Add Icosphere

Object Mode and Edit Mode

Tool

Toolbar ‣ Add Icosphere

Interactively add an Icosphere mesh object.

Usage

The tool works by first defining the base of the object by holding LMB and dragging to define size of the base. Next release the LMB and drag to define the height of the object. Finally, press LMB again to confirm the shape of the object.

You can also use the hotkeys below to constrain the object.

Ctrl

Toggles snapping on or off.

Alt

Toggles the Origin setting that is not the default.

Shift

Toggles the Aspect setting that is not the default.

Tool Settings

Depth

The initial depth used when placing the cursor.

Surface

Start placing on the surface, using the 3D cursor as a fallback.

Cursor Plane

Start placement using a point projected onto the orientation axis at the 3D cursor position.

Cursor View

Start placement using a point projected onto the view plane at the 3D cursor position.

Orientation

The alignment of the cursor when placing objects; defines the orientation of the base.

Surface

Align the object using the surface orientation, using the Transform Orientations as a fallback.

Default

Align the object using the default Transform Orientations.

Snap To

The target to use while Snapping.

Geometry

Snap to all types of geometry (vertices, edges, and faces).

Default

Snap to the snap target defined in the global Snapping controls.

Plane Axis

The axis used for placing the base region.

X

Use the X axis to place the base region.

Y

Use the Y axis to place the base region.

Z

Use the Z axis to place the base region.

Auto Axis

Select the closest axis when placing objects (surface overrides).

Base

Origin

The initial position of the base.

Edge

Places the object edge first and define the size of the base as the distance from the first edge to the adjacent edge.

Center

Places the object center first and define the size of the base as the distance from the base center to the perimeter.

Aspect

The initial setting for the aspect of the object’s base.

Free

Draws the length and width of the base using an unconstrained aspect.

Fixed

Draws the length and width of the base using a 1:1 aspect.

Height

Origin

The initial position of the height.

Edge

Places the object edge first and define the size of the height as the distance from the first edge to the adjacent edge.

Center

Places the object center first and define the size of the height as the distance from the base center to the perimeter.

Aspect

The initial setting for the aspect of the object’s height.

Free

Draws the length and width of the height using an unconstrained aspect.

Fixed

Draws the length and width of the height using a 1:1 aspect.

Subdivisions

How many vertices are used to define the sphere. At level 1 the icosphere is an icosahedron, a solid with 20 equilateral triangular faces. Each increase in the number of subdivisions splits each triangular face into four triangles.

Muista

Subdividing an icosphere raises the vertex count very quickly even with few iterations (10 times creates 5,242,880 triangles). Adding such a dense mesh is a sure way to cause the program to crash.
