Контрольные точки (control points)#

Extrude Curve and Move#

Ссылка

Режим (mode):

Режим редактирования (edit mode)

Меню:

Контрольные точки ‣ Вытянуть кривую и переместить

Горячая клавиша:

E

Extrudes points by duplicating the selected points, which then can be moved, and connecting those points back to the original curve creating a continuous curve.

Make Segment#

Ссылка

Режим (mode):

Режим редактирования (edit mode)

Меню:

Контрольные точки ‣ Создать сегмент

Горячая клавиша:

F

Connects two disconnected control points. The selection must be loose points, or the first/last point of a curve, then press F. If the points belong to different curves, these are joined by a segment to become a single curve.

Two curves before.#

Curve after joining.#

Note that you can only join curves of the same type (i.e. Bézier with Bézier, NURBS with NURBS). Additionally, you can close a curve by toggling cyclic.

Наклон оси (tilt)#

Ссылка

Режим (mode):

Режим редактирования (edit mode)

Инструмент (tool):

Toolbar ‣ Tilt

Меню:

Control Points ‣ Tilt

Горячая клавиша:

Ctrl-T

This setting controls how the normals (visualized as arrows) twist around each control point – so it is only relevant with 3D curves! The tilt will be interpolated from point to point (you can check it with the normals).

30 degree Mean Tilt of all control points.#

Clear Tilt#

Режим (mode):

Режим редактирования (edit mode)

Меню:

Control Points ‣ Clear Tilt

Горячая клавиша:

Alt-T

You can also reset the tilt to its default value (i.e. perpendicular to the original curve plane). With NURBS, the tilt is always smoothly interpolated. However, with Bézier, you can choose the interpolation algorithm.

Set Handle Type#

Ссылка

Режим (mode):

Режим редактирования (edit mode)

Меню:

Контрольные точки ‣ Установить тип маркера (handle)

Горячая клавиша:

V

Handle types are a property of Bézier curves and can be used to alter features of the curve. For example, switching to Vector handles can be used to create curves with sharp corners. Read the Bézier curves page for more details.

Toggle Free/Align

Additionally, this operator can be used to toggle between Free and Aligned handle types.

Recalculate Handles#

Ссылка

Режим (mode):

Режим редактирования (edit mode)

Меню:

Control Points ‣ Recalculate Handles

Горячая клавиша:

Shift-N

The Recalculate Handles operator rotates the selected control point’s handle to be tangential to the curve. This can be used to make curves smoother and more consistent looking.

Длина (length)

Recalculates the length of the handles so they are all the same length.

Сглаживание (smooth)#

Ссылка

Режим (mode):

Режим редактирования (edit mode)

Меню:

Контрольные точки ‣ Сглаживание

For Bézier curves, this smoothing operation reduces the distance between the selected control point(s) and their neighbors, while keeping the neighbors anchored. Does not effect control point tangents.

../../../_images/modeling_curves_editing_control-points_smoothing-1.png

Original, unsmoothed Curve.#

../../../_images/modeling_curves_editing_control-points_smoothing-2.png

Entire curve smoothed over 20 times by holding Shift-R to repeat last step.#

../../../_images/modeling_curves_editing_control-points_smoothing-3.png

Only three control points in the center smoothed over 20 times.#

Smooth Curve Tilt#

Ссылка

Режим (mode):

Режим редактирования (edit mode)

Меню:

Контрольные точки ‣ Сгладить наклон кривой

The Smooth Curve Tilt operator interpolates the Tilt value for the selected control points. This will reduce sharp changes in the curve’s Tilt and give a smooth transition between points.

Smooth Curve Radius#

Ссылка

Режим (mode):

Режим редактирования (edit mode)

Меню:

Контрольные точки ‣ Сгладить радиус кривой

The Smooth Curve Radius operator interpolates the Radius value for the selected control points. This will reduce sharp changes in the curve’s Radius and give a smooth transition between points.

Smooth Curve Weight#

Ссылка

Режим (mode):

Режим редактирования (edit mode)

Меню:

Контрольные точки ‣ Сгладить вес кривой

The Smooth Curve Weight operator interpolates the Weight value for the selected control points. This will reduce sharp changes in the curve’s Weight and give a smooth transition between points.

Крюки (hooks)#

Ссылка

Режим (mode):

Режим редактирования (edit mode)

Меню:

Контрольные точки ‣ Крючки (Hooks)

Горячая клавиша:

Ctrl-H

Hooks can be added to control one or more points with other objects.

Создать родительскую вершину (make vertex parent)#

Ссылка

Режим (mode):

Режим редактирования (edit mode)

Меню:

Control Points ‣ Make Vertex Parent

Горячая клавиша:

Ctrl-P

You can make other selected objects children of one or three control points, as with mesh objects.

To select a mesh (that is in view) while editing a curve, Ctrl-P click on it. Select either one or three control points, then Ctrl-LMB the object and use Ctrl-P to make a vertex parent. Selecting three control points will make the child follow the median point between the three vertices. An alternative would be to use a Child Of constraint. See also the Curve modifier.
