Class: McDbProxyEntity
2d.McDbProxyEntity
代理实体类型,是一种特殊类型的实体,其几何形状和属性信息存储在外部源中,例如外部文件或数据库。
Example
//遍历代理实体中的文字
import { MxCADSelectionSet, McDbProxyEntity } from "mxcad";
let ss = new MxCADSelectionSet();// 构造选择集对象
// 设置过滤器
let filter = new MxCADResbuf();
filter.AddMcDbEntityTypes("TEXT,MTEXT,INSERT,ACAD_PROXY_ENTITY");
ss.allSelect(filter);// 筛选图纸上所有的文本、图块、代理实体对象
// 遍历选择对象
ss.forEach((id,item)=>{
const ent = id.getMcDbEntity();
if(ent instanceof McDbProxyEntity){
let proxyEntity: McDbProxyEntity = ent;
let aryText = proxyEntity.getAllTextContent();
aryText.forEach((val)=>{
console.log("遍历文字", val);
});
})

syncData
▸ syncData(_toCpp?
): boolean
同步实体的数据。这个方法可能是在修改了实体的属性或者附加了新的数据之后调用的,以确保所有的改变都被正确地保存到实体的数据库记录中。

}else{
//同步失败
}

const ent = new McDbEntity()
let matrix = new McGeMatrix3d();
matrix.setToTranslation(new McGeVector3d(20,0,0));//平移
ent.transformBy(matrix);
