-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.
