Edit tiling shape in 3D to fix alignment and stray lines
Adjust tiling alignment in 3D and clean up stray outline lines so the tiling follows the shape you want.
Tiling alignment can be adjusted by switching to 3D view, selecting the tiling, and using Edit Shape on the left side.
Extra or stray lines in the tiling outline (for example a jagged edge near a balcony) can be removed by deleting the unwanted lines and joining the remaining points into a straight line.
A room divider is not a physical wall and does not affect tiling.
