```
public class DwgFile
extends Object
```
The DwgFile class provides a revision-neutral interface for reading and handling DWG files Reading methods are useful for reading DWG files, and handling methods like calculateDwgPolylines() are useful for handling more complex objects in the DWG file

  - calculateGisModelDwgPolylines
```
public void calculateGisModelDwgPolylines()
```
    Configure the geometry of the polylines in a DWG file from the vertex list in this DWG file. This geometry is given by an array of Points. Besides, manage closed polylines and polylines with bulges in a GIS Data model. It means that the arcs of the polylines will be done through a set of points and a distance between these points.
  - blockManagement2
```
public void blockManagement2()
```
    Configure the geometry of the polylines in a DWG file from the vertex list in this DWG file. This geometry is given by an array of Points Besides, manage closed polylines and polylines with bulges in a GIS Data model. It means that the arcs of the polylines will be done through a curvature parameter called bulge associated with the points of the polyline.
