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