Class: McDbBlockReference
2d.McDbBlockReference
表示一个 CAD 图块引用实体,一个块参考用于放置、缩放和显示它参考的McDbBlockTableRecord中的一个实体集合的实例
Example
//插入图块
import { McDbBlockReference } from "mxcad"
let mxcad = MxCpp.App.getCurrentMxCAD();
// blkFilePath:图块路径,插入图块
let blkrecId = await mxcad.insertBlock(blkFilePath, "tree");
if (!blkrecId.isValid()) {
// 插入图块
return;
}
// 构造一个新图块引用实体对象
let blkRef = new McDbBlockReference();
// 设置图块记录对象ID
blkRef.blockTableRecordId = blkrecId;
// 得到图块的最小外包
let box = blkRef.getBoundingBox();
if (box.ret) {
let dLen = box.maxPt.distanceTo(box.minPt);
if (dLen > 0.00001) {
blkRef.setScale(mxcad.getMxDrawObject().screenCoordLong2Doc(100) / dLen);
}
}
// 设置图块插入点
let getPoint = new MxCADUiPrPoint();
getPoint.setMessage("\指定插入基点");
// 动态绘制图块
getPoint.setUserDraw((v, worldDraw) => {
blkRef.position = v;
worldDraw.drawMcDbEntity(blkRef);
});
let pt = await getPoint.go();
if (!pt) return;
blkRef.position = pt;// 设置块位置
let newBlkRefId = mxcad.drawEntity(blkRef);// 绘制图块
if (!newBlkRefId.isValid) {
console.log("insert error");
return;
