Кривая (curve)

This page covers the basics of curve editing.

Трансформировать (transform)

Режим редактирования (edit mode)

Меню:

Curve ‣ Transform

A Bézier curve can be edited by transforming the locations of both control points and handles. NURBS curve on the other hand have only control points.

Переместить, Вращать, Масштабировать (move, rotate, scale)

Like other elements in Blender, curve control points and handles can be moved, rotated, or scaled as described in Basic Transformations.

To Sphere, Shear, Bend, Push/Pull, Warp, Randomize

The transform tools are described in the Transformations sections.

Переместить/масштабировать пространство текстуры

Like other objects, curves have textures spaces which can be edited.

Радиус (radius)

Режим редактирования (edit mode)

Инструмент (tool):

Toolbar ‣ Radius

Меню:

Curve ‣ Transform ‣ Radius

Горячая клавиша:

Alt-S

Controls the width of the extrusion along the «spinal» curve. The radius will be interpolated from point to point (you can check it with the normals). The Radius of the points is set using the Radius transform tool. Or in the Sidebar Transform panel.

One control point radius set to zero.

Зеркало (mirror)

Curve ‣ Mirror

Горячая клавиша:

Ctrl-M

The Mirror tool is also available, behaving exactly as with mesh vertices.

Привязать (snap)

Режим (mode):

Режим редактирования (edit mode)

Меню:

Curve ‣ Snap

Горячая клавиша:

Shift-S

Mesh snapping also works with curve components. Both control points and their handles will be affected by snapping, except for within itself (other components of the active curve). Snapping works with 2D curves but points will be constrained to the local XY axes.

Прокрутить / Оборот (spin)

Меню:

Curve ‣ Spin

The Spin operator only works for one dimensional surface objects. Its use for curves is currently not possible, the full feature is documented in Surface editing.

Add Duplicate

Режим (mode):

Режим редактирования (edit mode)

Меню:

Curve ‣ Add Duplicate

Горячая клавиша:

Shift-D

Duplicates the selected control points, along with the curve segments implicitly selected (if any). If only a handle is selected, the full point will be duplicated too. The copy is selected so you can move it to another place.

Разделить (split)

Ссылка

Режим (mode):

Режим редактирования (edit mode)

Меню:

Curve ‣ Split

Горячая клавиша:

Y

Splits a selected segment of a curve from the rest of the curve. This curve can then be moved or altered without affecting the other curve. If a single control point is selected the Split operator will create a new singular loose control point; leaving the previously selected control point attached to the rest of the curve.

Отделить (separate)

Ссылка

Режим (mode):

Режим редактирования (edit mode)

Меню:

Curve ‣ Separate

Горячая клавиша:

P

Separates curve objects that are made of multiple distinct curves into their own objects.

Note, if there is only one curve in a Curve object, This operation will create a new Curve object with no control points.

Toggle Cyclic

Ссылка

Режим (mode):

Режим редактирования (edit mode)

Меню:

Curve ‣ Toggle Cyclic

Горячая клавиша:

Alt-C

Toggles between an open curve and closed curve (Cyclic). Only curves with at least one selected control point will be closed/open. The shape of the closing segment is based on the start and end handles for Bézier curves, and as usual on adjacent control points for NURBS. The only time a handle is adjusted after closing is if the handle is an Auto one. Fig. Open and Closed curves. is the same Bézier curve open and closed.

This action only works on the original starting control point or the last control point added. Deleting a segment(s) does not change how the action applies; it still operates only on the starting and last control points. This means that Alt-C may actually join two curves instead of closing a single curve! Remember that when a 2D curve is closed, it creates a renderable flat face.

Open and Closed curves.

Set Spline Type

Режим (mode):

Режим редактирования (edit mode)

Меню:

Curve ‣ Set Spline Type

Converts splines in a curve object between Bézier, NURBS, and Poly curves. Note, this is not a «smart» conversion, i.e. Blender does not try to keep the same shape, nor the same number of control points. For example, when converting a NURBS to a Bézier, each group of three NURBS control points become a unique Bézier one (center point and two handles).

Отображать/Скрыть

Режим (mode):

Режим редактирования (edit mode)

Меню:

Curve ‣ Show/Hide

Горячая клавиша:

Alt-H, H, Shift-H

When in Edit Mode, you can hide and reveal elements from the display. You can only show or hide control points, as segments are always shown, unless all control points of the connected curve are hidden, in which case the curve is fully hidden.

See Отображать/Скрыть in Object Mode. See also the Curve Display panel.

Cleanup

Decimate Curve

Ссылка

Режим (mode):

Режим редактирования (edit mode)

Меню:

Curve ‣ Clean Up ‣ Decimate Curve

The Decimate Curve operator reduces the number of control points while trying to maintain the curves original shape. This operator works similar to its mesh counterpart.

Соотношение (сечение) (ratio)

The percentage of control points to remove.

Примечание

This tool can only decimate Bézier curves.

Удалить (delete)

Ссылка

Режим (mode):

Режим редактирования (edit mode)

Меню:

Curve ‣ Delete

Горячая клавиша:

X, Delete

Options for the Delete pop-up menu:

Вершины (vertices)

This will delete the selected control points, without breaking the curve (i.e. the adjacent points will be directly linked, joined, once the intermediary ones are deleted). Remember that NURBS order cannot be higher than its number of control points, so it might decrease when you delete some control point. Of course, when only one point remains, there is no more visible curve, and when all points are deleted, the curve itself is deleted.

Segment (сегмент)

Deletes the segment that connects the selected control points and disconnecting them.

Растворить вершины (dissolve vertices)

Режим (mode):

Режим редактирования (edit mode)

Меню:

Curve ‣ Delete ‣ Dissolve Vertices

Горячая клавиша:

Ctrl-X

Deletes the selected control points, while the remaining segment is fitted to the deleted curve by adjusting its handles.
