Удалить и Растворить (delete & dissolve)

Удалить (delete)

Режим (mode):

Режим редактирования (edit mode)

Меню:

Меш ‣ Удалить Mesh ‣ Delete

Горячая клавиша:

X или Delete

Deletes the selected mesh elements. The following menu items are available:

Вершины (vertices)

Deletes the selected vertices, as well as any edges and faces they are part of.

Рёбра* (edges)

Deletes the selected edges, as well as any faces they are part of. Orphaned vertices are deleted too.

Грани (faces)

Deletes the selected faces. Orphaned vertices and edges are deleted too.

Только рёбра и грани (only edges & faces)

Deletes the selected edges and faces, as well as any unselected faces that contain a selected edge. Orphaned vertices are left behind.

Только грани (only faces)

Deletes the selected faces. Orphaned vertices and edges are left behind.

Растворить (dissolve)

Dissolving is different from deleting in that it keeps the surface closed rather than leaving a hole.

Меню:

Меш ‣ Удалить ‣ Растворить вершины Mesh ‣ Delete ‣ Dissolve Vertices

Горячая клавиша:

X, Delete, or Ctrl-X

Deletes each selected vertex and joins its surrounding faces into one. (This often results in n-gons.)

If a vertex is part of a wire – that is, a chain of edges that are not part of any face – its surrounding edges are merged instead.

Панель настройки последней операции предлагает следующие параметры:

Разделять грани (face split)

Split surrounding faces where possible so that only a triangle in their corner is merged instead of the whole face. This reduces the size of the final «hole-filling» faces and can make them less uneven.

Разрывать на границах (tear boundary)

Delete faces at the mesh boundary instead of merging them. These faces are always split, even if Face Split is disabled.

Растворить рёбра (dissolve edges)

Режим (mode):

Режим редактирования (edit mode)

Меню:

Меш ‣ Удалить ‣ Растворить рёбра Mesh ‣ Delete ‣ Dissolve Edges

Горячая клавиша:

X, Delete, or Ctrl-X

Deletes each selected edge and joins its surrounding faces into one. This is only done for edges that have exactly two neighboring faces.

The Adjust Last Operation panel offers the following options:

Растворить вершины (dissolve vertices)

Also dissolve the vertices of the selected edges, not just the edges themselves.

Пороговый угол (angle threshold)

If Dissolve Vertices is enabled, this option allows preserving vertices at corners, only dissolving the ones in flattish areas. Faces are considered to form a corner if the angle between their normals exceeds the Angle Threshold – that is, coplanar faces are considered to have an angle of 0°, not 180°.

Разделять грани (face split)

Split surrounding faces where possible so that only a triangle in their corner is merged instead of the whole face. This reduces the size of the final «hole-filling» faces and can make them less uneven.

Preserve Quads

Prevents vertices from being removed if doing so would break the quad structure when dissolving the edge between two triangles.

Even if Dissolve Vertices is enabled, vertices shared by the two triangles are kept so the resulting geometry remains a quad rather than collapsing into a triangle or n-gon.

This option helps maintain clean quad topology when simplifying meshes or removing unnecessary edges.

Горячая клавиша:

X, Delete, Ctrl-X, or F

Merges each patch of connected faces into a single face.

Примечание

The F shortcut is normally used for creating faces, but when run on a selection of existing faces, it dissolves them instead. See Растворение существующих граней.

Simplifies the selected geometry by dissolving vertices and edges in flattish areas.

Результат работы Limited Dissolve.

Максимальный угол (max angle)

The maximum allowed angle between faces for the surface to be considered flat (and thus eligible for dissolving). Specifically, the angle is measured between face normals, meaning that coplanar faces are considered to have an angle of 0°, not 180°.

Все границы (all boundaries)

After dissolving the edges using Max Angle, dissolve all vertices at boundary corners – specifically, vertices that only have two neighboring edges.

Разграничитель (delimit)

Prevent merging faces that are discontinuous in some way. It’s possible to activate multiple of these options by clicking them with Shift-LMB.

Нормаль (normal):

Don’t merge faces that have opposite orientations.

Материал (material):

Don’t merge faces that have different materials.

Шов (seam):

Don’t dissolve edges that are marked as UV Seams.

Острые (sharp):

Don’t dissolve edges that are marked as Sharp.

UV (UVs):

Don’t merge faces that are disconnected in any UV map.

Схлопнуть рёбра & грани (collapse edges & faces)

Режим редактирования (edit mode)

Меню:

Меш ‣ Удалить ‣ Схлопнуть рёбра & грани Mesh ‣ Delete ‣ Collapse Edges & Faces

Горячая клавиша:

X или Delete

Collapses each patch of connected edges and faces into a single vertex. This is useful for collapsing edge rings, for example.

Selected edge rings.

Edge rings collapsed.

Unlike the Dissolve operators, this operator doesn’t create n-gons and can add new vertices instead of only removing existing ones. In addition, the new vertices automatically receive interpolated UV coordinates, color attributes, etc. This makes it particularly useful for manually removing detail.

Петли рёбер (edge loops)

Режим редактирования (режим выделения Вершин и Рёбер)

Меню:

Меш ‣ Удалить ‣ Петли рёбер Mesh ‣ Delete ‣ Edge Loops

Горячая клавиша:

X или Delete

Dissolves the selected edge loops. This is essentially the same as Растворить рёбра (dissolve edges), except that it selects the surrounding faces afterwards.

Выделенная петля рёбер.

Edge loop dissolved.

Примечание

В терминологии Blender’а, петля рёбер – это любая цепочка соединённых рёбер; она не обязательно должна быть замкнутой. См. раздел «Выделить петли».
