Hi folks, You all know the fuselage-sections of a plane and probably also how to construct such a cone on a piece of paper. In Dutch it's called a 'uitslag', a mathematical expression, so in case of a cone it's called an 'uitslag' of a cone. But of course it does not have to be cone at all. You also can make an 'uitslag' from a box, resulting in 6 squares/rectangles. How do you call an 'uitslag' in English ? Even Wikipedia does not give an answer. Sticky greetings from Holland, Gerard http://home.deds.nl/~gahm/index.htm

Are you talking about the 2-D unfolded representation of a 3-D object? Maybe the word you're looking for is "projection"? Such as with world maps, the globe, a sphere, is represented on a 2-D surface using something like a Mercator projection. Though projections seem to be distorted perspectives of the object in question. Maybe you're just looking for "unfolded surfaces". We usually talk about taking a 3-D model and using the software Pepakura to "unfold" it into separate parts.

The pattern of six squares/rectangles for the box would be called a net. If you search for polyhedra nets you will find a lot of information. Here is a site with lots of nets of lots of polyhedra: Paper Models of Polyhedra

Thanks for your reactions. The solution came from www.wetenschapsforum.nl : English = the development French = le développement German= die Abwicklung I'll carry on with the translation of my site. Kind (tiny ) greetings, Gerard
