Use Pen to create precise SVG paths by placing anchors one at a time.
Click to place anchors. Hold Shift while placing an anchor to constrain the new segment to horizontal, vertical, or 45-degree diagonal angles. Press Escape after drawing a segment to commit the current path as an open path.
Use a tracing image as a visual guide when you need to manually draw an area boundary.
Open Pen paths are exported without fill. Closed Pen paths keep fill and can become bindable map areas.
