Pen tools

Pen tools let you draw freeform shapes on the canvas. Unlike shape tools that create geometric primitives, pen tools give you control over every line and curve.

Freehand tool

Draw smooth, continuous curves by dragging across the canvas. The path is automatically smoothed as you draw.

How to use:

1. Select the Freehand tool from the toolbar
2. Click and hold to begin drawing
3. Drag to draw your shape
4. Release to complete the path

The Freehand tool creates filled shapes by default. Your strokes are converted into smooth bezier curves, so even quick drawings appear clean.

Connecting shapes

When you release near an existing line's endpoint, the shapes snap together and merge into one. This works with other Freehand or Polygon shapes. To close a shape, release near your starting point.

Polygon tool

Create shapes by clicking to place connected line segments. Use this when you need precise straight edges.

How to use:

1. Select the Polygon tool from the toolbar
2. Click to place the first point
3. Click to add additional points
4. Release near the starting point to close the shape, or near an existing shape's endpoint to connect

As you draw, a measurement guide shows the distance between your last two points.

Connecting shapes

Like the Freehand tool, the Polygon tool supports snapping. Release near an existing endpoint to connect shapes, or near your starting point to close the polygon.

Brush tool

Paint thick strokes with adjustable width. The Brush tool creates filled paths rather than thin lines.

How to use:

1. Select the Brush tool from the toolbar
2. Click and drag to paint
3. Release to complete the stroke

A circular cursor preview shows your brush size as you move over the canvas.

Brush sizes

Adjust the brush size from the context menu when the Brush tool is active:

Size	Description
Small	Thin strokes for detail work
Medium	Default size for general use
Large	Wide strokes for filling areas

Unlike the Freehand and Polygon tools, the Brush tool does not snap to other shapes.

Symmetry mode

All pen tools support symmetry mode. When symmetry is enabled, your strokes are mirrored across a center line, creating symmetrical designs automatically.

To enable symmetry mode, use the symmetry toggle in the toolbar.

Tips

• Zoom in for detail: Freehand and Brush strokes become more precise at higher zoom levels
• Use Polygon for angles: When you need sharp corners or straight edges, the Polygon tool gives cleaner results than Freehand
• Close shapes for 3D: Only closed shapes become solid 3D objects. Open paths appear as thin raised lines
• Undo strokes: Press Ctrl+Z (Cmd+Z on Mac) to undo your last stroke
