Actually the shape that I have used in an illustration in a pdf, using an illustration produced by exporting a png from Serif ImpactPlus 5, is a 3d shape that is an extruded 2d shape.
I worked out that it would need a special bronze die to be used in an ordinary pasta-making machine.
I used Serif ImpactPlus 5 to produce a concept illustration.
I have really enjoyed building 3d models in ImpactPlus 5. However, although one can rotate the model in ImpactPlus one cannot export a model that an end user can rotate.
I suppose that I am wanting something like the combination of ImpactPlus, Google Street view, vector graphics, animation sequences at times, end user interaction and then telecommunication of all that using plain text and a colour font.
It seems quite a lot to want but I wonder how far off that would really be if 3d glyph capability is added to OpenType. .
