R-click on a line and select position and size, then select the tab of
the same name. This shows the position (x,y) of one end of the line plus
the distance (delta_x, delta_y) to the other end. It's not hard to add
them together :-) And arguably the existing way is the more useful.

(BTW, if you start a new topic, please don't just reply to and change
the subject line of an existing email. That causes your message to
appear down in the depths of another thread of conversation, where it
may be unseen by those who might otherwise offer help.)

Hi Mark

Thank you for that advice but what I am looking for is a file of all
of the coordinates so that I could do additional things with them
outside openoffice.

I am using this for architectural work as an alternative to
autocad. Clients love the colour coding it enables.

Kind regards
David

Hi David,

an ODG document is just a zip file. So you can open it with any
zip tool (maybe have to rename it to .zip). In this zip is a
content.xml. For each line you find something like this

<draw:line draw:style-name="gr1" draw:text-style-name="P1"
draw:layer="layout" svg:x1="8cm" svg:y1="9.5cm" svg:x2="16.5cm"
svg:y2="13cm">

Now this line goes from 8cm/9.5cm to 16cm/13cm.

There are many tools to deal with zip and xml. If you know
java you can google for "odf toolkit". Another option is
to write a basic macro or OOo extension to export all lines.

Regards,
Christian

I've just put the appended perl script together. No pretenses about good
coding, and it makes probably unwarranted assumptions about the xml file
structure. It prints a list of the straight lines in a drawing as
x1 y1 x2 y2 text
tab separated.
No concessions to weird characters or xml quirks, but gives a flavour of
what a naive approach to xml parsing can do. May offer ideas at least.

(You may have trouble with line wrap; in particular the text starting
"$xml =~ " is supposed to be a single line). Oh, usual disclaimer -
supplied as-is, no warranty, check it yourself, use at own risk, don't
blame me if your computer blows up or the world comes to an end :-)

#!/usr/bin/perl -w

use Archive::Zip;
use Archive::Zip::MemberRead;

die "no file given\n" unless $ARGV[0];

# load the xml into one long string
$zip = Archive::Zip->new($ARGV[0]) or die "ooops!\n";
$fh = Archive::Zip::MemberRead->new($zip, "content.xml") or die "no
content.xml\n";

my $xml = '';

while (defined(my $line = $fh->getline())) {
$xml .= ' ' . $line;
}

$fh->close();

# parse out the lines and print the coordinate
while(1) {
$xml =~ m~<draw:line[^>]+?svg:x1="([^"]+?)" svg:y1="([^"]+?)"
svg:x2="([^"]+?)"
svg:y2="([^"]+?)"><text:p[^>]+>([^<]*?)</text:p></draw:line>(.*)$~ or last;
##<draw:line draw:style-name="gr1" draw:text-style-name="P2"
draw:layer="layout" svg:x1="7cm" svg:y1="18cm" svg:x2="16cm"
svg:y2="12.5cm"><text:p text:style-name="P1">Line two</text:p></draw:line>

print "$1\t$2\t$3\t$4\t$5\n";

$xml = $6;
}
