# Topology

Category: Documenting sites. Updated 2026-11-12.

The topology map draws a client's network from the internet down — every device beneath what it links to, with the runs between them — and can be narrowed, rearranged, saved as a named view, and downloaded.

## Open the map

Press **Topology map** on a client's page to draw the whole client, or on a property's page to start with that property. The **Show** list at the top switches between **Whole client** and one property at a time.

## Read the map

- Each device is a box under the device it connects up to. Links are drawn in the colour of what they are made of, and the **Legend** under the map keys every colour in use.
- Rest the pointer on a device, or focus it, to see its facts in a card.
- Tap a device to open its details: beside the map on a desktop, or in a sheet on a phone. **Open device** in the details goes to the device's page.
- The line under the map counts the devices and links drawn, and says how many were left out by filters or lead outside the rooms shown.
- **Fit** (beside **Hide panels** on a desktop, at the head of the map's tools on a phone) draws the whole map inside the frame, both ways. It never shrinks the map below a size you can read (the frame scrolls instead, opening on the top of the hierarchy) and enlarges a small map only so far. **Actual size** draws it at its own size.
- The devices of each room are boxed together, and the room's name sits at the box's head, or at its foot when lines cross the head.
- Two devices joined by more than one link are drawn with one line, its words ending **+ 1 more** (or however many run beside it).

## Choose a view

**View** switches how the same devices are drawn:

- **Topology**: the network as it is cabled, each link in the colour of its medium.
- **Wiring**: each run coloured by its cable type — a wiring map.
- **Signal flow**: each link drawn by the signal it carries (video, audio, control, network), as an AV diagram reads.
- **Layer 3**: the subnets as lanes, each device in the one its address falls in.

## Narrow the map

- **Rooms**: draw only the devices in the rooms you tick.
- **Links**: draw only the kinds of link you tick.
- **Runs**: draw only active or spare runs.

Leave a filter empty to draw everything of its kind. Each filter in use shows as a chip with its own remove button, and **Clear all** removes them all.

**Pass through patch panels** hides the panels and draws each run behind them as one link, with the lengths added up.

## Rearrange the map

Drag a device to move it where it reads best (every view but **Layer 3**, which places devices by subnet). **Reset layout** puts every device back where the automatic layout drew it. To keep your arrangement, save it as a view.

## Save a view

1. Set up the scope, filters, and layout you want.
2. Press **Save as view**, type a **View name**, and press **Save view**.
3. Later, choose it in **Saved view** to draw the map that way again. The view has its own address, so you can bookmark it.

With a saved view chosen, **Update view** saves your changes to it and **Delete view** removes it.

## Download the map

Under the map:

- **Download SVG**: a drawing you can edit.
- **Download PNG**: a picture to share.
- **Download draw.io**: a file to open and rework in draw.io.

The topology map is also drawn inside the client and property reports. See [Reports and sharing](https://cablefolio.com/help/reports-and-sharing/).

## On a phone

A map wider than the screen scrolls sideways. The filters and views sit above the map rather than beside it, and a tapped device's details open in a sheet. On a desktop, **Hide panels** (or `Ctrl+H`) gives the map the full width.
