Hi Hadri1, try this script here:

http://moi3d.com/forum/index.php?webtag=MOI&msg=2599.8

Once the cplane is set then inside the Project command click the "Use CPlane" button in the command options area.

To restore the cplane back to world coordinates you can use View > CPlane > "Reset CPlane" button, or right click View > CPlane, or set up a shortcut key with this:
script: moi.view.resetCPlane();

hi Michael,
Thanks a lot.
it works just fine.


to gain some time during selection of the projection axis.
i suggest to define the start and end points using the keyboard.
0 as the coordinates for the start point et 0,0,1 for the end points.
it is way faster than changing the view to seection the z axis.
