Currently freestanding walls can cross on beams (not actually cross, but you can begin 2 walls brom the same block, making them share a corner). However no more than 2 walls can make a corner like that, meaning you can’t make 3 or 4 walls start/end on the same beam (while geometry suggests otherwise).
Steps to reproduce:
- Draw a rectangular foundation.
- Draw a freestanding wall on it
- Draw another freestanding wall starting from the same beam as the first one
- Attemp to draw third wall starting (or ending) on the same beam
Geometry allows up to 4 walls starting from the same point, so the player expects as much.
Such walls are limited to 2.
Walls created by “raise walls” instrument do not support such technique at all.
