Methodology for creating 3D paper unfolded models with complex geometry using open-source software and resources with free personal and commercial license

Abstract

The creation of 3D paper unfolded models with complex geometry requires precision in the design process. Achieving this is through the use of accessible resources and modern technological means which possess the necessary technical and functional capabilities. The successful realization of the models is through the use of a structured methodology containing design stages that are defined in the exact sequence. The present study aims to create the unfoldings of complex three-dimensional models by covering the stages of providing accessible resurses with a personal and commercial license that are transformed in sequence until the ready-made variants.

Automatic Unfolding of CityGML Buildings to Paper Models

“…For CAD programs such as Blender (https://docs.blender.org/manual/en/latest/ addons/import_export/paper_model.html (accessed on 23 November 2021)), there exist plug-ins that can be used to convert 3D models into print templates for paper models, cf. [12]. However, currently available free tools do not support an easy conversion of textured CityGML and CityJSON objects into textured CAD models.…”
