Class: MxCADWorldDraw

2d.MxCADWorldDraw

在 AutoCAD 中实现自定义的绘图逻辑，例如绘制图形、标注、符号等。

Example

  import { McDbCustomEntity, McGePoint3d, MxCADWorldDraw, McDbPolyline } from "mxcad";
  // 自定义实体类 继承 McDbCustomEntity
  class McDbTestLineCustomEntity extends McDbCustomEntity {
       // 定义实体内 pt1、pt2 两个点对象
       private pt1: McGePoint3d = new McGePoint3d();
       private pt2: McGePoint3d = new McGePoint3d();
       // 绘制自定义实体
       public worldDraw(draw: MxCADWorldDraw): void {
           // 构造一个新多段线对象pl
           let pl= new McDbPolyline()
           // pl新增点对象
           pl.addVertexAt(this.pt1)
           pl.addVertexAt(this.pt2)
           pl.addVertexAt(new McGePoint3d())
           // 绘制pl多段线
           draw.drawEntity(pl);
       }
  }
