Currently myself is using Caesar2 Release 5.1. The co ordinate system icon, when it is viewed from the top has the Positive(+) X-axis going towards the left (towards west). The positive part of the Z-axis going upwards (towards north. The CAD drafting tools like Auto cad etc have the positive X-axis set towards the east direction. Is there any specific reason for Caesar2 having the positive x direction towards left. Why not it match with the common cad tools. This will help comparing the Cad models easly with the CAESAR II model. This together with the WRC coordinates or API610 co ordinates creates mis understanding. Any response!
