A method for digitally modeling an industrial space, the industrial space including a plurality of pieces of equipment (E3) disposed in an industrial building (B), the modeling method including a step of three-dimensionally digitizing the industrial space so as to obtain a web (NAP) defining meshes representing the outer envelope of the industrial space with all of its pieces of equipment (E3), a step of real-time segmenting the web (NAP) in a virtual environment by a user during which: a bounding box (F) is positioned to bound at least one piece of equipment to be segmented (E3), and the points of the web (NAP), belonging to the volume of the bounding box (F), are associated so as to form a virtual object (OBJ).
