|
|
# Usage (from repo root):
|
|
# powershell -NoProfile -ExecutionPolicy Bypass -File tools\run_acad_perf.ps1
|
|
# powershell ... -Dwg "E:\path\to\big1.dwg" -TimeoutSec 900
|
|
#
|
|
# Notes:
|
|
# - The dump command is executed through a /b script, which AutoCAD runs AFTER the
|
|
# drawing has loaded. The script contains only ENVIPERFDUMP (no QUIT) so that a
|
|
# "save changes?" dialog can never block it; the process is killed by PID instead,
|
|
# so the drawing is never written back.
|
|
# - AEC_PERF_COUNTER=1 is set for the child process only.
|
|
# - Only processes started by this run are terminated: an acad.exe that was already
|
|
# running before launch is left alone.
|
|
# - Must be started from a Debug build that contains the SectionPerf probes
|
|
# (see pipe-section-region-performance-plan.md, Phase 0).
|
|
#
|
|
# Keep this file ASCII-only: Windows PowerShell 5.1 reads BOM-less files as ANSI.
