# Overlapping lumber around a door/window rough opening

### Problem

The system does not merge lumber, e.g., wall lumber around the vestibule and door frame lumber. The same applies to window and door frame structures.

### Vertification

Ensure that the visualization displays lumber without overlapping.

### Solutions

1. Move these elements apart.
2. If you want to merge, for example, the door rough opening structure with the window rough opening structure, you can do it yourself. The main structural beam can be the same for both. Remember to order a smaller amount of material.
