Dọn Dẹp (Clean Up)

These tools are to help cleanup degenerate geometry and fill in missing areas of a mesh.

Phân Rã Hình Học (Decimate Geometry)

Tham Chiếu (Reference)

Chế Độ (Mode): Chế Độ Biên Soạn (Edit Mode)
Trình Đơn (Menu): Mesh ‣ Clean up ‣ Decimate Geometry

The Decimate Geometry tool allows you to reduce the vertex/face count of a mesh with minimal shape changes.

Tỷ Số (Ratio)

Ratio of triangles to reduce to.

Vertex Group (Nhóm Điểm Đỉnh)

Use the active vertex group as an influence.

Trọng Lượng (Weight): Strength of the vertex group.
Đảo Nghịch (Invert): Inverts the vertex group.

Đối Xứng (Symmetry)

Maintain symmetry on either the X, Y, or Z axis.

This tool works similar to the Decimate Modifier.

Lấp Lỗ (Fill Holes)

Tham Chiếu (Reference)

Chế Độ (Mode): Chế Độ Biên Soạn (Edit Mode)
Trình Đơn (Menu): Mesh ‣ Clean up ‣ Fill Holes

This tool can take a large selection and detect the holes in the mesh, filling them in.

This is different from the face creation operator in three important respects:

Holes are detected, so there is no need to manually find and select the edges around the holes.
Holes can have a limit for the number of sides (so only quads or tris are filled in for example).
Mesh data is copied from surrounding geometry (UVs, Color Attributes, multi-res, all layers), since manually creating this data is very time-consuming.

Tạo Bề Mặt Bằng Phẳng (Make Planar Faces)

Tham Chiếu (Reference)

Chế Độ (Mode): Chế Độ Biên Soạn (Edit Mode)
Trình Đơn (Menu): Mesh ‣ Clean up ‣ Make Planar Faces

The Make Planar Faces iteratively flattens faces. This can happen with faces over three vertices and it is a common convention that faces should be kept planar.

Hệ Số (Factor): Distance to move the vertices each iteration.
Số Lần Lặp Lại (Iterations): Number of times to repeat the operation.

Phân Chia các Bề Mặt Không Phẳng (Split Non-Planar Faces)

Tham Chiếu (Reference)

Chế Độ (Mode): Chế Độ Biên Soạn (Edit Mode)
Trình Đơn (Menu): Mesh ‣ Clean up ‣ Split Non-Planar Faces

This tool avoids ambiguous areas of geometry by splitting non-flat faces when they are bent beyond a given limit.

Phân Chia các Bề Mặt Lõm (Split Concave Faces)

Tham Chiếu (Reference)

Chế Độ (Mode): Chế Độ Biên Soạn (Edit Mode)
Trình Đơn (Menu): Mesh ‣ Clean up ‣ Split Concave Faces

This tool can be used to convert any Concave Face to convex by splitting the concave into two or more convex faces.

Xóa Rời Rạc (Delete Loose)

Tham Chiếu (Reference)

Chế Độ (Mode): Chế Độ Biên Soạn (Edit Mode)
Trình Đơn (Menu): Mesh ‣ Clean up ‣ Delete Loose

This tool removes disconnected vertices and edges (optionally faces).

Tiêu Hủy có Suy Biến (Degenerate Dissolve)

Tham Chiếu (Reference)

Chế Độ (Mode): Chế Độ Biên Soạn (Edit Mode)
Trình Đơn (Menu): Mesh ‣ Clean up ‣ Degenerate Dissolve

This tool collapses / removes geometry which you typically will not want.

Edges with no length.
Faces with no areas (faces on a point or thin faces).
Face corners with no area.

Hội Nhập theo Khoảng Cách (Merge by Distance)

Tham Chiếu (Reference)

Chế Độ (Mode): Chế Độ Biên Soạn (Edit Mode)
Trình Đơn (Menu): Vertex ‣ Merge by Distance, Context Menu ‣ Merge by Distance

Merge by Distance is a useful tool to simplify a mesh by merging the selected vertices that are closer than a specified distance to each other. An alternative way to simplify a mesh is to use the Decimate Modifier.

Khoảng Cách Hội Nhập (Merge Distance): Sets the distance threshold for merging vertices.
Chưa Chọn (Unselected): Allows vertices in the selection to be merged with unselected vertices. When disabled, selected vertices will only be merged with other selected ones.
