Geometry sketchers and CAD Tools can provide a highly valuable help for machine design and industry in the context of mechanism synthesis. They can be used at an early stage of mechanism development when the design is specified in a preliminary way. In order to get a deeper insight in options and features of software tools for the dimensional synthesis, this paper compares the possibilities of two geometry sketchers (Cinderella© and GeoGebra©) and two CAD systems (Inventor Professional©, CATIA V5©). Different synthesis procedures are presented and described in algorithmic form. Necessary functionalities that should be provided by the software tools are derived. Different synthesis examples are shown: a windscreen wiper mechanism and a spherical four-bar linkage.
