Abstract—Buildings are complex products containing relatively large numbers of distinct parts that are collected in multiple assemblies for different design, analysis and production purposes. Modeling buildings in fully parametric 3D computer-aided design
(CAD) systems offer numerous benefits in terms of productivity, the ability to rapidly generate design alternatives at different levels and elimination of errors that result from the disparity between different …show more content…

Solid modeling provided for the representation of volume-enclosing sets of surfaces and powerful editing operations that allowed single operations for gluing shapes together or subtracting one shape from another, while preserving volume-enclosing properties. Solid modeling operations combined with curved surface editing of the solid’s faces (their bounded surfaces) allowed easy definition of any 3D shape on a computer and enabled assembly of multiple shapes. Solid modeling allowed many of the original goals of 3D CAD to be realized: accurate representation of a three-dimensional shape; automatic derivation of any shape measurement, including volume and surface areas; cutting of sections, including automatic derivation of section properties; automatic drawing generation of parts or assemblies, with automatic dimensioning. Solid modeling also allowed automatic checking of spatial interferences between assemblies, and with fully defined shapes, sufficient information was available to support numerical control machining or other fabrication
