Class: McDbProxyEntity ​

2d.McDbProxyEntity

Proxy entity type is a special type of entity whose geometric shape and attribute information are stored in external sources, such as external files or databases.

Example

//Traverse the text in the proxy entity
import { MxCADSelectionSet, McDbProxyEntity } from "mxcad";

let ss = new MxCADSelectionSet();//  Construct selection set objects
//Set filter
let filter = new MxCADResbuf();
filter.AddMcDbEntityTypes("TEXT,MTEXT,INSERT,ACAD_PROXY_ENTITY");
ss.allSelect(filter);//  Filter all text, blocks, and proxy entity objects on the drawing
//Traverse and select objects
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 (Traverse Text, val);
   });
})
