Crossing solid figure

Abstract

The invention provides a crossing solid figure and relates to a manufacturing method for geometry. The crossing solid figure is formed by combining six same components. The method comprises the following steps: taking a piece of square paper and folding the square paper into a folded longitudinal rectangle; folding and deforming the rectangle into an octagon with an upper isosceles trapezoid, a lower isosceles trapezoid and four four-layer isosceles right-angled triangles; further folding into a component; arranging the four-layer isosceles right-angled triangles as grafting parts for grafting the components; forming interlayer openings, namely, grafted openings for grafting the components, at the openings of small squares 21, 25, 41, 45; respectively grafting one set of two grafting parts of the first component into two grafted openings of the second component, namely, finishing once grafting of the two components; similarly grafting, thereby grafting the six components into the crossing solid figure. The design is fantastic; the component manufacturing is regular; the component combination is simple; the modeling is peculiar and beautiful.

Description

technical field [0001] The invention relates to a method for making a geometric body, in particular to a method for making a three-dimensional shape. Background technique [0002] At present, the known cross-dimensional shapes are mostly flaky, relatively skinny, and not plump enough. Contents of the invention [0003] In order to overcome the disadvantages that the existing cross three-dimensional shape is mostly flake, relatively skinny, and not plump enough, the invention provides a method for making the cross three-dimensional shape. [0004] The technical scheme adopted by the present invention to solve its technical problems is: the cross-dimensional shape is composed of six identical parts in total of part one, part two...part six; [0005] Take the square paper, draw the first horizontal indicator line, the second horizontal indicator line, the third horizontal indicator line, and the fourth horizontal indicator line parallel to the upper and lower paper edges of ...
