CASE, K. and ACAR, B.S., 1990. Comparative study of geometry specification capabilities of geometric modelling systems. IN: INTERACT '90: Proceedings of the IFIP TC 13 Third International Conference on Human-Computer Interaction, Cambridge, 27th-31st August 1990. Elsevier, pp. 345 - 350.
This paper describes experimentation carried out with a novel computer aided design
system which uses 'manufacturing features' as the principal method by which the
designer specifies the geometric part of design. The approach has been experimentally
compared with the more traditional methods of two dimensional computer aided draughting
and solids modelling. With skilled industrially-based design engineers such a features
approach compares well with the other methods in terms of the user time and the
accuracy and completeness of the final models.
Learning studies in the new technique and a large scale attitude survey are
also briefly described.
