This page discusses specific selecting tools for curve objects in Edit Mode. The Curve Edit more also uses the general select tools used which are described in the interface section.

Curve selection in Edit Mode has fewer options than with meshes. Mainly this is, because there is only one selectable element type, the control points (no select mode needed here…). These points are a bit more complex than simple vertices, however, especially for Bézier curves, as there is the central vertex, and its two handles…

The basic tools are the same as with meshes, so you can select a simple control point with the LMB, add to current selection with Shift-LMB, Box Select B, and so on.

One word about the Bézier control points: when you select the main central vertex, the two handles are automatically selected too, so you can move it as a whole, without creating an angle in the curve. However, when you select a handle, only this vertex is selected, allowing you to modify this control vector…

Note that, unlike mesh edges, you cannot directly select a segment. Instead, select all of the control points that make up the segment you want to edit.

Select Menu

All A

Выбрать всё.

None Alt-A

Снять выделение.

Inverse Ctrl-I

Selects all the geometry that are not selected, and deselect currently selected components.

---

Box Select B

Interactive box selection.

Circle Select C

Interactive circle selection.

Lasso Select

Interactive free-form selection.

---

Select Random

Select random control points.

Checker Deselect

Select every Nth control point.

Select Linked Ctrl-L

Select control points that are connected to the current selection.

Select Similar Shift-G

Select control points that have similar properties to the current selection.

---

(De)select First/Last

Toggle the selection of the first or last control point(s).

Select Random

Справка

Mode:

Режим редактирования

Меню:

Select ‣ Select Random

Select Random control points.

Percent (Процент)

Selects the defined percentage of control points.

Random Seed

Seed used by the pseudo-random number generator.

Action

Controls whether the operator Selects or Deselects control points.

Checker Deselect

Справка

Mode:

Режим редактирования

Меню:

Select ‣ Checker Deselect

Этот инструмент применяет чередующийся шаблон выделенной/невыделенной клетки. Это работает только в том случае, если у вас уже выбрано более одной контрольной точки.

It works by changing the current selection so that only every Nth control points will remain selected, starting from the active one.

Deselected

Количество отменённых элементов в каждом повторении шаблона.

Selected

Количество выделенных элементов в каждом повторении шаблона.

Offset (смещение)

Смещение от начальной точки.

Select Linked

Справка

Mode:

Режим редактирования

Меню:

Select ‣ Select Linked

Горячая клавиша:

L, Ctrl-L, Shift-L

L (or Ctrl-L for all) will add to the selection the cursor’s nearest control point, and all the linked ones, i.e. all points belonging to the same curve. Note that for Bézier, using L with a handle selected will select the whole control point and all the linked ones.

Select Similar

Mode:

Режим редактирования

Меню:

Select ‣ Select Similar

Горячая клавиша:

Shift-G

Selects control points that have certain similar properties to the active one. The Настройки последней операции panel provides several selection options:

Type

Type

Selects splines that have the same spline Type i.e. Bézier, NURBS or Poly.

Radius (радиус)

Selects control points that have a similar Radius value.

Weight (вес)

Selects all points that have a similar Weight value.

Direction

Selects control points that have a similar handles direction.

Compare (сравнение)

Для количественных свойств это свойство выбирает тип сравнения двух числовых значений.

Equal (равно):

Выбирает элементы с тем же значением, что и выбранное свойство активного элемента.

Greater:

Выбирает элементы с бОльшим значением в качестве выбранного свойства активного элемента.

Less:

Выбирает элементы с меньшим значением в качестве выбранного свойства активного элемента.

Threshold

Для количественных свойств это свойство определяет, насколько близкими должны быть значения свойства при сравнении.

(De)select First/Last

Справка

Mode:

Режим редактирования

Меню:

Select ‣ (De)select First, Select ‣ (De)select Last

These operators will toggle the selection of the first or last control point(s) of the curve(s) in the object. This is useful to quickly find the start of a curve (e.g. when using it as path…).

Select Next/Previous

Справка

Mode:

Режим редактирования

Меню:

Select ‣ Select Next, Select ‣ Select Previous

These operators will select the next or previous control point(s), based on the current selection (i.e. the control points following or preceding the selected ones along the curve). In case of a cyclic curve, the first and last points are not considered as neighbors.

Select More/Less

Справка

Mode:

Режим редактирования

Меню:

Select ‣ More/Less

Горячая клавиша:

Ctrl-NumpadPlus, Ctrl-NumpadMinus

Their purpose, based on the currently selected control points, is to reduce or enlarge this selection.

Прочие узлы

For each selected control point, select all its linked points (i.e. one or two…).

Less

For each selected control point, if all points linked to this point are selected, keep this one selected. Otherwise, deselect it.

This implies two points:

1. When all control points of a curve are selected, nothing will happen (as for Less, all linked points are always selected, and of course, More cannot add any). Conversely, the same goes when no control points are selected.

2. Second, these tools will never «go outside» of a curve (they will never «jump» to another curve in the same object).

Pick Shortest Path

Справка

Mode:

Режим редактирования

Меню:

Menu Search ‣ Pick Shortest Path

Горячая клавиша:

Ctrl-LMB

Selects the curve segments between two control points: the active and the one under the cursor. In the case of a closed curve, the shortest path will be selected.
