Transform

Reference

Mode:

編輯模式

選單:

Curves ‣ Transform

A curves objects can be edited by transforming the locations of control points.

Move, Rotate, Scale

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

To Sphere, Shear, Bend, Push/Pull

The transform tools are described in the Transformations sections.

Radius

Tool:

Toolbar ‣ Radius

選單:

Curves ‣ Transform ‣ Radius

Shortcut:

Alt-S

The Radius allows you to directly control 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.

Duplicate

Mode:

編輯模式

選單:

Curves ‣ Duplicate

Shortcut:

Shift-D

This operator 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.

Delete

Mode:

選單:

Curves ‣ Delete

Shortcut:

X

The Delete operator can remove Control Points or Segments. Deleting can be used to make curves shorter or simplify segments by deleting control points in the mid section of a segment.

Toggle Cyclic

選單:

Curve ‣ Toggle Cyclic

Shortcut:

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 Curve Type

選單:

Curves ‣ Set Curve 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).

Handles

Take handle information into account in the conversion
