Arrows & connectors

Connecting two elements

Press C (Arrow tool), then drag from one element to another. As you approach an element, its anchor point lights up and the arrow end snaps magnetically to it. Release, and the connection is permanent: move either element and the arrow follows.

Ends that attach to nothing

An arrow end does not have to land on something. The magnet only reaches about 15 px, so an end released further away from every element simply stays where you dropped it — for pointing at a spot, labelling an area, or sketching a connection before the other half exists. The same goes for where an arrow starts: begin the drag on empty canvas and the arrow starts there.

The white dots that appear while you drag show what an arrow could attach to; the dot only turns black and grows once you are close enough that releasing will actually attach. A free end can be picked up and dropped onto an element later — and dragged off it again.

Editing an arrow

Click an arrow to select it:

• Re-route: drag either endpoint to a different element — or onto open canvas to detach it.
• Bend: drag the midpoint handle to bow the arrow into a smooth curve — essential when several arrows share a path. A single click on the bend handle straightens it again.
• Style via the floating bar: line color (palette + custom), start and end caps — none, arrow, dot or square — and stroke width from 0.5 to 8.
• Delete with Delete or the bar’s trash button.

Several arrows can attach to the same element — even the same anchor. With caps on both ends (or none) an arrow becomes a relationship line rather than a direction.

Arrows vs. lines

Arrows can attach — and the ends that do follow their element around. The line shape never attaches, but is a real element in return: it can be selected, moved, grouped and stacked like any other. Rule of thumb: relationships between things → arrow; a visual separator or underline you want to move around → line.
