Problem catia axes and reference point

Hello

I'm new to CATIA and I have a problem on my sketch with the configuration of my coordinate system: the vertical axis is connected to X and the horizontal axis to Z (and I would like the other way around). I can't change that...

Thanks in advance

Hello "positioned sketch".

If your sketch is already created "Right-click on it in the graph / Sketch object.../ Change the sketch support.

First field, the medium.

Second (optional but convenient) is the origin point of the sketch guide.

Third in the list select (for you either the axes, or // has a line).

Thank you!
