Hi all,

I have something strange on an object.

This object have been made using boolean/intersection before extrusion.
I think it's the source of this probem.

My object noted with a size but if I click on size to edit it, the values are different.

An idea ?
It's not dramatic, but strange.

I use v4.0 beta 22 janv.
