Description

Изобретение  вл етс  формой выполнени  нагл дного пособи  по начертательной геометрии по авторскому свидетельству № 43214, в которой дл  обозначени  линий в пространстве применены нат гиваемые между плоскост ми проекций нити, дающие возможность получать реально надлежащим образом расположенные линии, проекции которых были изображены-на эпюре.The invention is a form of performing the textbook on descriptive geometry according to the author's certificate No. 43214, in which strands of yarn between projection planes are used to indicate lines in space, making it possible to obtain really properly arranged lines, the projections of which were depicted in the diagram.

На чертеже фиг. 1-3 изображают примеры выполнени  предлагаемого пособи , представл ющие эпюры различным образом взаимно расположенных линий.In FIG. 1 to 3 depict exemplary embodiments of the proposed manual, representing diagrams of differently interrelated lines.

Материалом дл  изготовлени  предлагаемых нагл дных пособий служит или тонкий картон или плотна  бумага, частично же на изготовление моделей нужна прозрачна  бумага, нитки и бусинки . Размер бумаги предпочтительно брать стандартный-VieH Vsa стандартного листа чертежной бумаги. На бумагу наноситс  ручным способом или лучще печатанием плоскостное изображение, делаютс  в некоторых местах прорезы и через некоторые места прот гиваютс  нити. Перегиба  части плоскости изображени , можно получить пространственную модель, а расправл   бумагу, от пространственной модели можно снова перейти к плоскостному изображению.The material for the manufacture of the proposed stencils is either thin cardboard or heavy paper, and in part for the manufacture of models we need transparent paper, threads and beads. Paper size is preferably taken from standard-VieH Vsa standard sheet of drawing paper. A planar image is applied to the paper manually or better by printing, cuts are made in some places and yarns are drawn through some places. By kinking a part of the image plane, you can get a spatial model, and straightened the paper; from the spatial model, you can again go to a planar image.

В примерах выполнение пособи , изображенных на фиг. 1-3, представлены эпюры следующим образом взаимно расположенных линий, а именно: а Ь, а 6 параллельно cd, с ef, е / пересекаютс  с kt, k Л; тп, то л перекрещиваютс  с pq, р ЧIn the examples, the implementation of the manual depicted in FIG. 1-3, the diagrams are presented as follows of mutually spaced lines, namely: a b, and 6 parallel to cd, with ef, e / intersect with k, k L; tp, then l intersect with pq, p h

Перегнув эпюр по оси проекции, а также поставив вертикальную плоскость проекции перпендикул рно к горизонтальной плоскости проекции и нат нув нити между точками 6 и а, d и с (фиг. 1), /, /1 и /г (фиг. 2), и q, т и п (фй1. 3), получают в пространстве , реально надлежащим образом расположенные линии, проекции которых были изображены |на эпюре.Bending the diagram along the projection axis, and also placing the vertical projection plane perpendicular to the horizontal projection plane and pulling the thread between points 6 and a, d and c (Fig. 1), /, / 1 and / g (Fig. 2), and q, t and n (f1. 3), get in space, really properly arranged lines, the projections of which were shown on the plot.

Предмет изобретени .The subject matter of the invention.

Форма выполнени  пособи  по авторскому свидетельству № 43214, отличающа с  применением нат гиваемых между плоскост ми проекций нитей, служащих дл  обозначени  линий в пространстве, проекции коих изображены на плоскост х проекций.The form of the manual according to the author's certificate No. 43214, distinguished by the use of projection yarns between the planes, which serve to mark lines in space, the projections of which are depicted on the planes of the projections.
