Ấn Định một Nhóm Điểm Đỉnh (Assigning a Vertex Group)
Tạo Nhóm Điểm Đỉnh (Creating Vertex Groups)
Nhân Nhóm Điểm Đỉnh với Vỏ Bao.
Vertex groups are maintained within the Object Data tab (1) in the Properties. As long as no vertex groups are defined (the default for new mesh objects), the panel is empty (2).
You create a vertex group by LMB on the Add button + on the right panel border (3).
Initially the group is named "Group" (or "Group.nnn" when the name already exists) and
gets displayed in the panel (2) (see next image).
Các Điều Khiển của Bảng Nhóm Điểm Đỉnh (Vertex Groups Panel Controls)
One vertex group.
Once a new vertex group has been added, the new group appears in the Vertex Groups panel. There you find three clickable elements:
- Tên Nhóm (Group Name)
The group name can be changed by double-clicking LMB on the name itself. Then you can edit the name as you like.
- Thanh Lọc [biểu tượng hình mũi tên] (Filter [arrow icon])
When the little arrow icon in the left lower corner is clicked, a new row opens up where you can enter a search term. This becomes handy when the number of vertex groups gets big.
- Tay cầm để Kéo Rê (Drag Handle)
If you have a large number of vertex groups and you want to see more than a few groups, you can LMB on the small drag handle to make the vertex groups list larger or smaller.
- Nhóm đang hoạt động (Active Group)
When a vertex group is created, then it is also automatically marked as the Active Group. This is indicated by setting the background of the panel entry to a light gray color. If you have two or more groups in the list, then you can change the active group by LMB on the corresponding entry in the Vertex Groups panel.
Xóa các Nhóm Điểm Đỉnh (Deleting Vertex Groups)
Delete a vertex group.
You delete a vertex group by first making it the active group
(select it in the panel) and then LMB
the Remove button - at the right panel border.
Deleting a vertex group only deletes the vertex assignments to the group. The vertices themselves are not deleted.
Khóa các Nhóm Điểm Đỉnh (Locking Vertex Groups)
Lock a vertex group.
Right after creation of a vertex group, an open padlock icon shows up on the right side of the list entry. This icon indicates that the vertex group can be edited. You can add vertex assignments to the group or remove assignments from the group. And you can change it with the weight paint brushes, etc.
When you click on the icon, it changes to a closed padlock icon and all vertex group modifications get disabled. You can only rename or delete the group, and unlock it again. No other operations are allowed on locked vertex groups, thus all corresponding buttons become disabled for locked vertex groups.
Làm Việc với Nội Dung của các Nhóm Điểm Đỉnh (Working with Content of Vertex Groups)
Ấn Định Điểm Đỉnh cho một Nhóm (Assigning Vertices to a Group)
Assign weights to active group.
You add vertices to a group as follows:
Select the group from the group list, thus making it the active group (1).
From the 3D Viewport select Shift-LMB all vertices that you want to add to the group.
Set the weight value that shall be assigned to all selected vertices (2).
LMB the Assign button to assign the selected vertices to the active group using the given weight (3).
Note that weight assignment is not available for locked vertex groups. The Assign button is grayed out in that case.

Ấn định là gia tăng bổ sung
The Assign button only adds the currently selected vertices to the active group. Vertices already assigned to the group are not removed from the group.
Also keep in mind that a vertex can be assigned to multiple groups.
Kiểm Tra Sự Ấn Định (Checking Assignments)
To be sure the selected vertices are in the desired vertex group, you can try press the deselect button. If the vertices remain selected then they are not yet in the current vertex group.
At this point you may assign them, but take care since all selected vertices will have their weight set to the value in the Weight: field.
Xóa các Ấn Định từ một Nhóm (Removing Assignments from a Group)
You remove vertices from a group as follows:
Select the group from the group list (make it the active group).
Select all vertices that you want to remove from the group.
LMB click the Remove button.
Note that removing weight assignments is not available for locked vertex groups. The Remove button is grayed out in that case.
Sử Dụng Nhóm để Lựa Chọn/Hủy Chọn (Using Groups for Selecting/Deselecting)
You can quickly select all assigned vertices of a group:
(Optionally) press Alt-A to deselect all vertices.
Select the group from the group list (make it the active group).
When you now LMB click the Select button, then the vertices assigned to the active group will be selected and highlighted in the 3D Viewport.
When you LMB click the Deselect button instead, then the vertices assigned to the active group will be deselected in the 3D Viewport.
Ghi chú
Selecting/Deselecting is additive
If you already have vertices selected in the 3D Viewport, then selecting the vertices of a group will add the vertices but also keep the already selected vertices selected. Vice versa, deselecting the vertices of a vertex group will only deselect the vertices assigned to the group and keep all other vertices selected.

You can find ungrouped vertices as follows:
Press Alt-A to deselect all vertices.
