Class: McDbPolyline

2d.McDbPolyline

McDbPolyline 是多段线实体类，用于创建和管理多段线对象。

Description

该类用于绘制由多段线段组成的复杂图形，支持设置顶点、闭合状态、宽度和显示属性。

使用方法总结：

先创建 McDbPolyline 实例。
再依次添加顶点并设置闭合状态、常量宽度和凸度等样式参数。
最后将其加入当前空间并显示。

Example

import { McDbPolyline, MxCpp } from 'mxcad'
//绘制线宽为10的矩形，pt1,pt2,pt3,pt4为矩形的4点个顶点
const pl = new McDbPolyline();
pl.constantWidth = 10;// 设置多段线线宽为10
// 设置多段线端点
pl.addVertexAt(pt1);
pl.addVertexAt(pt2);
pl.addVertexAt(pt3);
pl.addVertexAt(pt4);
pl.isClosed = true; // 设置多段线是否闭合
MxCpp.getCurrentMxCAD().drawEntity(pl); // 绘制多段线

 // 绘制中心矩形：指定矩形宽高与中心点，动态绘制矩形
 import { McDbPolyline, MxCpp, MxCADUiPrDist, MxCADUiPrPoint } from 'mxcad';

 async function Mx_CenterRect() {
   // 设置矩形宽度
   let width = 5;
   const getWidth = new MxCADUiPrDist();
   getWidth.setMessage("\n请输入矩形宽度<5>");
   const widthVal = await getWidth.go();
   if (widthVal) {
       width = getWidth.value()
   }
   // 设置矩形高度
   let height = 10;
   const getHeight = new MxCADUiPrDist();
   getHeight.setMessage("\n请输入矩形高度<10>");
   const heightVal = await getHeight.go();
   if (heightVal) {
       height = getHeight.value()
   }
   // 设置矩形的中心点
   const getCenterPt = new MxCADUiPrPoint();
   getCenterPt.setMessage("请点击确定矩形中心");
   const centerPt = await getCenterPt.go();
   if (!centerPt) return;
   // 根据矩形的中心点和宽高计算矩形的四个顶点
   let pt1 = new McGePoint3d(centerPt.x + width / 2, centerPt.y + height / 2, centerPt.z)
   let pt2 = new McGePoint3d(centerPt.x - width / 2, centerPt.y + height / 2, centerPt.z)
   let pt3 = new McGePoint3d(centerPt.x - width / 2, centerPt.y - height / 2, centerPt.z)
   let pt4 = new McGePoint3d(centerPt.x + width / 2, centerPt.y - height / 2, centerPt.z)
   let pl = new McDbPolyline;// 构造一个多段线对象
   // 依次添加矩形顶点
   pl.addVertexAt(pt1)
   pl.addVertexAt(pt2)
   pl.addVertexAt(pt3)
   pl.addVertexAt(pt4)
   const mxcad = MxCpp.App.getCurrentMxCAD();
   pl.isClosed = true; // 设置多段线闭合
   mxcad.drawEntity(pl); // 绘制多段线对象
