Trapezoid
A box with a smaller top. Cap sets how much smaller, from a pyramid (0) to a plain box (1). The side edges and the rims round separately, as on an Oblong.

Settings

| Setting | Default | Range | What it does |
|---|---|---|---|
| Cap | 0.5 | 0 – 1 (soft 0.9) | The top’s size as a share of the base: 0 a pyramid, 1 a box |
| Bevel Profile | Round | Round · Sharp · Soft · Tight · Chamfer | The shape of the side edges’ rounding |
| Bevel | 0 | ≥ 0 (soft 2) | Rounds the side edges |
| Bevel Smooth (Chamfer) | 0 | ≥ 0 (soft 0.5) | Rounds the seams where the side edges’ chamfer meets the faces |
| Profile | Round | Round · Sharp · Soft · Tight · Chamfer | Cap Rounding: the shape of the rims’ rounding |
| Rounding | 0 | ≥ 0 (soft 2) | Cap Rounding: rounds the top and bottom rims |
| Smooth (Chamfer) | 0 | ≥ 0 (soft 0.5) | Rounds the seams where the rims’ chamfer meets the faces |
The rows every shape has are in Properties Panels.
