Edit Tool

Top  Previous  Next

 

 

The Edit tool is used to modify previously created shapes and curves.  It can be selected from the Canvas toolbox.

 

 

 

Workspace

 

The Edit tool provides access to the control points defining a curve.  For details on how control points influence a curve's shape, please refer to Understanding Curves.

 

 

Edit Tool 1 b

Select a curve shape to reveal its handles, which can

be modified as described in Understand Curves.

 

Edit Tool 3

If the selected shape isn't revealing the

desired curve handles, click Convert.

 

Edit Tool 2

If there isn't a control point at the desired location, click the

desired location to add a temporary point, then click Add to

add a new control point, or click Split to divide the curve.

 

Edit Tool 4

Alter control point behavior by switching it

between Corner, Smooth, and Cusp modes.

Edit Tool 5

Select multiple control points simultaneously by

either holding down shift while clicking them, or

by dragging a selection marquee over them.

 

 

 

 

Stroke Section

 

If the selection contains at least one open curve, this section will appear with a single slider that modifies the width of the stroke applied to the selected open curves.

 

 

 

Convert to Curves Section

 

This section appears in the Edit tool ribbon if the selection is a preset shape.  You can gain finer control over the shape by clicking the Convert button.

 

 

 

Curve Section

 

This section will only appear in certain circumstances, as described in the following table.

 

 

Option

Description

Separate

This button appears if the selected curve consists of disconnected parts.  Clicking it separates the disconnected parts into different curve shapes.

Merge

This button appears if multiple curve shapes are selected.  Clicking it merges the curves into a single shape.

 

 

 

Optimize Section

 

This section appears if a curve is selected.

 

 

Option

Description

Optimize

Reduces the number of control points used to define the selected curve.  If clicking this button has no effect, try increasing the Strength slider below.

Strength

Specifies how aggressive the optimize function will be in reducing the number of control points used by the curve.  Higher values will result in fewer control points being used, at the cost of detail.

 

 

 

Control Point Section

 

This section appears when one or more control points are selected.

 

 

Option

Description

Add

This button appears if you have created a temporary point by clicking an arbitrary point on the curve.  Clicking this button converts the temporary point into a control point.

Delete

This button appears if one or more control points are selected.  Clicking it removes the control point(s), which will usually result in a reduction of curve detail.

Split

This button appears if either a temporary point or a single control point is selected.  Clicking the button cuts the curve at the selected point.

Join

This button appears if two end points are selected.  Clicking it closes the gap between the selected points by merging them into a single control point.

Corner

This button appears if one or more control points are selected.  Clicking it causes the curve to form sharp corners at the selected points, as shown in the following illustration.

Smooth

This button appears if one or more control points are selected, but no end points are selected.  Clicking it causes the curve to move smoothly through the control points, as shown in the following illustration.

Cusp

This button appears if one or more control points are selected.  Clicking it allows tangent points to be freely moved, as shown in the following illustration.

Location sliders

These controls appear if exactly one control point is selected.  They provide numeric control over the point's location.

 

 

Control Point Modes

Corner mode: Tangent points automatically point towards neighboring control points.

Smooth mode: Tangent points always point away from each other.

Cusp mode: Tangent points are free to move in any way.

 

 

 

Tangent Point Section

 

This section appears when exactly one control point is selected, and in addition one of the tangent points belonging to the control point is also selected.

 

 

Value

Description

Tangent Location Sliders

The two location sliders control the position of the tangent point.  The position is expressed relative to the location of the control point that the tangent point belongs to.

Tangent Length Slider

The length slider controls the distance between the selected control point and tangent point.

Tangent Angle Slider

This slider controls the angle of the selected tangent line.

 

 

 

Shape Controls/Stroke Section

 

If a preset shape is selected, a Shape Controls section may appear in the ribbon as it does for the Shape tool.

 

If an open curve is selected, a Stroke section will appear in the ribbon as it does for the Draw tool.  However, while the Draw tool doesn't allow multiple shapes to be selected simultaneously, the Edit tool does.  This means that the Edit tool can be used to change the widths of multiple curves simultaneously.  More on multiple selections is available here.
