Start

What the editor does, and the fastest way in.

Short answer: drag symbols onto the plan, connect each switch to its lights, then save the layout or print it.

Plan where the outlets, switches and lights of a flat go, on top of the architect's drawing. Your plan file is read in this browser and never sent anywhere.

The electrical editor

One tab per storey of the plan.
Drag a symbol from the palette onto the drawing, or click it, then click the drawing.
Faint rings show where the rules suggest a symbol; let go near one and it snaps on.
Rings are suggestions only: they are not placed and do not print.
Connect: click a switch, then the lights it works; the page proposes the switch type.
Layout checks under the drawing: lights, switches, sockets, kitchen, smoke alarms, symbols outside rooms.
Keep your work as a layout file (Save or Copy layout); Open layout brings it back.

Quick start

Look at the example: the sample flat opens with one room planned.
Drag a symbol from the Symbols palette onto the drawing.
Connect: click a switch, then each light it works.
Keep your work: Save layout (or Copy layout).
Print view → ⌘P / Ctrl+P → Save as PDF.

How to

One tab per task: the steps first, the details folded below.

Drag a symbol from the Symbols palette onto the drawing; let go where it belongs.
Or click it in the palette, then click the drawing: picking alone places nothing.
Rings are suggestions: let go near one and the symbol snaps onto it.
Escape cancels a picked symbol; zoom and pan never move a placed one.

Symbol palette

The chosen set's symbols, grouped by category, each with its German and English name.
Drag one onto the drawing (mouse or finger).
Or click it (it stays marked), then click the drawing; Escape cancels.
The palette folds away with its title.

Placing a symbol

Drag and let go: the insertion point lands where you let go.
Or click the symbol in the palette, then click the drawing.
Picked is not placed: until you click the drawing, the rings are only suggestions.
Keyboard: Enter on the symbol, then Enter on the drawing places it mid-view.
Stored in drawing (model) coordinates: zoom and pan never move it.
The same position a DXF export will use.

Room of a symbol

Each placed symbol gets the id of its room from the plan file.
Inside a room's outline: that room.
Else the nearest label of a room without an outline, if close enough.
Else could not tell.
Shown when the symbol is selected; saved in the layout file.

room_label_max_m2 m
symbol_scale1 × nominal mm

Click a placed symbol to select it (dashed box); drag it to move it.
Rotate 90° (key R) turns it; a socket's stem points to its wall.
Delete (key Delete) removes the symbol or the selected link.
Undo / Redo (Ctrl/⌘ + Z) take any change back.

Select and move

Click a placed symbol to select it (dashed box); drag to move it.
Click the empty drawing to deselect.
Dragging the empty drawing pans the view.

Rotate 90°

Turns the selected symbol 90° counter-clockwise about its insertion point (key R).
A socket's stem points to the wall it sits on: rotate until it does.

Delete

Deletes the selected symbol with its links, or the selected link.
Keys: Delete or Backspace. Undo brings it back.

Undo / Redo

Undo takes back the last change: place, move, rotate, delete, connect, apply, open.
Redo does it again.
Keys: Ctrl/⌘ + Z and Ctrl/⌘ + Shift + Z.
The history is kept until the page is closed.

Click Connect: the switches are marked, everything else is dimmed.
Click a switch: what it may control turns green.
Click each light it works: a dashed link is drawn.
Escape or Connect again stops.

Connect (switch to light)

Connect turns Connect mode on or off; symbols do not move in it.
Switches are marked; everything else is dimmed.
Click a switch: what it may control is marked green.
Click each light it works: a dashed link is drawn on Elektro – Verbindungen.
A light it may not control is refused; the message names what it may control.
Another switch starts again; the same switch or Escape stops.

Links (Elektro – Verbindungen)

Dashed lines between switch and light insertion points: not cable routes.
Untick the layer to hide them on screen and in print.
Click a line to select it (thicker); Delete removes it, Undo brings it back.
Deleting a symbol deletes its links too.

Switching groups (under the drawing) lists the lights that share switches.
The page proposes the type: 1 Ausschaltung, 2 Wechselschaltung, 3+ Kreuzschaltung.
Apply swaps the placed switches to the proposal; nothing changes without it.

Switching groups and the proposed switch type

A group is a set of lights sharing switches (joined by links).
1 switch: Ausschaltung (one-way switch).
2 switches: Wechselschaltung (two two-way switches).
3 or more: Kreuzschaltung (two two-way switches, an intermediate switch per extra place).
With a push-button: no proposal (impulse relay or timer: the Elektroplaner decides).
Only shown: nothing changes until you click Apply.
The textbook rule: the actual wiring is for the Elektroplaner.

Apply the proposal

Swaps this group's switch symbols to the proposed codes.
Positions, rooms and links stay.
One click, one Undo step.

While you pick, drag or move a symbol, rings show the suggested spots.
The ring it will snap to turns yellow; let go near it.
Untick Snap, or hold Alt/Option, to place freely.
Rules picks the values: starting values (to confirm) or the Elektroplaner's.
Layout checks under the drawing say what is ok, to look at or could not tell.

Placement suggestions (faint rings)not printed

Rings show where the chosen rule set suggests that kind of symbol.
Shown while you pick, place or move a symbol; the room under the pointer is brighter.
The ring it would snap to is yellow; rings keep their size at every zoom.
Rings are not symbols: they are never saved or printed.
Hover a ring for its rule.
Switches: beside each door, on the room side, opposite the hinge.
Sockets: the middle of each wall piece between doors. Ceiling lights: the room centre.
Kitchen outlets: along the walls of rooms whose label marks a kitchen.
Could not tell: no walls without a room outline; no switch where the door swing is unknown.
Windows from the plan: socket and kitchen rings keep clear by window_margin_m.
Older plan file (windows unknown): a ring may fall in a window niche.
No rule for wall lights and the other symbols.

From the placement rules (presets/el_parameters.json).

H1 Lights with no switch

Every light no link reaches.
Could not tell when no light is placed.

H2 Switches with no light

Every switch or push-button without a link.
Could not tell when no switch is placed.

H3 Doors without a switch

Every room with a light: each door needs a switch within hint_switch_near_door_m of its opening.
Could not tell: no value in the rule set, a light's room unknown, no door, or no rooms.

H4 Rooms without a light

Rooms of the types in check_light_room_types need a light.
Room type from the label words; wet rooms from the plan.
Could not tell: a room whose type no label word gives.

H5 Too few sockets

Socket outlets per room at least check_min_sockets_<type>.
A double socket counts two.

Sockets near a shower or bath must keep out of its zones.
The plan knows no zones: always could not tell; ask the Elektroplaner.

H9 Symbols outside every room

A symbol whose room could not be told.
Could not tell: move it into a room, or check the plan's room outlines.

Files

The three file kinds the page reads and writes, field by field.

Layout file format

JSON, described by schema/el_layout.schema.json (fields below).
Positions in model (drawing) units; rotation in degrees counter-clockwise.
links: which switch works which light; rule_set: the placement rule set chosen.
Version 2; a version-1 file still opens, with no links and the default rule set.

From schema/el_layout.schema.json.

Field	Type	Required	What it is

schema	= "el_layout"	yes	Always el_layout: says what kind of file this is.
schema_version	one of 1, 2	yes	Version of this format: 2 (switch-light links, rule set). Files of version 1 still open: they are migrated to 2 with no links and the default rule set; a version-1 file with links is refused.

About

Privacy, what is new, how it is built.

One self-contained page: no server, no analytics, nothing loaded from other sites.
Files you open or paste are read by this browser only.
Drafts stay in this browser's storage.
tools/export_plan.py runs on your computer and writes the plan file there.
The plan file holds the DXF's name and checksum, not its folder.

06.10.2026 · Parameters is a page tab

Parameters sits beside Editor and Documentation, so the storey never disappears.
Editor brings the storey back exactly as it was: tab, zoom, layers, selection.

05.10.2026 · Windows, layout checks, CAD export

Windows read from the drawing: socket and kitchen rings keep clear of them.
Layout checks H1-H9 with counts: lights, sockets, kitchen, smoke alarms.
DXF export (on your computer): the layout as Elektro layers for the Elektroplaner.

04.10.2026 · Shorter documentation, readable parameters, honest print view

Documentation in tabs, with short bullets and folded details.
Parameters in one readable table per group; Live or Needs re-export explained once.
Print view warns when a symbol is picked but not placed: rings never print.

04.10.2026 · The editor in the toolkit

Open plan: your own drawing, exported on your computer by tools/export_plan.py.
Synthetic sample flat with the simple example (Wechselschaltung in the Wohnzimmer).
Paste a plan, layout or parameter file anywhere on the page.
Light and dark page theme; the drawing stage stays black.

One code base: tools/build_editor.py builds the page.
Every text comes from presets/editor_docs.json; every value from presets/el_*.json.
Gates: short popups, short Documentation text, no dangling link.
