How to draw a line
Select the Line tool from the toolbar. The context panel shows a Stroke Width slider.
Set stroke width (1-50 px). This controls the thickness of the line.
Choose a colour from the colour picker. The line is drawn in your currently selected colour.
Click the start point and hold your pointer down on the canvas.
Drag to the end point. A live preview appears as you drag. Hold Shift to constrain to 0°, 45°, or 90°.
Release to draw the final line permanently onto the canvas.
Line features
Angle constraint
Hold Shift while dragging to snap to 0°, 45°, or 90° angles — essential for geometric diagrams and grids.
Live preview
See the line before you commit — adjust your aim before releasing.
Any thickness
Lines from 1 px hairlines to 50 px bold rules. Each line is a separate history entry.
Tips
Hold Shift to draw perfectly horizontal, vertical, or diagonal (45°) lines without a ruler.
Use stroke width 8-15 px to create bold borders and frames for your artwork.
Combine multiple lines to create custom shapes, stars, and patterns beyond the preset shapes.
