So first is the mesh. Second is somewhat what i want to do, but simple grab makes it wrong. Of course i need faces to rotate accordingly. Like taking a carton and bending it in hands.
How can i achieve this?
I would start with a flat plane in “Top View”. Cut it in half and add a “Mirror Modifier”. Select the edge where you want the bend to take place then press “Shift” + “S” and select “Cursor to Selected” from the drop down menu.
Then change the “Pivot Center” to the 3D Cursor.
Then select the part of the plane you want to rotate and rotate around the 3D Cursor constrained to the “Y” axis. Press “R” + “Y” to accomplish this.
Then add a “Solidify Modifier”
I found a soulution - there are propably better ways, but here you go:
