Dear ANTALIFE, yes, I try to do that, but results are the same, the official documentation of Altium say the next :
After launching the command, the entire workspace for the editor will be turned over (flipped).
All actions and editing commands are supported for flipped boards/components. The coordinate space remains logically the same, ie. the workspace origin moves from the bottom-left to the bottom-right. The current grid position increases in the X (horizontal) direction as you move the mouse from right to left, instead of the normal left to right. Any output generated while the view is flipped will maintain the correct 'viewed-from-top' coordinate information. me
I really dont know if that information means that its imposibble to correct the position of the axis on Flip Board ....
Thanks for your reply .
