Abstract: Traction substation equipment in its life cycle has a large number of heterogeneous
information. However, when Autodesk Revit is used as modeling software to establish BIM model of
traction substation equipment, the model cannot meet the requirement of information integration for
the whole life cycle of the equipment due to the limited attribute parameter type and grouping mode.
Aimed at the above problems, this paper took traction transformer as an example, analysed the
non-geometric information of the traction transformer, then further classified and graded the
information, and finally proposed a new method which integrates the non-geometric information into
BIM model so as to combine both geometric and non-geometric information in the same Revit
document, and to facilitate the above methods, a plug-in module is developed using Revit API.
Experimental results have shown that the method can not only integrate the geometric information of
the equipment with a large number of non-geometric information in the same Revit document, but
also ensure the lightweight of the Revit document, and therefore achieve the desired objectives.

Key words: Revit, traction transformer, building information modeling, information integration
