Cone

A cone joining a circular base to a single apex point.

Cone joins a circular base to a single apex. Lowering Sides turns it into a pyramid.

Geometry

A circular base plus a side wall, with a single vertex at the apex. The pivot is at the center of the base, so a cone of height h occupies y=0 to y=h.

Sides at 3 gives a triangular pyramid, 4 a square pyramid, 6 a hexagonal pyramid.

Parameters

Label	Script key	Default	Range	Description
Radius	`r`	1	0.01 ~ 1000	Radius of the base circle, in meters
Height	`h`	1	-1000 ~ 1000	Height in meters
Sides	`sides`	12	3 ~ 128	Divisions around the base

How to create

Drag in empty space to set the radius of the base circle.
Click to confirm, then move the mouse up to set the Height.
Click again to finish.

The ±X and ±Z handles drive Radius and the ±Y handles drive Height.

Tips

For a truncated cone, use Pipe or convert to an editable mesh and inset/move the apex — the parameters alone cannot produce a frustum.

Common for roofs, spikes and nails; Sides=4 gives a pyramid.

Script

In a script this shape is written as cone.

cone "Roof" r=2 h=1.5 sides=4 @0,3,0
