Electrical floor plan maker

In the floor plan editor of Avenler you draw walls, doors and windows, and rooms, or load an existing architectural plan as an underlay, then place switches, socket-outlets and luminaires and draw the cable routes. It runs in the browser, works floor by floor, prints on A4 or A3 sheets and can also save to DXF.

What is an electrical floor plan for?

An electrical floor plan is the electrical plan drawn on the building's floor plan: it shows where the switches, socket-outlets, luminaires or distribution board are, and where the associated cables run. The installer sees from it what has to be fitted where, and the client can check that every room has what they will need. The floor plan editor of Avenler creates it in the browser, floor by floor, and the program also calculates a bill of quantities and a quotation from the drawing.

How do you draw a floor plan in Avenler?

• Underlay. You can draw on top of an existing architectural plan: load an image (PNG, JPEG), a PDF (with page selection) or a DXF as an underlay. You set the scale by picking two points a known distance apart or by entering a value; wall drawing also snaps to the DXF's points. You can draw without an underlay too, typing wall lengths in centimetres.
• Walls, doors and windows, rooms. You draw walls as a chain (Shift = right angle); doors and windows are placed by clicking the nearest wall, and their width, height and position can be changed. The program also recognises enclosed wall areas as rooms and calculates their area.
• Devices. Symbols for switches, socket-outlets, luminaires, low-current devices, sensors, fixed connections and energy equipment. Wall-mounted symbols sit against the wall and can be rotated. You can browse the symbols on the electrical drawing symbols page.
• Room template. Places the usual layout in a room in one step: socket-outlets along the walls, a switch next to the door, a luminaire in the middle of the room. The values of the built-in templates (room, living room, kitchen, bathroom, hall) can be changed, and a modified template can be saved as your own. Templates are practical suggestions: the designer must review them.
• Cables and circuits. After you give two end points, the program plans the cable route along the walls and through doors; you assign devices to circuits, and colouring the drawing shows what has been left without a circuit.
• Multiple floors. Staircases and risers can be linked to their counterpart on another floor, and the rise between floors is included in the cable length. A floor can be copied, and it can also be taken over from another project.

Layers, dimensions, views

The Layers menu in the top bar switches the power, low-current and architectural base drawings separately, so several sheets can be produced from the same floor plan. Dimension lines are automatic (wall length, openings, the distance of devices from the wall) and can be changed by double-clicking: changing the value also moves the element. The wall elevation shows the wall surfaces of a room from the side, where devices can be dragged up and down along the wall. Real-size line drawings of sanitary ware and furniture can be added to help position the electrical items; these are not included in the take-off or the quotation.

Checks, printing, export

The Checks panel flags gaps while you draw (for example a device without a circuit, or a layout below the minimum counts that can be set for rooms), and clicking a finding jumps to the element. Printing is done on A4 or A3 sheets with a selectable scale and content, with a legend, circuit list, device designations and a title block. The PDF is saved from the browser's print dialog. A floor can also be saved to a DXF file (in mm, with devices as blocks by default), which CAD programs such as LibreCAD or QCAD can open.

What it cannot do

It loads a DXF as an underlay; there is no separate “walls from DXF” function: the walls have to be drawn. There is no mirroring on the floor plan. Room minimums, templates and checks are indicative only; they do not replace the professional responsibility of the electrical designer.
