Embodiment Construction

[0028] The hollowed out cube is composed of 12 parts, 12 parts, 12 parts in total; the dotted line is used to indicate the front fold line, that is, when folding, the front side and the front side of the paper are folded relative to each other; the solid line plus a circle indicates the reverse side The anti-folding line of half-folding, that is, when folding, the reverse side of the paper and the reverse side are folded relative to each other; the dots on the solid line indicate the indicator line;

[0029] Take a rectangular paper with a length-to-width ratio of 4:3, and make two vertical lines, that is, the left and right vertical indicator lines, and the two vertical lines divide the rectangular paper into three congruent vertical small rectangles, that is, the left , middle and right vertical small rectangles; make two horizontal lines, that is, upper and lower horizontal indicator lines; two horizontal lines and two vertical lines make the four corners of the rectangular ...

Abstract

The invention provides a hollowed-out cube, and relates to a manufacturing method for a solid figure. The hollowed-out cube is formed by assembling twelve same components. The method comprises: taking a piece of rectangular paper whose length-to-width ratio is 4 to 3, making oblique line positive broken lines, and folding the paper into a hexagon shape according to the lines; making a long reverse broken line on the hexagon; according to a left longitudinal positive broken line and a right longitudinal positive broken line, folding the left part and the right part of the hexagon to the middle part, to form an interlayer longitudinal small rectangle; making a short reverse broken line; and plugging of two components: the insertion portion of a first component being inserted into an inserted opening of an inserted portion of a second component, inserting until the intersection points of the insertion portion and the inserted portion overlap, the short reverse broken line of the insertion portion being overlapped with the long reverse broken line of the inserted portion; plugging three components to form a combined corner; plugging four components to form a plane of a combined square; plugging twelve components to form the hollowed-out cube with six combined square planes and eight combined corners. The hollowed-out cube is exquisite in design and regular in folding, simple in component manufacturing, easy in plugging, beautiful and elegant in appearance, and is firm.

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, known cubes that are fully enclosed are more common, and hollowed out cubes are relatively rare. Contents of the invention [0003] In order to overcome the relatively rare shortcomings of the existing hollowed out cubes, the invention provides a method for making the hollowed out cubes. [0004] The technical solution adopted by the present invention to solve the technical problem is: the hollowed out cube is composed of a total of 12 identical parts from part one, part two...part twelve; [0005] Take a rectangular paper with a length-to-width ratio of 4:3, and make two vertical lines, that is, the left and right vertical indicator lines, and the two vertical lines divide the rectangular paper into three congruent vertical small rectangles, that is, the left , middle and right ver...
