본문내용

This chapter provides an overview of the primary technology that distinguishes BIM design applications from other CAD systems.

Custom parametric objects allow for the modeling of complex geometries, which were previously not possible or simply impractical. - 1980’s program

Current BIM tools vary in many ways

Most architecture BIM design tools let users mix 3D modeled objects with 2D drawn sections, allowing users to determine the level of 3D detailing while still being able to produce complete drawings.

The ability to represent a fixed set of polyhedral forms for viewing purposes was developed in the late 1960s and later led to the first computer-graphics film, Tron (in 1987)

In 1973, the easy creation and editing of arbitrary 3D solid shapes was developed separately by three group.

The boundary representation approach (B-rep) defined shapes using operations of union, intersection, and subtraction on multiple polyhedral shapes and also utilized refining operations, such as chamfering, slicing, or moving a hole within a single shape
