# ST_3DMakeBox

Introduction: Build a `Box3D` from two corner POINT Z geometries. Mirrors PostGIS's `ST_3DMakeBox`. The corners are taken verbatim — no swapping or validation of ordering — so inverted bounds are preserved as supplied. POINT inputs without a Z dimension contribute `z = 0`, matching PostGIS.

![ST_3DMakeBox builds a cuboid from two corner POINT Z geometries](../../../../image/box3d/st_3dmakebox.svg "ST_3DMakeBox: cuboid from two corner points")

Format: `ST_3DMakeBox(lowerLeft: Point, upperRight: Point)`

Return type: `Box3D`

Since: `v1.9.1`

SQL Example

```sql
SELECT ST_AsText(ST_3DMakeBox(ST_PointZ(1.0, 2.0, 3.0), ST_PointZ(4.0, 5.0, 6.0)))
```

Output:

```
BOX3D(1.0 2.0 3.0, 4.0 5.0 6.0)
```

Throws `IllegalArgumentException` if either argument is not a POINT. Returns `NULL` if either point is `NULL` or empty.
