MxCADUtilityClass 类提供了一系列与绘图相关的工具方法。

Example

import { MxCADUtility, MxCADUiPrPoint } from "mxcad"
//点选
 const getPoint = new MxCADUiPrPoint()
   const point = await getPoint.go()
   if(!point) return
   let objId = MxCADUtility.findEntAtPoint(point.x, point.y,point.z,-1,filter)
   // 选中对象设置高亮
   MxCADUtility.highlightEntity(objId.id, true)
   console.log(objId)
