What it does

Autocad Tianzheng Hvac is an agent skill from hashgraph-online/awesome-codex-plugins. Use when controlling AutoCAD 2026 with Tianzheng HVAC T30 through the autocadtianzheng MCP server, including connecting the THvac30V1 profile, reading or creating DWG engineering files, scanning layers/entities/blocks/text into SQLite/JSON/XLSX, running Tianzheng HVAC commands, loading Tianzheng ARX modules, or diagnosing Tangent path issues.

Its SKILL.md is about 760 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

It sits in Documents & Office, covering Excel spreadsheets and MCP servers. It works with Model Context Protocol, SQLite, Microsoft Excel and Python. The repository describes itself as: A curated list of awesome OpenAI Codex / ChatGPT plugins, skills, and resources. The 1 Codex Marketplace. See live plugins at: https://hol.org/plugins/best-codex-plugins. The licence is Apache-2.0.

When your agent uses it

  • Controlling AutoCAD 2026 with Tianzheng HVAC T30 through the autocadtianzheng MCP server
  • Including connecting the THvac30V1 profile
  • Creating DWG engineering files
  • Scanning layers/entities/blocks/text into SQLite/JSON/XLSX

Example prompts

  • “/autocad-tianzheng-hvac”

Requirements

  • Python 3

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. manage_session 连接失败:确认 AutoCAD 2026 路径存在,再看 AutoCAD.Application.25.1 是否可用。不要混用旧版 AutoCAD ProgID。
  2. probe 显示 tangent_root_exists=false 或 ARX 文件不存在:确认 TIANZHENG_ROOT 指向正确的天正暖通安装目录。
  3. CodexAutomation 下没有天正 SupportPath/TRUSTEDPATHS 是预期状态;只有用户手动打开天正 THvac30V1 时才应看到天正路径。
  4. ARX 加载失败:确认文件在 TIANZHENG_ROOT\SYS25x64 下,再用 load_arx 单独加载具体路径。
  5. Codex 看不到 MCP 工具:先确认设置页 "From plugins" 里有 autocad_tianzheng,再重启 Codex,让新环境变量和缓存插件重新加载。

What it can do on your machine

Read from SKILL.md and the folder at commit 3e1456a. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are json).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Autocad Tianzheng Hvac loads about 762 tokens when it runs. Until then it costs about 92 tokens; SKILL.md has 185 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~92
When it runs · the whole SKILL.md, loaded when a task matches
~762

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

AutoCAD 2026 + 天正暖通 HVAC

适用范围

用这个 skill 处理本机 AutoCAD 2026 + 天正暖通 T30V1 的连接、读图、建图、保存、导出和排障。默认 MCP server 是 autocad_tianzheng;在 Codex 设置页的 MCP servers 里,它显示在 "From plugins" 列表下,不一定出现在手动 "Servers" 列表里。

机器相关路径从环境变量读取:

  • AutoCAD: AUTOCAD_EXE,例如 <AutoCAD 2026 install>\acad.exe
  • 天正暖通根目录: TIANZHENG_ROOT,例如 <Tangent THvacT30V1 root>
  • 天正 profile: THvac30V1
  • COM 自动化 profile: CodexAutomation
  • AutoCAD 2026 COM ProgID: AutoCAD.Application.25.1
  • MCP 工程: AUTOCAD_TIANZHENG_MCP_ROOT,指向本机 multiCAD-mcp 工作树
  • Python 解释器: AUTOCAD_TIANZHENG_PYTHON,可选;未设置时使用当前环境里的 python
  • 默认输出: 优先放在 MCP 工程外的用户指定工作目录;不要写入插件仓库

标准连接流程

  1. 先连接指定 CAD 类型,不要依赖自动探测。稳定自动化模式通过 CodexAutomation 启动干净 AutoCAD 2026;如果用户已手动打开天正,则可只附加当前运行会话。
json
[{"action":"connect","cad_type":"tianzheng_hvac"}]

把上面的 JSON 字符串传给 manage_session。

  1. 连接后立刻探测天正状态:
json
[{"action":"probe"}]

把上面的 JSON 字符串传给 manage_tianzheng。重点看 current_profile、tangent_root_exists、missing_paths、support_path、trusted_paths 和三个 ARX 文件是否存在。

常见正常状态:

  • 用户手动打开天正时,current_profile 通常是 THvac30V1
  • Codex 自动化冷启动时,current_profile 通常是 CodexAutomation
  1. 做天正命令前再显式加载暖通 ARX:
json
[{"action":"load_arx"}]

默认加载 Tch_HvacCmd.arx、Tch_PipeBase.arx、tch_pipewire.arx。不要把 auto_load_arx 改成默认开启;历史上自动加载天正核心 ARX 可能触发 AutoCAD 崩溃。

读图与索引

读取工程图时先用普通 CAD 工具查询图层、块、实体,再用天正索引补充可检索数据。扫描 ModelSpace 到 SQLite:

json
[{
  "action":"scan_index",
  "db_path":"<output-root>\\index\\autocad_tianzheng_index.sqlite",
  "json_path":"<output-root>\\index\\autocad_tianzheng_index.json",
  "xlsx_path":"<output-root>\\index\\autocad_tianzheng_index.xlsx"
}]

索引内容包括图纸路径、实体 handle、对象类型、图层、颜色、线型、文字、块名/名称、坐标 JSON。需要追溯对象时优先用 handle。

建图与保存

新建图纸先调用 manage_files 的 new,再用 draw_entities 画基础实体和文字。保存用绝对路径:

text
save|<output-root>\drawings\smoke_autocad_tianzheng.dwg

复杂工程文件优先分层创建:轴网/墙体/风管/水管/设备/标注/文字分别放到清晰图层;块名、图层名、文字标注要可检索。不要在没有用户确认的情况下覆盖已有 DWG。

执行天正命令

通过 manage_tianzheng 的 run_command 执行低风险命令:

json
[{"action":"run_command","command":"_ABOUT","timeout_sec":10}]

如果返回 Command is still active or waiting for user input,说明命令大概率需要人工点选、输入或对话框确认。不要继续盲目发送回车或坐标,先报告需要人工交互。

排障顺序

  1. manage_session 连接失败:确认 AutoCAD 2026 路径存在,再看 AutoCAD.Application.25.1 是否可用。不要混用旧版 AutoCAD ProgID。
  2. probe 显示 tangent_root_exists=false 或 ARX 文件不存在:确认 TIANZHENG_ROOT 指向正确的天正暖通安装目录。
  3. CodexAutomation 下没有天正 SupportPath/TRUSTEDPATHS 是预期状态;只有用户手动打开天正 THvac30V1 时才应看到天正路径。
  4. ARX 加载失败:确认文件在 TIANZHENG_ROOT\SYS25x64 下,再用 load_arx 单独加载具体路径。
  5. Codex 看不到 MCP 工具:先确认设置页 "From plugins" 里有 autocad_tianzheng,再重启 Codex,让新环境变量和缓存插件重新加载。
