NAME

       v.in.dxf  - Converts file in DXF format to GRASS vector map.

KEYWORDS

       vector, import, DXF, level1

SYNOPSIS

       v.in.dxf
       v.in.dxf --help
       v.in.dxf  [-etbfli1]  input=name output=name  [layers=string[,string,...]]   [--overwrite]
       [--help]  [--verbose]  [--quiet]  [--ui]

   Flags:
       -e
           Ignore the map extent of DXF file

       -t
           Do not create attribute table

       -b
           Do not build topology
           Advantageous when handling a large number of points

       -f
           Import polyface meshes as 3D wire frame

       -l
           List available DXF layers and exit

       -i
           Invert selection by DXF layers (don’t import layers in list)

       -1
           Import all objects into one layer

       --overwrite
           Allow output files to overwrite existing files

       --help
           Print usage summary

       --verbose
           Verbose module output

       --quiet
           Quiet module output

       --ui
           Force launching GUI dialog

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

       output=name [required]
           Name for output vector map

       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 LINE

               ·   DXF POLYLINE

               ·   DXF LWPOLYLINE

               ·   DXF ARC

               ·   DXF CIRCLE

               ·   DXF TEXT

           ·   face

               ·   DXF POLYFACE MESHES

               ·   DXF 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.
