yes but as my first volume is a 2 rails sweep (so Horizontal asymmetric side) maybe I can make that if the Rail Scale don't make half section
(not so a big deal :)

Hi Pilou, also when you start wanting to get a lot of control in many different areas like this, you may want to switch to the Network command instead. There you can add in a larger number of profiles.

But also it looks like assembling your object in halves works for your case too?

yes assembling works fine!
I was afraid that horizontal section shoud be different after the rail scaling but all works fine :)
