Of course, as everything is measured so nicely, it is easy enough to just move everything correctly given the correct amount of units to move it all … Anyway, I used the snapping tool, but:
- Extrude, not as such, but along the Y axis!! This way, the ground edge (which cannot be snapped to any geometry) stays on the ground
- I could just do “E Y -1”, but for the sake of the exercise, I just extruded, fixed on the Y-axis, and then snapped to the appropriate vertex on the top. As said, fixing on the Y-axis makes sure that the bottom stays OK
- Then, just select the top edge and merge it correctly (as in the video) … Here I forgot to auto-merge, which was interesting to see.
The main issue I had with the proposed solution is that the snapping of the bottom edge seems a bit “forced” because in this specific example we know the exact slope and we can snap to the grid … With another slope it would have been more problematic, I think.
