Which building cabling software to choose?


On the market for technical software for the building industry, there are various CAD cabling software packages for the various functions required:

  • Drawing / integration of the architect’s plan
  • Layout plan with devices, boxes and panels
  • Wiring plan with cable routing and lengths
  • Single line diagram / multi-line diagram of the different circuits
  • Verification and standardised calculation of protection and cable sections
  • Layout of electrical cabinets
  • Interfacing with BIM models

Publishers provide products of different levels, from basic to very sophisticated and even complex.

Some functions are also developed by the component manufacturers.

To make a choice of cabling software, it is necessary to check certain points:

  • Functional points
  • Ergonomic points
  • Professional context of the supplier

Functional points of the cabling software

The architectural plan
  • The architect’s drawing can be integrated in DWG or PDF format
  • The architect’s plan can be drawn (in case there is no architect’s plan)
The devices
  • The installation of the devices must be quick with location and advanced placement functions
  • Devices can be identified on the architect’s drawing (devices placed by the engineer and to avoid re-keying)
  • The creation of new devices should be simple
  • The software must include a graphic legend
  • The BOM output must be configurable and associated with the plan
  • The plan should include tables and circuits
  • The symbols must be associated with components
  • The cabling functions must allow for continuous star cabling
  • The software must extract the lengths and routing of the cables (tertiary)
  • The cable trays must be dimensionable
  • The software must handle both high current (light, plug) and low current (intrusion, home automation, IT, etc.)
  • The choice of wires and sheaths must be automated (housing)
  • The labels must be issued automatically and be configurable
  • a 3D view must allow the elevations to be visualised
  • The schematic functions are advanced (connection, disconnection, copy/paste)
  • The schematic functions allow the creation of single and multi-line diagrams
  • Single line diagrams can be automatically output and linked to the plan
  • Schematics can integrate control and automation pages
  • Terminal blocks are generated automatically
Electrical cabinet
  • The electrical panel is defined from the circuits
  • It can be defined with components from different suppliers
  • The calculation must propose the protections adapted to the standard
  • The calculation must propose the cable cross-sections adapted to the standard
  • It must be interactive with the wiring diagram
  • It must produce the various forms for certification
  • The software must read a BIM model and reinject the component information

Points on the ergonomics of the layout and cabling software

  • The product must be flexible and accessible
  • Functions should be easily customisable for symbols, cartridges, component database, schematic, cabinet volumes
  • The number of training days should be reasonable, around 3 days (too many days often means complexity of handling)

Professional background of the supplier of the layout and cabling software

  • The company must be as sustainable as the product
  • The maintenance service must be local, not off-shore or sub-contracted
  • The support service must be concrete, with real assistance and good reactivity
  • Training must be carried out by specialists


The choice of a CAD product for layout or wiring corresponds to the desired automated functions. The product should therefore preferably be modular.

A detailed presentation, lasting about an hour, will allow you to form a relatively complete opinion of the software presented.

This presentation will help you find the right product for your business, with advanced features, quality service and an affordable price.
