With a curve object in edit mode you will find some tools to edit the curve geometry in the tool shelf.

Tweak, Select, Transform, 3D Cursor Measure and Annotate tools

The tweak, select, transform, 3d cursor, measure and annotate tools at the end of the list are explained in the chapter 7.1.1 Editors - 3D View - Tool Shelf - Object Mode. We won't cover this tools again here.

Curve Stroke Panel

The curve stroke panel is covered in the chapter 25.1.1 Editors - Properties Editor - Tools Tab - Edit Mode. We won't cover this tools again here.

Draw

Allows you to draw a curve into the viewport.

Type

Type

Set the draw method for the curve. Poly draws a simple polygon shape. Bezier creates a Bezier curve type with handlers.

With type Bezier you will get more options.

Method

Method

The curve fitting method for a Bezier curve.

EntryWhat it does
RefitIncrementally refit the curve.
SplitSplit the curve until it fits.

Tolerance

Allow deviation for a smoother but less precise line.

Detect Corners

Detect Corners
Detect Corners

Detect corners and use non aligned angles.

Corner Angle

Corners above this angle are considered as corners.

EntryWhat it does
Taper Start / EndTaper factor for the radius of each curve point.
Radius Min/MaxMinimum or maximum radius when the pressure is applied.
Use PressureUse tablet pressure to draw the curve.

Depth

Depth

The method of projecting depth. Cursor or surface.

Cursor

Cursor has no further settings.

Surface
Project onto selected
Project onto selected

Projects the strokes only onto selected objects.

Absolute Offset

Apply a fixed offset, and don't scale by the radius.

Only First

Use the start of the stroke for the depth.

Plane

Plane

The plane for the projected strokes.

EntryWhat it does
Normal to SurfaceDraw in a plane perpendicular to the surface.
Tangent to SurfaceDraw in the surface plane.
ViewDraw in a plane that is aligned to the viewport.
EntryWhat it does

Curve Pen

Curve Pen

Extrudes start and end point of the spline to where you click with the mouse.

Tool Settings

Close Spline

Make the spline cyclic.

Extrude Handle Type
Extrude Handle Type

Type of the extrude handler.

Extrude Tools Group

Extrude Tools Group

This tools allows you to extrude out a new curve segment from the current selection

EntryWhat it does
SnappingHolding down Ctrl activates temporary global snapping.
Precision movementWhen you hold down shift, then you will have a much slower but also much preciser movement.

Header Values

Header Values

When you move your selection then you will see some values in the header, which defines the current position of the extrude point.

Move without Widget

You don't have to use the widget to move the object. You can also click aside of it, and drag the object around. The mouse turns into a move cursor. The standard behavior then is to move in screen space. When you want to move into a specific axis, then press X or Y or Z to limit the movement to this axis.

Limit Axis

Limit Axis
Limit Axis

When you want to move along a specific axis, then press X or Y or Z to limit the movement to this axis. You usually start in global orientation. But you can change this in the Orientation settings.

By holding down the mouse button and pressing the X, Y or Z key twice you can toggle this to local. But also to other orientations. This depends in what orientation you start. With normal you can toggle that way between Normal and Global.

Extrude

Extrude

The Extrude tool extrudes the current selection in the direction of the widget.

When you activate the tool, then you will by default see a yellow widget at the selection. Drag it to extrude the selection.

Header Value

Header Value

When you extrude curve points then you will see a value in the header. It tells you the current target position relative to the initial starting point(s) . This factor always starts with 0.

Tool Settings

Axis Type
Axis Type
Axis Type

You can choose between the regular axis type. That's the yellow widget with just one handler. It always points in the direction of the middled normals of the selection.

Or you can use the XYZ axis type. That's a handler with three axis. This widget can be aligned with the transform orientation methods.

When you click at the widget of the active tool, then you perform the tool action. Adjust what should happen when you click outside of the widget, in the empty area.

EntryWhat it does
Active ToolWhen you click off the widget then the click still does the same than clicking at the widget. It performs the active tool.
Tweak, Select Box, Circle and LassoWhen you choose this options then you will set the off click to the different select methods. Whereas tweak works more than a move tool then. Tweak is the default.

Proportional editing
Proportional editing

Enables proportional editing. Activating proportional editing reveals further settings.

Proportional SizeSee and adjust the falloff radius.
ConnectedThe proportional falloff gets calculated for connected parts only.
Projected(2D)The proportional falloff gets calculated in the screen space. Depth doesn't play a role. When it's in the radius, then it gets calculated.

Extrude Cursor

Extrude Cursor

Extrudes the control points to where you click.

Last Operator Add Vertex
Location X Y Z

The location of the new created control point(s).

Radius

Radius

Bezier curves have a radius. This is displayed by the black lines that points away from the curve. The radius tool allows you to resize this radius.

Header Value

Header Value

When you resize the curve radius then you will see a value in the header. It tells you the current scale factor. This factor always starts with 1.
