Class: McDbBlockTableRecord ​

2d.McDbBlockTableRecord

数据库的块表记录对象，实现了对图块的属性相关操作函数。

Example

// 添加图块
   import { MxCpp, McDbBlockTableRecord, McDbBlockReference, McDbLine, McCmColor } from "mxcad"

   let mxcad = MxCpp.getCurrentMxCAD();
   let blkTable =  mxcad.getDatabase().getBlockTable();
   let blkRecId = blkTable.add(new McDbBlockTableRecord());

   // 根据ObjectId再次得到刚刚添加的图块记录
   let blkTableRecord:McDbBlockTableRecord = blkRecId.getMcDbBlockTableRecord()

   // 添加两条线段再图块记录中 这里每条线段的具体属性比如开始点和结束点自行赋值
   const line = new McDbLine(80, 80, 0, -80, -80, 0)
   line.trueColor = new McCmColor(255, 0, 0)
   const line1 = new McDbLine(-80, 80, 0, 80, -80, 0)
   blkTableRecord.appendAcDbEntity(line);
   blkTableRecord.appendAcDbEntity(line1);

   // 设置图块的基点 一般是包围盒内的点， 可以任意指定
   blkTableRecord.origin = new McGePoint3d(0,0,0);

   // 实例化块参照 这里需要设置我们刚刚添加图块记录得到的ObjectId
   let blkRef = new McDbBlockReference();
   blkRef.blockTableRecordId = blkRecId;
   // 最后设置位置 渲染图块
   blkRef.position = new McGePoint3d(0,0,0);

   mxcad.drawEntity(blkRef);
