An N-sided regular prism. Set the side count with the *Sides* enum.

![Prism](../../assets/prism.webp)

## Parameters

- **Sides** — `3`, `5`, `6`, or `8`
- **Apex Angle** *(triangular prisms only)* — `5°–175°` (default `60°`). Sharper or wider triangle profile.
- **Bevel** — vertical edge rounding, separate from the cap rounding
- **Bevel Profile** — Round / Sharp / Soft / Tight / Chamfer for the vertical edges
- **Bevel Smooth** *(when Bevel Profile = Chamfer)*
- **Rounding + Profile** — applies to the top and bottom rims

## Notes

The triangular prism is the only one whose cross-section is reshapeable: `Apex Angle` narrows or widens the triangle without changing the side count.

Side count and apex angle both have rows in the [`RMB` menu](../../interface/rmb-menu.md), so you can switch a hex to an octagon without opening the properties panel.
