Hi guys, I was designing a little bird and have been drawing wireframes first and made surfaces out of them.

After this I could ‘judge’ the volume of the shape by eye/feeling and I have moved around the points (F10) to get the correct voluminous shape I wanted. However, of course, after moving the points, the surfaces weren’t flat anymore, but they had a curve:

Now what I am looking for is a command that can split the curved surfaces into two surfaces that then look like this:

I hope it’s clear, already tried every combination there is in the menus so there must be something I’m missing. I am pretty sure this is probably some very simple thing to do. Like ‘flatten and split surfaces’ or something.

Let’s hope there is a way!

Thanks for your energy,

Marinus
