# Overlapping Wall Studs / Floor Joists

### Problem

The system always maintains a fixed spacing between lumbers, which can result in overlap at the ends of the wall/floor/ceiling. This specifically applies to the last and second-to-last beams of the wall/floor/ceiling.

### Verification

Ensure that the visualization displays lumber without overlapping.

### Solutions

1. If possible, increase the wall dimension.
2. When ordering wood, order one lumber less. During construction, do not install the second-to-last lumber that was overlapping in the visualization. Remember that the distance between the new second-to-last lumber and the last lumber will be larger, which will require placing insulation in a non-standard way.
3. When assembling the wall, move it to the center, i.e., between the last and the second-to-last lumber. In this case, you will also place insulation in a non-standard way.
