Clipping tool errror

When I try to use the clipping box for a section, nothing happens in my view , I can move the box wherever I want without a result, does anyone have an idea what I might be doing wrong?

Hello Tess,
Which version of Artlantis are you using ?
on macOS or Windows ?
Could you post a screenshot of the front and back view of the 2D View, to see if the clipping box is well positioned in Z
