KNOWLEDGE-BASED MODELLING FOR AUTOMATIZING HBIM OBJECTS. THE VAULTED CEILINGS OF PALAZZO DUCALE IN URBINO

Description

Vault modelling in HBIM poses a significant challenge due to the geometrical complexity and lack of standardization of those elements. Starting from the definition of an ontology able to describe and manage different typologies of Italian Renaissance vaults, this paper presents two methods for their representation in the context of Ducal Palace of Urbino HBIM implementation. The first method is a simplified semi-automated scan-to-BIM procedure relying on Revit adaptive families; the second is a more complex parametric scripting in Dynamo VPL. The paper proposes a library of suitable vault families for the parametric modelling of Renaissance architecture and offers a comparison between the models generated and their respective surveyed point-clouds, with the aim of assessing the procedure. Revit adaptive families appeared to be the easiest to implement and the most efficient solution, while Dynamo allowed for greatest complexity thought showing limitations and implementation difficulties.
