Abstract: A computer-implemented method of handling large transforms in a computer-aided design (CAD) solid model utilizing double precision to describe a physical assembly of parts is described. If the unit size of a transform of interest exceeds a pre-determined threshold, the double precision of the transform is converted to quadruple precision whilst maintaining the double precision of the assembly. The results of any operation are output in double precision. A computer program and method of adapting an existing CAD model are also described.
