Knife Tool¶
The Knife tool can be used to interactively subdivide (cut up) geometry by drawing lines or closed loops to create holes.
Usage¶
When you press K (or Shift-K ), the Knife tool becomes active.
Drawing the Cut Line¶
When using Knife, the cursor changes to an icon of a scalpel and the header changes to display options for the tool. You can draw connected straight lines by clicking LMB , marked with small green squares. Red squares are already defined cuts. Surrounding red squares mean that there is a cut already in that very position, so no additional vertex will be created (besides the first one).
Mesh before knife cut.
Knife cut active.
After confirming knife cut.
Options¶
Creating multiple cuts.
Result of starting new cuts while in the tool.
Constraining cut angle.
Result of constraining cut angle.
Confirming and Selection¶
Pressing Esc or RMB at any time cancels the tool, and pressing LMB or Return confirms the cut, with the following options:
Return will leave selected every edge except the new edges created from the cut.
Knife Project¶
| Mode: | Edit Mode |
|---|---|
| Panel: | Toolbar ‣ Tools ‣ Mesh Tools ‣ Add: Knife Project |
Knife projection is a non-interactive tool where you can use objects to cookie-cut into the mesh rather than hand drawing the line.
This works by using the outlines of other selected objects in Edit Mode to cut into the mesh along the view axis, resulting geometry inside the cutters outline will be selected.
Outlines can be wire or boundary edges.
To use Knife Project, first while in Object Mode, select the «cutting object» then add to that selection with Shift-RMB the «object to be cut». Now, enter Edit Mode and press Knife Project (found in the Toolbar).
3D View Alignment to adjust the projection axis.
Examples¶
Before projecting from a text object.
Resulting knife projection.
Before projecting from a mesh object.
Resulting knife projection (extruded after).
Before projecting from a 3D curve object.
Resulting knife projection (extruded after).
Known Limitations¶
Duplicate Vertices¶
If you experience problems where duplicate vertices are being created by cuts, this is often caused by too large a near/far clipping range.
Try increasing the Clip Start to avoid this problem, see Depth Troubleshooting for details.
Unconnected Cuts¶
Cuts that begin or end in the middle of a face, will be ignored.
This is constrained by the kinds of geometry Blender can represent.

Как отрезать часть объекта?
Нужно ровно отрезать нижнюю часть объекта:
Так и не нашел, как это сделать. В режиме Wireframe сетка не появляется.
Файл отсюда.
Пробовал зажать Shift при выбранном инструменте Нож, не помогло.
Наверняка в пару кликов можно сделать.
Кнопка Y на скриншоте в нажатом положении или в отжатом?
Хотел развернуть вид справа на весь экран при помощи Ctrl + arrow up — не срабатывает. Как развернуть?

У ножа вместо удержания шифта надо включить привязку C, и еще сквозную резку Z
Y — отжата. В дефолтной теме нажатые кнопки — темно-серые.
В режиме ножа разворачивание окна не срабатывает.
- Вконтакте
Но я не в режиме ножа разворачиваю. Открыл программу, не включал никакие режимы, жму CTRL + UP, а вместо того, чтобы развернуть на весь экран, скрывает панель со шкалой внизу.
Как разрезать объект по линии
1. Выделите линию разреза (быстрее это сделать с помощью клавиши Ctrl).
2. Перейдите в режим выделения вершин.
3. Скройте линию разреза (клавиша H).
4. Наведите мышь на одну из частей и нажмите L для выделения связанных вершин.
5. Верните скрытые вершины комбинацией Alt+H.
6. Нажмите P и выберите Selection для отделения выбранной области от объекта.
