This sections shows a range of illustrative examples
of how PolyCAD can be used to model a range of different surface
shapes. The software has a range of tools so that depending on the
complexity of the surface the right tool for the modelling task
can be selected. These illustrations show the modelling stages that
a surface may go through to achieve a particular shape. Tutorials
can be found in the help which show the modelling process in more
detail and illustrate the commands and user interface tools used
to develop the surfaces.
