--- layout: example.html title: Draw Shapes shortdesc: Using the ol/interaction/Draw to create regular shapes docs: > This demonstrates the use of the `geometryFunction` option for the `ol/interaction/Draw`. Select a shape type from the dropdown above to start drawing. To activate freehand drawing, hold the `Shift` key. Square drawing is achieved by using `type: 'Circle'` type with a `geometryFunction` that creates a 4-sided regular polygon instead of a circle. Box drawing uses `type: 'Circle'` with a `geometryFunction` that creates a box-shaped polygon instead of a circle. Star drawing uses a custom geometry function that converts a circle into a star using the center and radius provided by the draw interaction. tags: "draw, edit, freehand, vector" ---
