Taken a bit different approach than in instructions to finish up the ‘barriers’ -
- top: extrude face + rotate face (pivot point at bottom) + extrude - seems less hassle
- bottom: extrude face + move bottom edge on y snap to top + extrude + move top edge on y stap to bottom (or sth like that - hard to explain) - a bit extra geometry but no need to zoom in and align ‘manually’
Stairs… as in example.
