A complete documentation and conservation of a historic timber roof requires the integration of geometry modelling,
attributional and dynamic information management and results of structural analysis. Recently developed as-built Building Information
Modelling (BIM) technique has the potential to provide a uniform platform, which provides possibility to integrate the traditional
geometry modelling, parametric elements management and structural analysis together.
The main objective of the project presented in this paper is to develop a parametric modelling tool for a timber roof structure whose
elements are leaning and crossing beam frame. Since Autodesk Revit, as the typical BIM software, provides the platform for parametric
modelling and information management, an API plugin, able to automatically create the parametric beam elements and link them
together with strict relationship, was developed. The plugin under development is introduced in the paper, which can obtain the
parametric beam model via Autodesk Revit API from total station points and terrestrial laser scanning data. The results show the
potential of automatizing the parametric modelling by interactive API development in BIM environment. It also integrates the separate
data processing and different platforms into the uniform Revit software.
