Class: IMcDbDwgFiler ​

2d.IMcDbDwgFiler

Used for handling read and write operations of AutoCAD DWG files. This interface provides a set of methods that allow developers to read and write DWG files in the AutoCAD plugin.

Example

import { McDbCustomEntity, IMcDbDwgFiler } from "mxcad";
//Custom Entity Class Inherits McDbCCustoms Entity
  class McDbTestLineCustomEntity extends McDbCustomEntity {
//Define two point objects, pt1 and pt2, within the entity
       private pt1: McGePoint3d = new McGePoint3d();
       private pt2: McGePoint3d = new McGePoint3d();
//Read the data field pt1 of the custom entity pt2
       public dwgInFields(filter: IMcDbDwgFiler): boolean {
           this.pt1 = filter.readPoint("pt1").val;
           this.pt2 = filter.readPoint("pt2").val;
           return true;
       } 
//Write the data field pt1 to the custom entity pt2
       public dwgOutFields(filter: IMcDbDwgFiler): boolean {
           filter.writePoint("pt1", this.pt1);
           filter.writePoint("pt2", this.pt2);
           return true;
       }
  }
