A common object type used in a 3D scene is a mesh. Blender comes with a number of "primitive" mesh shapes that you can start modeling from. You can also add primitives in Edit Mode at the 3D cursor.
Blender's standard primitives.¶

Planar Primitives
You can make a planar mesh three-dimensional by moving one or more of the vertices out of its plane (applies to Plane, Circle and Grid). A simple circle is often used as a starting point to create even the most complex of meshes.
Tùy Chọn Chung -- Common Options¶
These options can be specified in the Adjust Last Operation panel, which appears when the object is created. Options included in more than one primitive are:
- Sinh Tạo các UV -- Generate UVs
Generates a default UV unwrapping of new geometry. This will be defined in the first UV layer (which will get added if needed).
- Radius/Size, Align to View, Location, Rotation

Mặt Phẳng -- Plane¶
The standard plane is a single quad face, which is composed of four vertices, four edges, and one face. It is like a piece of paper lying on a table; it is not a three-dimensional object because it is flat and has no thickness. Objects that can be created with planes include floors, tabletops, or mirrors.
Lập Thể -- Cube¶
A standard cube contains eight vertices, twelve edges, and six faces, and is a three-dimensional object. Objects that can be created out of cubes include dice, boxes, or crates.
Hình Tròn -- Circle¶
- Điểm Đỉnh -- Vertices
The number of vertices that define the circle or polygon.
- Thể Loại Phủ Kín -- Fill Type
Set how the circle will be filled.
- Hình Rẻ Quạt -- Triangle Fan
Fill with triangular faces which share a vertex in the middle.
- Đa Giác -- N-gon
Fill with a single N-gon.
- Không -- Nothing
Do not fill. Creates only the outer ring of vertices.
Hình Cầu UV -- UV Sphere¶
A standard UV sphere is made out of quad faces and a triangle fan at the top and bottom. It can be used for texturing.
- Phân Đoạn -- Segments
Number of vertical segments. Like the Earth's meridians, going pole to pole.
- Vành Nhẫn -- Rings
Number of horizontal segments. These are like the Earth's parallels.
Ghi chú
Rings are face loops and not edge loops, which would be one less.
Nhị Thập Diện Cầu -- Icosphere¶
An icosphere is a polyhedral sphere made up of triangles. Icospheres are normally used to achieve a more isotropical layout of vertices than a UV sphere, in other words, they are uniform in every direction.
- Lượng Phân Hóa -- Subdivisions
How many recursions 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.
Ghi chú
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.
Hình Trụ -- Cylinder¶
Objects that can be created out of cylinders include handles or rods.
- Điểm Đỉnh -- Vertices
The number of vertical edges between the circles used to define the cylinder or prism.
- Chiều/Độ Sâu -- Depth
Sets the starting height of the cylinder.
- Loại Hình Học Phủ Đầu -- Cap Fill Type
Similar to circle (see above). When set to none, the created object will be a tube. Objects that can be created out of tubes include pipes or drinking glasses (the basic difference between a cylinder and a tube is that the former has closed ends).
Hình Nón -- Cone¶
Objects that can be created out of cones include spikes or pointed hats.
- Điểm Đỉnh -- Vertices
The number of vertical edges between the circles or tip, used to define the cone or pyramid.
- Bán Kính 1 -- Radius 1
Sets the radius of the circular base of the cone.
- Bán Kính 2 -- Radius 2
Sets the radius of the tip of the cone. Which will create a frustum (a pyramid or cone with the top cut off). A value of 0 will produce a standard cone shape.
- Chiều/Độ Sâu -- Depth
Sets the starting height of the cone.
- Loại Hình Học Phủ Đáy -- Base Fill Type
Similar to circle (see above).
Hình Xuyến -- Torus¶
A doughnut-shaped primitive created by rotating a circle around an axis. The overall dimensions can be defined by two methods.
- Sắp Đặt Sẵn của Toán Tử -- Operator Presets
Torus preset settings for reuse. These presets are stored as scripts in the proper presets directory.
- Số Phân Đoạn của Vòng -- Major Segments
Number of segments for the main ring of the torus. If you think of a torus as a "spin" operation around an axis, this is how many steps are in the spin.
- Minor Segments
Number of segments for the minor ring of the torus. This is the number of vertices of each circular segment.
- Dimensions Mode
Change the way the torus is defined.
Major/Minor, Exterior/Interior
- Bán Kính Vòng -- Major Radius
Radius from the origin to the center of the cross sections.
- Bán Kính Mặt Cắt -- Minor Radius
Radius of the torus' cross section.
- Bán Kính Ngoại -- Exterior Radius
If viewed along the major axis, this is the radius from the center to the outer edge.
- Bán Kính Nội -- Interior Radius
If viewed along the major axis, this is the radius of the hole in the center.
Đồ Thị -- Grid¶
A regular quadratic grid which is a subdivided plane. Example objects that can be created out of grids include landscapes and organic surfaces.
- Lượng Phân Hóa X -- X Subdivisions
The number of spans in the X axis.
- Lượng Phân Hóa Y -- Y Subdivisions
The number of spans in the Y axis.
Đầu Khỉ -- Monkey¶
This adds a stylized monkey head to use as a test mesh, use Subdivision Surface for a refined shape.
This is intended as a test mesh, similar to:

History
This is a gift from old NaN to the community and is seen as a programmer's joke or "Easter Egg". It creates a monkey's head once you press the Monkey button. The Monkey's name is "Suzanne" and is Blender's mascot.

Trình Bổ Sung -- Add-ons
In addition to the basic geometric primitives, Blender has a number of script generated meshes to offer as pre-installed add-ons. These are available when enabled in the Preferences (select the Category Add Mesh, then check any desired items).
