mxcad_2d API 文档 / 2d / MxCppType

Class: MxCppType

2d.MxCppType

MxCppType 是 MxCAD 全局 API 的入口包装类。

Description

该类统一封装了 MxCAD 全局功能，包括底层程序集访问、当前 CAD 对象获取、属性窗口接口、AI 接口、几何对象创建以及字符编码转换。 它让插件开发者可以通过一个统一对象访问 MxCAD 的顶层服务。 使用方法总结：

1. 通过 MxCpp 访问 MxCppType 实例；
2. 使用 App、PropertiesWindow、Ai 等成员获取对应功能入口；
3. 调用 newMcGePoint3d、decodeFromGb2312 等辅助方法完成常见操作。

Example

import { MxCpp } from "mxcad";

const mxcad = MxCpp.getCurrentMxCAD();
const point = MxCpp.newMcGePoint3d({ x: 100, y: 200, z: 0 });
const decoded = MxCpp.decodeFromGb2312("%c4%e3%ba%c3");
console.log(mxcad, point, decoded);
