示例 2:绘制管路法兰盘

运行示例脚本:

python examples/03_draw_flange.py

自动生成外径 165mm、内孔 50mm、PCD 125mm 均布 4×Φ18 螺栓孔的法兰盘正投影与剖面侧视图。

示例 3:电气工程零部件——图块与复用训练 (A3全图)

运行示例脚本:

python examples/04_exp2_electrical_parts.py

一键生成标准 A3 横向图幅下的 4 个电气设备机加工零件(电机转轴、端盖法兰盘、接线盒安装板、电机散热风扇轮毂),自动封装 TITLE_BLOCK_A3 参数化属性标题栏、MOTOR_END_COVER 与 TERMINAL_PLATE 具名工程图块,并导出独立图块库与 4K 超清光栅预览。

示例 4:自然语言直接驱动

在支持 MCP 的 AI 聊天窗口中直接输入:

“帮我在 CAXA 里绘制一个法兰盘:外径 120mm,内径 40mm,厚度 15mm,在 85mm 分度圆上均布 4 个 12mm 螺栓孔,带尺寸标注,使用 A3 国标图纸。”

AI 将自动调用 caxa_draw_parametric_part 工具,2 秒内即可在您的 CAXA 屏幕上完成出图!
