NAME
	Read DXF - reads in an AutoCad DXF file and creates AVS geometries
        based upon input data types and level information

DESCRIPTION

   Read DXF is a utility module for converting 2D and 3D DXF files 
   into an AVS Geometry Data Type. If level information is available
   in the DXF file, Read DXF will use this to create separate objects.
   DXF is the file type for autoCAD output.

   Supported Entities :   LINE

                          POLYLINE

                          3DFACE

                          BLOCK
 
                          LEVEL

  Read DXF can be easily modified to handle more primitives,
  ie. points, arcs, & circles. All of the DXF header information
  is overlooked. If Read DXF encounters a primitive it doesn't understand
  it dumps out a geometry of what it had generated to that point, plus
  a message with the code number , the command to interpret, and the
  current layer name.

INPUTS
       DXF file

PARAMETERS

Smooth (toggle)
   
   Smooth forces the creation of surface normals for all 3DFACES in a
   way that will result in a smoother shading of the surface.
   

OUTPUTS
	output - geom
