Abstract:
The paper compares and contrast capabilities of the two software Alias Computer Aided Industrial Design software (CAID) and I-DEAS Mechanical Computer Aided Design Software (MCAD) on the modelling of artefacts which have got freeform geometry. Freeform geometry is the geometry which uses surves and surfaces, which is not made up of Constructive Solid Geometry (CSG) such as cubes, spheres, and cylinder. The purpose of this case study is to find out the capabilities of two sofware to model the freeform objects. To compare the two software, a mobile handset having a typical and challenging freeform geometry has been used. The modelling of the mobile handset and various parameters that wre taken into consideration are discussed. The problems which were faced while modelling are discussed followed by its solutions.
