Cube
A six faced block, with corners that can be rounded.

The Cube is the most used primitive of the editor. Despite the name, it does not have to be cubic: the three measurements are independent, so the same primitive gives you a box, a board, a beam or a wall.
Properties
- Width, Height and Depth: Measurements of the block, in meters, on the X, Y and Z axes.
- Corner Radius: Rounds the edges of the block. At zero, the cube is sharp. The value is limited to half of the smallest of the three measurements.
- Corner Seg.: Number of divisions of the corner curve. With one segment the corner becomes a straight chamfer. It only has an effect with the radius above zero.
Topology
The cube is made of quads. With the corner radius above zero, each edge becomes a strip of quads and each corner becomes a piece of a sphere, which raises the polygon count considerably.
