Is it possible to start your nodes at a coordinate apart from 0,0,0. I am analysis an existing system and i want my coordinates to align with the coordinates of the existing piping drawings. e.g the tie in point is at elevation 6 meters, North 13048mm and East 14511 of the field.

I will want my coordinates to start at exactly those positions

Yep, that is possible. I don't have CAESAR II here now, but I believe the button is on the same part is the element insert/delete/break function buttons. It looks like a globe/ball and after clicking it you can set global coordinates for your start node. This is also useful when you have 2 seperate lines which you want to evaluate in 1 calculation.

If your North is -X and East is -Z, then insert coordinate with sign "-"

Regards,

Thank you very much corne and danb, that helped much
