Making a shape like the JWST's mirror

[micheus]

At Discord, an user asked for a way to make a shape like the JWST mirrors.
Despite other simple approaches, I come with this one intending to show the use of Magnet with Move, as well as the use of Put On [RMB] to create the "array".

Wow, great!

Also it's possible to use Deform - Inflate(RMB) in vertex selection mode instead of Magnet Move - by using a reference object.
Reference center point marked by orange color, radius point is in center of deformed plane (I selected four vertices around it), inflate value - 100%.
