How to tie connections into a bundle on the canvas?

When many parallel connections run between two columns of blocks, they pile up into a tangle. A wire tie gathers them into a tidy bundle with clamps. Only the drawing changes: scenario logic, validation and execution stay exactly the same.

When you need it

Several long connections run from one part of the scenario to another and cross the whole canvas.
You want one connection to go around a block without moving blocks.
You want the diagram readable before you show it to a colleague.

What you need to know

An administrator turns the wire tie on: Menu -> Settings -> Instance settings -> Feature flags -> Scenario Builder -> "Wire ties". While the flag is off, connections are drawn straight, and saved ties are not erased.
All strands have one color. To see where a connection goes, hover its tail: the whole connection is highlighted.
A single connection with a bend point is the same tie with one clamp.
A tie can have up to 8 clamps.
Clamps do not move when you move blocks by hand. Fix them by dragging, or run auto layout: it moves ties together with the blocks.
Auto layout started by the AI agent does not move clamps.
Scenario Builder has no undo.
If a colleague is editing the section, you see their ties but cannot change them.
On Linux the window manager sometimes takes the Alt key. Use the "Wire tie" button on the toolbar instead.
If the platform is rolled back to an older version, ties disappear from the sections you publish from it. Scenario logic is not affected.

Before you start

You are in the Scenario Builder editor with editing rights.
The section is open for editing (not held by a colleague).
An administrator has turned on "Wire ties".

Step by step

1. Tie several connections

Hold Alt (Option on a Mac). The cursor becomes a crosshair and a hint appears at the bottom.
Press the left mouse button on an empty spot of the canvas or on a connection and draw a line across the connections you want. Next to the cursor you see what will happen: "Tie connections: N".
Release the button. The connections gather into a bundle with one clamp.

Without a keyboard, for example on a trackpad: press the "Wire tie" button on the toolbar and draw the line without Alt. After a successful line the mode turns off. Esc cancels the line, another Esc leaves the mode.

2. Add a bend point to one connection

Draw a line across one connection: next to the cursor you see "Add a bend point". The connection then passes through the new point in a smooth curve.

3. Move a clamp

Drag a clamp (or a bend point). The connections follow it.

4. Add another clamp

Hold Alt and drag a clamp: a new point appears next to it and you carry exactly that one. This way a bundle can go around blocks.

5. Remove a clamp

Double-click the clamp. When the last one is removed, the tie disappears.

6. Remove the tie

Click any tied connection, on its tail or on the part between the clamps. The whole tie is highlighted, not a single connection. Press Delete or Backspace: only the tie is removed, the connections go straight again and are not deleted. To delete a single connection, remove the tie first.

What happens next

The tie is saved with the section when you publish, and goes into import and versions. Export carries ties only when the new export format is enabled on the instance; otherwise the file holds the connections without ties, and they come out straight after import. If you need ties in an export, ask the platform administrator to check this format. Cloned blocks and blocks copied to another section arrive without a tie.

How to check that it worked

Connections run as one bundle, and a gray strip is visible between the clamps.
After you publish and refresh the page, the bundle is in place.
Hovering a tail highlights the whole connection.
