```
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

  - DwgFile
```
public DwgFile(String filePath)
```
    Creates a new DwgFile object given the absolute path to a DWG file
    
    Parameters:
    
    filePath - an absolute path to the DWG file
- Method Detail
  - read
```
public void read()
          throws IOException
```
    Reads a DWG file and put its objects in the dwgObjects Vector This method is version independent
    
    Throws:
    
    IOException - If the file location is wrong
  - applyExtrusions
```
public void applyExtrusions()
```
    Modify the geometry of the objects applying the Extrusion vector where it is necessary
  - 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.
  - calculateCadModelDwgPolylines
```
public void calculateCadModelDwgPolylines()
```
    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.
  - blockManagement
```
public void blockManagement()
```
    Modify the geometry of the objects contained in the blocks of a DWG file and add these objects to the DWG object list.
  - initializeLayerTable
```
public void initializeLayerTable()
```
    Initialize a new Vector that contains the DWG file layers. Each layer have three parameters. These parameters are handle, name and color
  - getLayerName
```
public String getLayerName(DwgObject entity)
```
    Returns the name of the layer of a DWG object
    
    Parameters:
    
    entity - DWG object which we want to know its layer name
    
    Returns:
    
    String Layer name of the DWG object
  - getColorByLayer
```
public int getColorByLayer(DwgObject entity)
```
    Returns the color of the layer of a DWG object
    
    Parameters:
    
    entity - DWG object which we want to know its layer color
    
    Returns:
    
    int Layer color of the DWG object in the Autocad color code
  - testDwg3D
```
public void testDwg3D()
```
    Test if the DWG file is 2D or 3D. If there is any object with a non cero elevation value, the file is considered 3D.
