How do you draw a cuboid with a sketch?

According to the structure drawing method, the shape is partially formed, and there is no need to draw the inner structure line, and find out the projection position and the shape of the projection.

2. Draw a long line with the side of the pen to lay the tone of the dark side and the projection together, and then accentuate the projection and the dark side respectively. Note that the color of the projection is heavier than the color of the dark side, the upper left corner of the dark side is the heaviest part, and its diagonal position is reflective, which is also the brightest part of the dark side.

3. Use a pen or paper towel to gently wipe the part on the tone, don't use too much force, and avoid rubbing the lead powder into the paper, causing the picture to be reflective and not deep.

4. Use long lines to lay out the background and table top in the picture, also do not do it in one step, do not draw too heavy at one time, use the side for the first time, and determine the large black and white relationship: the background is dark, and the table is bright.

5. Carry out a comprehensive and in-depth picture. The most important part is the edge facing us, which is also the chiaroscuro boundary of the cuboid, which is the most solid and the most contrasting part of the picture, and the position of its diagonal is the weakest part of the chiaroscuro. For the heaviest part of the picture, we must draw it several times when we increase the tone, instead of painting it to the heaviest again, and compare it as a whole every time, and keep up with the tone of other parts to maintain the correctness and accuracy of the relationship between black, white and gray in the picture.

Xiao Zhu talks about sketching: the specific requirements and essentials of cuboid painting, the specific requirements of each line, angle and so on.

A parallelogram is drawn on the top, a rectangle is drawn on the front....Hey, kindergarten children can draw?

To learn. Sketch drawing of a cuboid.

You can learn it here.

Near big and far small, just remember it

Prepare materials: a piece of paper, a pen.

1. First draw a rectangle on the paper and try to be as regular as possible.

2. Draw a parallelogram on the top of the rectangle, as shown in the figure below.

3. To draw the parallelogram on the left, you only need to draw a downward vertical line, and then connect the remaining points, as shown in the figure below.

4. Next, you have to draw a line that you can't see inside, so replace it with a dotted line, and first draw a downward dashed line.

6. Connect the longest one with the dotted line and it's done. <> shown in the figure below

<> underline the paper on the paper jam as shown below. (If you press your own size, you can do it) cut it out with scissors according to the line. (follow the outermost line).

As shown in the figure above, the position needs to be folded inward, and the edges and corners should be folded according to the lines.

Glue the seams with adhesive strips, and the cuboid is complete.

Sketch of the rectangle: according to the structural drawing method, the shape is partially formed, there is no need to draw the inner structural line, find out the position of the projection and the shape of the projection; Use the side of the pen to draw a long line to lay out the dark side and the projection together, and then accentuate the projection and the dark side separately. Rectangular'Sketch:

The cuboid sketch is as follows:

1. Prepare a sketchbook and pencil, and use a 2b pencil to draw the structure of the cuboid in the sketchbook.

2. Next, use the HB pencil to draw lines on the shape of the box.

3. Then, use a 2b pencil to draw a deepened line on the shape of the box.

4. Next, use a 4B pencil to draw the light and dark areas on the shape of the box.

5. Then, use a 4b pencil to draw a shadow shape in the background graphic area of the box.

6. Finally, you can use a 2h pencil to draw a square figure as a whole to show a three-dimensional effect, and through this operation, you can draw a good box sketch figure.

A cuboid is a three-dimensional figure surrounded by six rectangles (in special cases, two opposite faces are squares), called a cuboid. The cube is also a special cuboid. Box:

An enclosed three-dimensional figure enclosed by six rectangles is called a cuboid, and the opposite side of any one of the sides of the cuboid is exactly the same as it.

Each rectangle of the box is called the face of the box, the line where the face intersects is called the edge of the box, the point where the three edges intersect is called the vertex of the box, and the length of the three edges that intersect a vertex is called the length, width, and height of the box.

The bottom is a rectangular straight parallelepiped. The length, width, and height of the cuboid are three degrees, and the sum of the squares of the three degrees of the cuboid is equal to the square of its diagonal. The volume of a box is equal to the product of its length, width, and height.

Sketch a cuboid and draw a rectangle after confirming the structure of the geometric shape. Cuboid sketching, first use long straight lines to gently outline the outline and structure, after confirming the structure of the geometric shape, draw a rectangular shadow to increase the layering of the cuboid, it is best to make in-depth depiction adjustments.

Cuboid sketch method:1. Use a 2B pencil to sketch the basic outline of the cuboid. Notice the perspective relationship of the box.

2. According to the position of the light source, draw the boundary line between light and dark and its projection. Notice the change in the shade of tone.

3. Use pen and paper to wipe the tone of the dark side and projection to make the picture unified.

4. Use a 2B pencil to draw the gray tone on the upper part of the cuboid. Pay attention to the way you arrange the wires.

5. Use a 4B pencil to draw the overall tone of the cuboid background. Pay attention to the density and variation of the cables.

6. Then, add the dark tone of the cuboid background. Pay attention to the direction of the cables.

7. Strengthen the overall portrayal of the dark side and background of the cuboid to make the picture have a sense of space.

A cuboid (also known as a cuboid) is a straight quadrangular prism with a rectangular base (or a straight parallelepiped with a rectangular bottom and a rectangle at the top and bottom). It is made up of six faces, which are equal in area to each other, and two faces (four faces may be rectangular, or all six faces are rectangular) are squares.

A cuboid is a straight prism with a rectangular base. A cube is a special cuboid, and a cube is a cuboid with six sides square.

Each rectangle of the box is called the face of the box, the line where the face intersects is called the edge of the box, and the point where the three edges intersect is called the vertex of the box. The sum of the six faces of the box is called the surface area of the box. The volume of a box is a measure of a box, and the volume of a box is equal to the product of length, width, and height.

The easiest way to draw a cuboid is as follows:Materials to prepare: white paper, ruler, pen.

The operation is as follows: 1. Let's draw a rectangle first.

2. The length of the two short sides is the same.

3. Draw the top of the cuboid.

4. Draw two diagonal parallel lines above the two short sides.

5. Draw the long side of the plane above.

6. The length is the same as the long side of the rectangle we drew at the beginning.

7. We draw the short side of the rectangle vertically.

8. This side is parallel to the short side of the previous plane of the box.

9. Just draw it with a dotted line.

10. Such a complete cuboid is drawn.
