First thing to know is that there can be many MCS in a part, and you need to make one of them the active MCS. This requires being in the Manufacturing Applicaiton, and selecting or editing the mill_orient group, or one of the child operations.
This is what I would do interactively. You could do the same thing:
it's a good idea ,but i must to edit a operation or MCS for changing the WCS , select is not enough.
I am going to try to think every time of putting my wcs on my MCS.
I thought that it was easier than that !!
I finally found a solution.
From a character string, i create a 3D point which is related to my WCS
If anyone is interested, my code below.( i'm not a programmer ,there is certainly a more effective solution)
