Southern Hemisphere project

[agk]

Hi  All,

I have a project in the southern hemisphere and need to be able to set the southings and westings rather than northings and eastings. I have not been able to get any sensible information out of AI.  I need to give the builder plans that allow them to locate the building from southings and westings. How do I set this up? I have told archicad the project location but the default eastings and northings are a problem as I can't get the numbers to behave properly when I try and use coordinate dimensions. 

many thanks,

Gail

Not that I use them but, it seems us southern folk use Eastings and Northings too.

Eastings are measured from the centre of a number of zones around the globe.

Each centre is given a false value of 500 000m so all Eastings are positive.

Northings are measured from the equator but down south the equator is given a false value of  10 000 000m, so the Northing value remains positive for us.

Just use something like Google and ask it to convert your latitude and longitude to Northings and Eastings.

There are on-line converters as well.

For me in Perth Western Australia ...

Hi Barry,

Thanks for replying. The project is in South Africa which seems to have its own system using southings and westings.  One of the graphisoft support people tried to help and suggested turning project north by 270 degrees to get the numbers to work, but I could not get the co-ordinate dimension tracker to work. I asked him to look at my file which he seemed happy to do, but now he has gone quiet and is no longer responding to messages.  In the end we pulled the drawing into Autocad and it just worked  - so pretty frustrating as we then had to pull the numbers manually back into ArchiCAD. It's really hard to believe there is no system for this!

Thank you anyway,

Gail
