Add Icosphere
Reference
- Mode
Object Mode and Edit Mode
- Tool
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
- 深度值（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.
Note
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.
