   Parameters:
       input=name [required]
           Path to input DXF file

       output=name [required]

       layers=string[,string,...]
           List of DXF layers to import (default: all)

DESCRIPTION

       v.in.dxf converts DXF format CAD files to GRASS vector  format.  The  following  graphical  objects  (DXF
       entities) are supported:

           •   point

               •   DXF POINT

           •   line

               •   DXF LINEDXF POLYLINEDXF LWPOLYLINEDXF ARCDXF CIRCLEDXF TEXT

           •   face

               •   DXF POLYFACE MESHESDXF 3DFACE
       Table  and  column names are changed to lowercase characters for easier SQL usage (lowercase table/column
       names avoid the need to quote them if the attribute table is stored in a SQL DBMS such as PostgreSQL).

       The "layer" column will contain the name(s) of the DXF input layer(s). The DXF entity type string will be
       stored in the "entity" column as uppercase.

       The  "handle"  column  can be used to store small bits of data associated with any entity in the DXF file
       (i.e., entity handle or unique object identifiers in the layer). The entity handle is a "text  string  of
       up  to  16  hexadecimal  digits",  which  is  a 64-bit integer (currently not supported by GRASS database
       drivers).  For text type entities, the text value will be stored in  the  "label"  column  of  the  GRASS
       vector output map. Neither the "handle" nor "label" column is mandatory.
