.SH DESCRIPTION
\fIv.in.dxf\fR converts DXF format CAD files to GRASS vector
format. The following graphical objects (DXF entities) are supported:
.RS 4n
.IP \(bu 4n
point
.RS 4n
.IP \(bu 4n
\fBDXF POINT\fR
.RE
.IP \(bu 4n
line
.RS 4n
.IP \(bu 4n
\fBDXF LINE\fR
.IP \(bu 4n
\fBDXF POLYLINE\fR
.IP \(bu 4n
\fBDXF LWPOLYLINE\fR
.IP \(bu 4n
\fBDXF ARC\fR
.IP \(bu 4n
\fBDXF CIRCLE\fR
.IP \(bu 4n
\fBDXF TEXT\fR
.RE
.IP \(bu 4n
face
.RS 4n
.IP \(bu 4n
\fBDXF POLYFACE MESHES\fR
.IP \(bu 4n
\fBDXF 3DFACE\fR
.RE
.RE
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).
.PP
The \(dqlayer\(dq column will contain the name(s) of the DXF input
layer(s). The DXF entity type string will be stored in the \(dqentity\(dq
column as uppercase.
.PP
The \(dqhandle\(dq 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 \(dqtext string of up
to 16 hexadecimal digits\(dq, 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 \(dqlabel\(dq column of the GRASS vector
output map. Neither the \(dqhandle\(dq nor \(dqlabel\(dq column is mandatory.
