The Cone button on the Creation command panel lets you produce round cones, either upright or inverted.
Examples of cones
To create a cone:
On the Create menu choose Standard Primitives > Cone.
In any viewport, drag to define a radius for the base of the cone, then release to set it.
Move to up or down to define a height, either positive or negative, then click to set it.
Move to define a radius for the other end of the cone. Decrease this radius to 0 for a pointed cone.
Click to set the second radius and create the cone.
Edge—Draws a cone from edge to edge. You can change the center location by moving the mouse.
Center—Draws a cone from the center out.
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 Combinations | Effect |
|---|---|
| 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 off.
Smooth—Blends the faces of the cone, creating a smooth appearance in rendered views.
Slice On—Enables the Slice function. Default=off.
When you create a slice and then turn off Slice On, the complete cone reappears. You can 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 move it 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=off.
Note: If a visible viewport is set to a non-wireframe or non-bounding-box display, Generate Mapping Coordinates is on for all primitives to which you apply a material containing a map with Show Map In Viewport on. If all viewports are set to wireframe or bounding box, 3ds max turns on Generate Mapping Coordinates for primitives containing mapped materials at render time.
