A rectangular box with optional edge rounding. The most-used primitive for hard-surface modeling, and the shape the active tool spawns by default.

Parameters
- Size — base extent (default
2.0) - Half-Extents (X, Y, Z) — independent dimensions per axis, controlled by object scale
- Rounding + Profile — round any subset of edges by tuning rounding and profile
- Chamfer Smooth (Profile = Chamfer) — softens where the chamfer meets the faces
Notes
The Box’s single rounding value applies to every edge at once. Oblong is the same silhouette with the vertical corners and the horizontal rims controlled separately.
