DESCRIPTION

67       v.in.dxf converts DXF format CAD files to GRASS vector format. The fol‐
68       lowing graphical objects (DXF entities) are supported:
69
70           ·   point
71
72               ·   DXF POINT
73
74           ·   line
75
76               ·   DXF LINE
77
78               ·   DXF POLYLINE
79
80               ·   DXF LWPOLYLINE
81
82               ·   DXF ARC
83
84               ·   DXF CIRCLE
85
86               ·   DXF TEXT
87
88           ·   face
89
90               ·   DXF POLYFACE MESHES
91
92               ·   DXF 3DFACE
93       Table and column names are changed to lowercase characters  for  easier
94       SQL usage (lowercase table/column names avoid the need to quote them if
95       the attribute table is stored in a SQL DBMS such as PostgreSQL).
96
97       The "layer" column will contain the name(s) of the DXF input  layer(s).
98       The  DXF  entity  type  string will be stored in the "entity" column as
99       uppercase.
100
101       The "handle" column can be used to store small bits of data  associated
102       with  any  entity in the DXF file (i.e., entity handle or unique object
103       identifiers in the layer). The entity handle is a "text string of up to
104       16  hexadecimal  digits", which is a 64-bit integer (currently not sup‐
105       ported by GRASS database drivers).  For text type  entities,  the  text
106       value  will  be stored in the "label" column of the GRASS vector output
107       map. Neither the "handle" nor "label" column is mandatory.
