Use Polylines and Connectors to Explain a Map
Draw guided walking paths, transit corridors, directional arrows, and leader line callouts that keep complex maps organized and easy to navigate.

When and why to use vector line overlays
While markers pinpoint spots and shapes define rooms, lines tell stories of movement and connection. They guide visitors along physical pathways, explain emergency evacuation routes, showcase campus tour sequences, and illustrate infrastructure runs.
Layerpin provides three specialized vector line types: Polylines (multi-segment connected vertices for paths), Curved & Straight Connectors (for leader line callouts), and Directional Arrows (for one-way traffic, entrances, and flow).
- 1Use Polylines for multi-turn paths, hiking routes, and walking corridors.
- 2Use Directional Arrows for flow control (e.g., parade routes, vehicle drop-offs).
- 3Use Callout Connectors to link text labels cleanly to tight, crowded map points.
Drawing and editing smooth multi-point paths
Drawing polylines in Layerpin is intuitive and non-destructive. Click along your map background to drop vertex waypoints following hallways, sidewalks, or roads. Double-click to complete the line.
Need to adjust a turn later? Select the polyline to reveal interactive vertex handles. Drag any point to shift its position, or click the midpoint plus handles to insert new vertices on the fly without redrawing.
Customize stroke width (from thin 2px reference lines to bold 6px highlighted routes), line caps, join styles, and dash patterns (solid, dashed, dotted).
- 1Click to place sequential path points and double-click to finish.
- 2Use midpoint handles to add turns or adjustments without starting over.
- 3Choose dashed styling for secondary or seasonal routes to contrast with primary paths.
Using Callout Connectors to declutter dense areas
On high-density maps-such as a medical campus with 30 clinics clustered in one wing, or a microchip technical diagram-placing markers and titles directly over coordinates creates an illegible tangle of overlapping text.
Callout Connectors solve this by anchoring a leader pin at the exact physical feature, while allowing the text badge and info trigger to sit comfortably in adjacent open canvas space.
The connector line automatically tracks and maintains its link if either the anchor pin or the callout badge is moved, ensuring pristine layout alignment at all times.
