Cone

The Cone button on the Creation command panel produces round cones, either upright or inverted.

Reference

Cone Settings

The defaults produce a smooth, round cone of 24 sides with the pivot point at the center of the base. There are five height segments and one cap segment. For improved rendering, increase the number of height segments for smoothly shaded cones, particularly those with pointed tips.

Radius 1, Radius 2: Sets first and second radius for the cone. The minimum setting is 0. Minus values are converted to 0. You can combine these settings to create pointed and flat-topped cones, upright or inverted. The following combinations assume a positive height.

Radius 1 and Radius 2

Radius 2 is 0      Creates a pointed cone

Radius 1 is 0      Creates an inverted pointed cone

Radius 1 is larger than Radius 2      Creates a flat-topped cone

Radius 2 is larger than Radius 1      Creates an inverted flat-topped cone

If Radius 1 and 2 are the same, a cylinder is created. If the two radius settings are close in size, the effect is similar to applying a Taper modifier to a cylinder.

Effect of Radius settings

Height: Sets dimension along the central axis. Negative values create the cone below the construction plane.

Height Segments: Sets the number of divisions along the cone's major axis.

Cap Segments: Sets the number of concentric divisions around the center of the cone's top and bottom.

Sides: Sets the number of sides around the cone. Higher numbers shade and render as true circles with Smooth selected. Lower numbers create regular polygonal objects with Smooth clear.

Smooth: When selected (the default), faces of the cone are blended together, creating a smooth appearance in rendered views.

Slice On: Sets or clears the Slice feature. Default=clear.

When you create a slice and then uncheck Slice On, the complete cone reappears. You can therefore use this check box to switch between the two topologies.

Slice From, Slice To: Sets the number of degrees around the local Z axis from a zero point at the local X axis.

For both settings, positive values move the end of the slice counterclockwise, negative values, clockwise. Either setting can be made first. When the ends meet, the whole cone reappears.

Generate Mapping Coordinates: Sets up required coordinates for applying mapped materials to the cone. Default=clear.

How To

To create a cone:

1. In any viewport, drag to define a radius for the base of the cone, then release to set it.
2. Move to up or down to define a height, either positive or negative, then click to set it.
3. Move to define a radius for the other end of the cone. Decrease this radius to 0 for a pointed cone.
4. Click to set the second radius and create the cone.
