[0002] The key to painting lies in form, and the key to form lies in mastering perspective. However, traditional perspective teaching is far too complex. In practice, most teachers only teach that objects appear larger when closer and smaller when farther away, but rarely explain how the precise principles of perspective drawing are derived. Therefore, most perspective teaching methods are rather crude, and even some perspective books on the market contain errors. For this reason, this solution has been developed to easily address the problems in teaching perspective. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technology and provide a geometric object for drawing and a drawing method.

The protruding pillars and the circular holes are inserted and pulled together. A plurality of bars A and a plurality of bars B can be inserted and connected to form a cube, cuboid, square, or trapezoid; each face of the cube is divided into sixteen cubes, and the square is divided into sixteen cubes.

[0005] As an improvement, the following drawing steps are included:

[0006] Step 1: Draw the center diagonal line on each of the cubes at each corner;

[0007] Step 1: Draw a circle at the center of each face of the cube, the circle being tangent to the edge of the cube;

[0008] Step 1: Mark the four tangent points and the intersection of the circle and the diagonal of the corner cube;

[0009] Step 1: Draw a circle in the center of the square, the circle being tangent to the edge of the square.

[0010] As an improvement, the materials of bar A and bar B are transparent plastic or transparent rubber or magnetic metal.

[0011] The advantages of this invention compared to existing technologies are as follows: This drawing method uses geometric shapes and techniques to quickly determine the eight points of a cube, solves the problem of drawing circles in solid form, and accurately finds points where objects appear larger in the distance. Compared to traditional geometric shapes, it offers several advantages: it provides various structural lines for easy structural visualization; it is not easily broken or soiled; it can be used as a decorative item when connected to a light; and users can write their favorite proverbs, maxims, or draw their own pictures, which can then be pasted inside the transparent geometric shape for a lifetime. This perspective teaching method can save over 80% of the time. Because it solves the perspective problem, the structure is easily drawn accurately, making it highly practical and valuable for widespread application. Attached Figure Description

[0035] Combined with appendix Figures 1 to 21 A geometric solid for drawing and a drawing method, comprising bars A1 and B2, wherein bar A1 has a plurality of protruding posts 3 arranged in a row, and bar B2 has a plurality of circular holes 4 arranged in a row, wherein the protruding posts 3 and the circular holes 4 are inserted and pulled together, and a plurality of bars A1 and a plurality of bars B2 can be inserted and connected to form a cube 5, a cuboid, a square 6, or a trapezoid; each face of the cube 5 is divided into sixteen square blocks 7, and the square 6 is divided into sixteen square blocks 7.

[0036] The following drawing steps are included:

[0037] Step 1: Draw the center diagonal line on each of the cubes 7 at each corner;

[0038] Step 2: Draw a circle 8 at the center of each face of the cube 5, wherein the circle 8 is tangent to the edge of the cube 5;

[0039] Step 3: Mark the four tangent points 9 and the intersection of the circle 8 and the diagonal of the corner cube 7;

[0040] Step 4: Draw a circle 8 in the center of square 6, where circle 8 is tangent to the side line of square 6.

[0041] The materials of the bars A1 and B2 are transparent plastic, transparent rubber, or magnetic metal.

[0042] In specific implementations of this invention, bar A1 and bar B2 can be spliced ​​together to form various shapes. When drawing, simply follow the steps described above.

[0043] 1. The foundation is geometric perspective: a completely new perspective method that combines the study of plane geometry, solid geometry, approximation concepts, and traditional perspective to study perspective in painting. This perspective method has resulted in two sets of patents: a plane perspective ruler and a set of new geometric shapes on which the structural lines of this method are drawn on the surface of geometric objects.

[0044] 1. A planar perspective ruler. A ruler that can visually represent perspective changes on a plane. Its features include a rod A1 and a rod B2. The rod A1 has a row of protruding posts 3, and the rod B2 has a row of circular holes 4. The protruding posts 3 and the circular holes 4 are inserted and pulled together. Several rods A1 and B2 can be connected to form perspective diagrams of various geometric shapes such as a cube 5, a cuboid, a square 6, and a trapezoid.

[0045] Materials: Transparent plastic, acrylic glass; or magnetic metal sheet.

[0046] 2. A set of geometric figures that depict the structural variations of various geometric shapes.

[0047] A. The transformation diagram of the cube is the basis of this method.

[0048] Each face of the cube 5 is divided into sixteen squares 7, and the square 6 is divided into sixteen squares 7.

[0049] Its characteristic is that it includes the following drawing steps:

[0050] Step 1: Draw the center diagonal line on each of the cubes 7 at each corner;

[0051] Step 2: Draw a circle 8 at the center of each face of the cube 5, wherein the circle 8 is tangent to the edge of the cube 5;

[0052] Step 3: Mark the four tangent points 9 and the intersection points of the circle 8 with the diagonals of the corner square 7;

[0053] Step 4: Draw a circle 8 at the center of the square 6, and the circle 8 is tangent to the sides of the square 6.

[0054] The purpose is to find four intersection points of the central circle with the two diagonals in addition to the four tangent points. In this way, 8 points are found, so that the circle can be drawn accurately very easily.

[0055] In this method, a formula equivalent to a theorem is found:

[0056] 1 / 6<a / b<1 / 5 (a divided by b is greater than one sixth and less than one fifth

[0057] 3. Various geometric bodies other than cubes are also drawn with corresponding structural diagrams.

[0058] 4. Note: Through these geometric bodies with various structures drawn, using the special method of geometric perspective, the perspective method can be quickly mastered in a concise and easy-to-understand manner.

[0059] Materials: Transparent plastic, organic glass or metal plate (with lines), wood board (with lines can be used. The transparent ones can also be added with energy-saving lamp interfaces. Compared with traditional geometric bodies, they have the following major advantages: various drawn structural lines make the structure clear at a glance; they are not easy to break; not easy to get dirty; they can be used as decorations when connected to a lamp; you can write your favorite mottos and aphorisms, draw your favorite small pictures, and paste them on the inside of the transparent geometric body, which can be used for a lifetime.

[0060] This set of perspective teaching can save more than 80% of the time. Since the perspective problem is solved and the structure can be drawn accurately easily, students who have mastered this modeling method all feel that they are geniuses.
