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%.

Hello guys,

Nice little model. I guess that the easiest way would be to use the 'GeoDome' primitive. Here is a 6-step making-of :

• Step 1 : Create a 'GeoDome' primitive at resolution 6 / View along Z to get image in Figure 1
  
• Step 2 : Select all vertices and apply a Bevel of 0.072 to create 350 hexagons and 12 pentagons
  
• Step 3 : Select 1 hexagon that is equidistant from its 3 neighboring pentagons / Hit I (= select similar faces) then + and + (select 2 layers of neighbors) to get 20 patterns of 19 hexagons, arranged like the James Webb Space Telescope.
  
• Step 4 : Apply Shell Extrude Normal 0.02 and delete initial GeoDome to get 20 telescope mirrors pointing towards the origin
  
• Step 5 : Apply Explode Uniform -200% to make all the mirrors facing outer space, which is more useful for a telescope
  
• Step 6 : Put the Earth at the origin, and you've got your 20 orbiting telescopes, much better than the NASA ;-)

Nice entries guys! Thanks for sharing.

I liked you approach sciroccorics. It will create a more accurate curvature.
