Class: McDbLayerTableRecord ​

2d.McDbLayerTableRecord

表示一个图层表记录对象，实现了对图层的属性相关操作函数。

Example

ts
//添加图层
import { McCmColor, MxCpp, McDbLayerTableRecord, McDb } from "mxcad"

const mxcad = MxCpp.getCurrentMxCAD();
// 构造新图层表记录对象
const layer = new McDbLayerTableRecord()
// 设置图层颜色
layer.color = new McCmColor(0, 0, 0)
// 设置图层是否被冻结
layer.isFrozen = true
// 设置图层是否被锁定
layer.isLocked = true
// 设置图层是否被关闭
layer.isOff = true
// 设置图层线宽
layer.lineWeight = McDb.LineWeight.kLnWt018
// 设置图层名
layer.name = "图层名称"
// 获取当前图层表
const layerTable = mxcad.getDatabase().getLayerTable();
// 向图表中添加图层
const objId = layerTable.add(layer)
mxcad.updateDisplay()
