' NX Journal: 冒烟测试母模创建 (按需生成服务联调用, 2026-08-26; NX 2506 实测修正版)
'
' ▍干什么: 打开"当前工作目录\KC_master.prt"(启动前由脚本从 NX 模板复制) →
'   建 bore/stroke/magOn/mountIdx 四个表达式 (UF 底层 API, 跨版本稳定) → 建方块实体 → 保存
'   用途: 验证 worker_journal.vb 全链路 (打开→设表达式→更新→导出 4 格式) 在无真实母模时跑通。
'   真母模建好后同名替换 catalog-masters\KC\KC_master.prt, 本脚本可弃。
'
' ▍运行 (run_journal 只接受一个参数, 用 WorkingDirectory 定位):
'   WorkingDirectory = catalog-masters\KC
'   run_journal.exe <本文件完整路径>
