Drawing and Sketch

Sketch with the Freehand pen, snap rough sketches into real shapes with the Shape Pen, and place point-by-point polygons.

Sometimes the fastest way to capture an idea is to draw it. The palette's Draw category holds the drawing tools: Freehand for smooth strokes kept exactly as drawn, the Shape Pen for rough sketches that snap to real shapes, and the Polygon tool for clean point-by-point outlines (plus Arrow, covered in its own guide). Everything they draw is a regular element you can move, resize, and style.

Looking for the marker? The Highlighter is a canvas mode now, not a draw tool: see Highlighter.

Freehand and the Shape Pen

Both pens are gestural tools: pick one from the palette's Draw category (Freehand is P, Shape Pen is 6) and the next drag on the canvas draws a stroke. A small mode banner tells you which pen is armed, with a Cancel action, and the cursor swaps to a pen icon so you know you are in draw mode.

The only difference is what happens on release: Freehand keeps the stroke exactly as you drew it, and the Shape Pen matches it against real shapes.

Select Freehand or the Shape Pen from the palette's Draw category.
Drag across the canvas to draw. A live preview follows your pointer.

Release to commit the stroke. A stray click with no drag does not create anything.

On release, your raw points are smoothed into a clean, hand-drawn curve rather than a jagged polyline. If you release near where you started, the path closes into a custom shape and fills, which is the way to sketch a bespoke outline.

Styling a sketch

A committed sketch is a regular boxed element. Its stroke colour follows the tab's theme so it reads as part of the diagram rather than a separate annotation layer, and a closed path fills with the theme's fill colour. From there you can:

  • Move it, resize it (the path scales proportionally), and lock or group it.
  • Recolour its stroke and fill from the element's Colours controls.
  • Apply the format painter, themes, and comments, exactly as with any shape.

The Polygon tool

The Polygon tool fills the gap between freehand sketching and the fixed shapes: clean, straight-edged outlines with exactly the corners you choose, for zones on an architecture diagram, floor plans, or any irregular region.

Select the Polygon tool from the Draw category.

Click to place each point. A preview line follows your pointer from the last point you placed.

Click the start point (a snap ring appears when you are close) to close the outline into a filled polygon, or double-click (or press Enter) to finish an open line at the last point.

Placing polygon points click by click, with the snap ring on the start point ready to close the outline.

While placing points, Backspace removes the last point so you can walk a mistake back without starting over, and Escape clears the in-progress outline. A closed polygon fills with the theme's fill colour like any closed sketch; an open line stays stroke-only.

Shape recognition

Pick the Shape Pen instead of Freehand and your sketches are matched against real shapes on commit. A rough square becomes a square, a loop becomes a circle, and a straight stroke becomes an arrow. See Shape recognition for the details and which kinds are detected.

Drawn with the Shape Pen, a rough sketch snaps into a clean shape on commit.

Nothing is remembered between strokes: Freehand always keeps what you drew and the Shape Pen always tries to convert it, so a stroke never behaves differently from the last one for reasons you cannot see.
