Question

Blender

• How does it allocate one polygon at 4:11 ?
  
• How does it create the second polygon at 4:12 ?
  

Answer 1

Good evening!
4:11
You need to go into edit mode and press the number 3 (on top, not on our pad).
After that, you will switch to the face (polygon) selection mode.
4:12
After selecting a face (polygon), press the I key (English "ai").
I really hope I could help you.
Good luck!
