Drawing

The Shape menu: flip, mirror, scale and align

Flip, mirror, rotate, scale, align, split, smooth and proportion guides.

Updated 11 October 2026

Most commands work on the selected shapes. Commands that ask for numbers open a small dialog; Reset values clears them.

Arranging and transforming

Command Key What it does
Group / Ungroup Ctrl+G / Ctrl+U See Grouping.
Flip horizontally / vertically Ctrl+I / Ctrl+J Mirror the selection about its own centre.
Symmetry Ctrl+L Click a line: the selection is mirrored across it as a copy (the line itself isn't copied).
Rotate ▸ 1° / 5° either way [ ] { } Rotate about the selection's centre, or the rotation/scaling centre you set.
Rotate ▸ Rotate by angle… – Any angle, clockwise.
Scale ▸ Enlarge/Reduce 1% / 5% – Scale steps.
Scale ▸ Scale by ratio… – A ratio from 10% to 1000% (0.1× to 10×). The dialog shows the range and won't apply a value outside it.
Scale ▸ Scale horizontally only… / vertically only… – Stretch one way (circles become ovals), by a ratio in the same range.
Align ▸ left, right, top, bottom, centres Ctrl+Alt+L/R/T/B, Ctrl+Alt+Shift+H/V Align to the selection's edges. On a Mac these use the Control key.
Arrange ▸ Bring to front / Send to back – Change which shapes are drawn on top.
Lock / Unlock all – See Locking.
Move or copy by distance… Ctrl+Shift+C Move the selection by X and Y; tick Keep the originals and make a copy to copy it.
Make the line horizontal / vertical – Click a line: the whole selection turns so that line is level or plumb.
Reverse path direction Ctrl+F Reverses which way lines, curves and arcs run. Matters for stitching order and export.

Geometry edits

Command Key What it does
Extend or trim two lines to meet Z Two lines meet exactly at their crossing.
Split at intersections – Cut the selected shapes wherever they cross.
Split into N… – Cut a line, curve or arc into N equal pieces.
Specify size by number… – Set line length, circle diameter, arc radius and sweep for all selected shapes.
Set the angle between two lines… – Two lines joined at an end: type the angle they should make.
Tidy connected lines – Trims the overhangs where lines of one type cross near their ends, so they close up ("Trimmed to a closed shape.").

Template objects

A template object is one shape made of many lines and curves; its closed parts are drawn filled. Useful for logos, hardware outlines and repeated parts.

Command Key What it does
Convert to template object F9 Replace the selection with one template object.
Convert a copy to template object F10 The same, keeping the originals.
Separate template into shapes F8 Turn a template back into lines and curves.
Register as library template… – See Template library.

Curves

Command What it does
Convert arc to Bézier curve Replace arcs with equivalent Bézier curves.
Smooth connected Bézier curves ▸ Tangent continuity (G1) Joined curves leave each joint in the same direction.
Smooth connected Bézier curves ▸ Curvature continuity (G2) Also match how tightly they bend at each joint.

Both smoothing commands are also on a Bézier curve's right-click menu.

Design guides

Command What it does
Draw boundary… A rectangle round the selection, with a margin.
Golden ratio guide / Silver ratio guide Proportion guides from a short side you enter.
Draw golden spiral A golden spiral in the selected arc's box (also on the arc's right-click menu).
