How Do I Make A Spiral In Inkscape?

You can make a spiral in Inkscape using the dedicated Spiral Tool, which provides interactive handles and an on-screen control bar for real-time customization. For more advanced effects, you can convert the spiral to a path and edit its individual nodes, or use extensions for more complex patterns.

1. The Inkscape Spiral Tool (Quick Method)

The simplest way to create and customize a spiral is by using the Spiral Tool directly.

Step 1: Select the Spiral Tool

• Click the spiral icon in the Toolbox, located on the left side of the window.
• Alternatively, press the F9 or I key on your keyboard.

Step 2: Draw the spiral

• To draw freely: Click and drag the mouse outwards on the canvas to draw a spiral.
• To constrain the rotation: Hold down the Ctrl key while dragging. This snaps the spiral's rotation to 15-degree increments.
• To reset to default: Click the Reset icon (a small broom) in the tool control bar at the top of the screen.

Step 3: Customize using the handles

After drawing, two diamond-shaped handles will appear at each end of the spiral. Switch back to the Spiral Tool (press F9) to see them.

• Outer handle:
  • Drag: Roll or unroll the spiral to increase or decrease the number of turns.
  • Shift + Drag: Scale and rotate the spiral at the same time.
  • Shift + Alt + Drag: Rotate the spiral without scaling it.
  • Alt + Drag: Increase or decrease the number of turns without changing the spiral's diameter.
• Inner handle:
  • Drag: Change the inner radius, making the spiral either wind more tightly towards the center or begin farther away from it.
  • Alt + Drag: Change the divergence. Dragging towards the center makes the turns tighter, while dragging away makes them looser and more uniform.
  • Shift + Click: Reset the inner handle to its default position at the center.

Step 4: Customize using the control bar

The tool control bar at the top of the screen allows for more precise adjustments using numerical inputs.

• Turns: Adjust the number of rotations.
• Divergence: Control the tightness or looseness of the spiral. A value of 1 creates a logarithmic spiral with uniform spacing, while values greater than 1 produce a more divergent spiral.
• Inner Radius: Set the fractional distance from the spiral's center to the beginning of the inner path.

2. Filling and styling a spiral

Because a standard spiral is an open path, it cannot be filled with color in the usual way.

Step 1: Add a fill

To fill a spiral, change the fill rule:

• Open the Fill and Stroke dialog by pressing Shift + Ctrl + F.
• In the Fill tab, change the fill rule from "Even-odd" to "Non-zero".

Step 2: Adjust stroke properties

• In the Fill and Stroke dialog, navigate to the Stroke style tab.
• Set the stroke width, style (e.g., solid, dashed), and add markers to the endpoints.
• The Stroke paint tab lets you set the stroke color, apply gradients, or use a pattern.

3. Converting to a path for advanced editing

To access and manipulate the individual nodes that make up the spiral, it must first be converted to a path.

Step 1: Convert the spiral

• Select the spiral with the Selector Tool (F1).
• Go to Path > Object to Path in the menu bar, or use the shortcut Shift + Ctrl + C.

Step 2: Edit with the Node Tool

• Switch to the Node Tool (F2).
• The individual nodes along the spiral's path will appear.
• Move nodes: Click and drag any of the square nodes to reshape the spiral.
• Adjust curves: Drag the circular handles attached to the nodes to change the curvature of the segments.
• Add nodes: Double-click anywhere on the path to add a new node.

4. Advanced techniques for creative effects

Create text on a spiral path

1. Draw a spiral with the Spiral Tool.
2. Type the text using the Text Tool.
3. Reverse the path if the text needs to start from the outside:
   • Select the spiral.
   • Go to Path > Object to Path.
   • Go to Path > Reverse.
4. Select both the text and the spiral.
5. Go to Text > Put on Path.

Create tiled or repeating spirals

• Tiled clones: This feature lets you create intricate, geometric patterns from a single spiral.
  • Select the spiral.
  • Go to Edit > Clone > Create Tiled Clones.
  • Experiment with the Shift and Rotation tabs to create complex, repeating spiral designs.

Create a whirl effect

• This extension distorts a selected path, twisting it into a vortex.
  • Draw and select a path (not a spiral). A simple circle or series of lines works well for a vortex.
  • Go to Extensions > Modify Path > Whirl.
  • Adjust the "Whirl Amount" to increase the intensity of the twisting effect. Higher values can cause jagged edges, which can be mitigated by first adding more nodes to the path.
