Sym builds compositions out of polygons: place them, repeat them, style them, then export the result. Each tool below does one part of that, and the rest covers the canvas they all share.

Tools

Polygon

Drag shapes onto the canvas from the palette, snapping them edge to edge.

New Poly

Draw a polygon by clicking points on shapes already on the canvas.

Image Poly

Trace a reference image into image-backed polygons.

Clone

Repeat a shape around the canvas by picking two edges.

Style

Fill, outline and decorate shapes, and save styles you want to reuse.

Transform

Move, scale and rotate a selection, or snap it onto another edge.

Replace

Define a rule that swaps one shape for an arrangement of others.

Export

Frame the canvas and save it as a PNG or SVG.

Working with Sym

Layers

Separate a composition into layers with their own backgrounds and transforms.

Selection

Choose the shapes a tool acts on, then copy, extract or delete them.

Keyboard Shortcuts

Every key binding, from tool switching to undo.
