Abstract: A computer-implemented method is provided for rendering, to a designer, a two-dimensional image of an assembly of part instances in a three-dimensional assembly space within a computer-aided design (CAD) system utilizing double precision to describe part assemblies. Such assemblies are considered to be distant from a nominal observer. A viewport on a two-dimensional image plane is defined, and a combined transform is defined in quadruple precision to enable the generation of clipping lines and/or clipping points. The clipping lines and clipping points clipping the faces and edges of the part instance in the assembly to the portion of the assembly that lies within the viewport.
