Template-based traditional building component modelling

Abstract

Creating 3D object models is a crucial in many areas such as computer graphics, virtual reality, animations, and computer aided design(CAD). In this paper, we discuss our ongoing research on creating traditional building component modelling using component templates. We developed a prototype system that can create building component templates by editing fundamental 3D object primitives using the open source CAD software FreeCAD. Once a building component template is created, it will be segmented and anlalyzed to select the unit shapes that are commonly and frequently used for a variety of component templates, and they will be registered back into the primitive database so that they can be used in creating other templates in the future. Our system provides easy-to-use editing tool that a user can create the shape of the building component and then the system automatically generate a set of parameters necessary to describe the shape. Our experience showed that users can easily create the component templates they desire to make in a few minutes.

“…FreeCAD is aimed directly at mechanical engineering and product design; however it also fits in a wider range of uses around engineering, such as architecture. [162] [163] [131] [166] FreeCAD's focus is to allow user to create high-precision 3D models, to keep tight control over those models (being able to go back into modelling history and change parameters), and eventually to build those models (via 3D printing, CNC machining or even construction worksite). [163] FreeCAD has many 2D components in order to sketch 2D shapes or extract design details from the 3D model to create 2D production drawings; Nevertheless, direct 2D drawing (like AutoCAD LT) is not the focus, neither animation or organic shapes are (like in Maya, 3ds Max, Blender, or Cinema 4D).…”

“…Python scripting can also be used in macros, which provide an easy method to create custom commands. [163] [131] [166] The main concept behind the FreeCAD interface is that it is separated into workbenches. A workbench is a collection of tools suited for a specific task, such as working with meshes, or drawing 2D objects, or constrained sketches.…”
