Class: McDbDiametricDimension

2d.McDbDiametricDimension

表示直径标注实体，用于标注圆弧或圆的直径。

Description

McDbDiametricDimension 提供直径尺寸标注能力，通过 chordPoint 和 farChordPoint 定义直径两端点，并支持引线长度与角度参数。它可以生成横穿圆心的直径尺寸标注，适用于圆、圆弧及其他圆形曲线的直径标注。使用方法:

创建 McDbDiametricDimension 实例并设置 chordPoint、farChordPoint 和 leaderLength。
调用 compute()，传入目标实体和拾取点。
将标注对象添加到当前绘图上下文进行显示。

Example

// 绘制直径标注尺寸
import { MxCpp, MxCADResbuf, DxfCode, MxCADUiPrEntity, McDbRadialDimension, MxCADUiPrPoint } from "mxcad";

   async function _DrawDiametricDimension() {
       const mxcad = MxCpp.getCurrentMxCAD()
       const getEnt = new MxCADUiPrEntity();
       getEnt.setFilter(new MxCADResbuf([DxfCode.kEntityType, "ARC,CIRCLE"]));
       getEnt.setMessage(t("选择圆弧或者圆"))
       const entId = await getEnt.go()
       if (entId.isNull()) return;
       const ent = entId.getMcDbEntity();
       if(!ent) return;

       let pick_pt = getEnt.pickPoint();

       let dim = new McDbDiametricDimension();
       dim.dimensionStyle = mxcad.database.getCurrentlyDimStyleId();
       dim.compute(ent,pick_pt);

       let getPoint = new MxCADUiPrPoint();
       getPoint.setUserDraw((currentPoint,pWorldDraw)=>{
           dim.compute(ent,currentPoint);
           pWorldDraw.drawMcDbEntity(dim,true);
       });
       if(!await getPoint.go() ) return;
       mxcad.drawEntity(dim);
   }
