Command: export

Syntax

export { <elist> ... }

Description

Dump entities and their graphics in export format.

Parameters

• <elist>
  A group/entity list defining which entities are to be dumped. If omitted, all entities are dumped.

Switches

• -buf=<num>
  When used with the -ch switch, indicates the size in bytes of eim (export format) packets. The default size is 16384.

• -c
  If the file (-of) exists, request confirmation from the user before it is overwritten.

• -ch=<channel>
  Sent the output to a binary channel (opened by open -li=<port>). The output will be wrapped in Fire Hose Protocol packets of type NET_PACKET_EIM.

• -com
  When used with the -ch switch, compress the data. This is the default behavior, use -no_com to suppress compression.

• -def
  Export symbology definitions where necessary. If this switch is omitted, symbology references are exported by name-only without definitions.

• -ef=<filter>
  A filter to be applied to all entities within <elist>, further qualifying which entities are to be dumped. If omitted, the filter current_filter is used.

• -full
  Export entities in full, with structure types and meta-data. If this switch is omitted, only graphic information is exported, without meta-data.

• -of=<file>
  An export file to be created. This or the -uof switch must be present. The default file extension is .eim.

• -uof=<string>
  Pipe the output to a unix filter program. This or the -of switch must be present.

• -vc=<text>
  Indicates the type of vector compression to be used. Possible values are:

i2_2d	x,y 2-byte integers
i2_3d	x,y,z 2-byte integers
i4_2d	x,y 4-byte integers
i4_3d	x,y,z 4-byte integers
r4_2d	x,y 4-byte floats
r4_3d	x,y,z 4-byte floats
r8_2d	x,y 8-byte floats
r8_3d	x,y,z 8-byte floats (the default)

Loss of information will necessarily occur with some compression types.

Notes

Sub-entities of compounds may not be exported in isolation from their parent entities. If this is attempted, the parent entity is also exported.

Export files may be read by the import command or by various external utility programs, e.g. eimprint.

Examples

Dump one entity to an import/export file.

export this, -of=this.eim

Dump all entities to a filter program.

export -uof="mx2dxf"
