I’m trying to reshape a cuboid rectangle. What I’d like to do is use the move tool to grab one of the top edges and then lower the height of that edge by about 10 - 20cm but using the cursor this is quite clunky because it can veer off in all different directions in 3D space.
It feels like there must be a way of locking the movement into the vertical plane so I only move the edge up or down?
I’ve attached a screen shot to show what I mean. It’s a little retaining wall that I’d like to zig zag a bit vertically, so one corner is 10cm higher than the previous, the next 10cm lower again etc.
