For infrastructure crews · centimetre-accurate stake-out

Know exactly where to build.

Arlens is a phone app with a clip-on RTK antenna. It brings all your 3D models into one place, then sets them out on site to the centimetre — so you build in the right spot, the first time.

How it works

From your models to the ground, in three steps

No more guessing off 2D drawings, or waiting on a surveyor to stake it out.

  1. 1

    Add your models

    Drop your DXF, DWG, IFC and XML files in — every model in one place.

  2. 2

    View and plan

    Open every model on your phone and see exactly what goes where — before you start.

  3. 3

    Set out on site

    Clip on the RTK antenna and place each model exactly where it belongs — to the centimetre.
