Advice 1: How to make a sheet for drawing

Previously charted on the drawing boards, now for this there are special programs. But before you can use the professional approach, it is necessary to master elementary level. And learn how to properly execute the drawing.
How to make a sheet for drawing
You will need
  • A sheet of drawing paper of any standard size, t-square, a long straightedge, squares, sharpened pencil
Instruction
1
Place a A4 sheet vertically. Drawing paper of a larger size can be used in this, and in a horizontal position. There are five main formats: A0 sizes 841х1189 mm; A1 - 594 x 841 mm A2 - 420 x 594 mm A3 - 297 x 420 A4 210 x 297 mm. you Can take and additional formats, if the shorter side of any of the major increase in multiples of its size.
2
Make frame. To do this, start from the edge of the sheet by 20 mm on the left side and 5 mm on other three sides. Put points on the measured distance, in the middle of each side and in the corners and slide through them straight lines. The frame should be made continuous main line. In terms of drawing, it means a more bold and brilliant than the rest. Use hard-soft pencil.
3
Draw your titleblock. It is called "stamp" because its size and performance are regulated by state standards. Measure on the bottom side of 145 mm and with the straightedge from this point draw a line upward at right angles. Put on it is 22mm and the right frame of the sheet. Connect the resulting points, and slide the border and a solid main line.
4
Create the internal structure of the sheet. Put on the right and left side of the stamp to 8 mm from the bottom line. Connect the intended point horizontal. From the left corner of the stamp, measure 70 cm lower and upper border of the stamp. Draw a vertical main line. Other parts follow a more subtle.
The dimensions of the stamp
5
Aside from the left corner of the stamp at the upper boundary, alternately 25 and 30 mm. Measure the same cuts on the second from the bottom horizontal line. Connect the dots vertical. On the left frame of the stamp from top edge back down 7 mm and the Central vertical line. Swipe horizontal. Now from the bottom right corner of the frame set aside for each other by 20 mm and draw a vertical line up to the next horizontal. The main inscription is prepared.
6
Complete the stamp according to the requirements of the standards. School works has its own rules. In the upper right column, specify the name of the product, under it left-to-right material, size and markings according to GOST. To the left on the top line write: "Features" - and then name and the date of manufacture of the drawing. Below the word "Checked". A neighboring cell, leave blank. On the last line, specify the school and class. Students indicate their group.

Advice 2 : How to draw a frame for the drawing

To make it convenient to store and file drawings, they make the frame and the table with the basic information according to certain standards drawing. They are all described in the Standards.
How to draw a frame for the drawing
Instruction
1
Building the framework runs the main by a thin line. Always when holding a frame with three sides of the sheet retreat from the edge of 5 mm and 20 mm on the plane of the sheet inside the frame is called the field of the drawing. The widest part of the frame, the width of which is 20 mm, used in the binder. There is enough space to pierce the holes for the folder.
2
In the lower right corner of the sheet draw sheet is a table with information about the drawing. Its size is also strictly described in the standards. Students draw a sheet with a size of 145 mm in length and 22 mm in height.
3
In the production of a A4 sheet vertically, so the frame is draw vertically. The school sometimes allowed to place the sheet horizontally. On sheets of A3, on the contrary, the frame is always horizontal. This is done in order to be able to sew in the same folder as sheets of different format, because the big side of an A4 sheet is equal to the smaller side of A3 sheet.

Advice 3 : How to draw a flowchart

The block diagram is a variant of the formal record of the algorithm or process. Each step of the algorithm, in the representation depicted in the form of blocks of various shapes that are connected by lines. In the block diagram, you can display all steps of the solution of any tasks starting with data input, processing operators, implementation of cyclical and conditional functions, and finishing operations output the resultant values.
How to draw a flowchart
Instruction
1
First, any block-schema check element entering the program. It is indicated with a rectangle with rounded edges, inside it write the command "Start". This will be the starting point of your flowchart. After the initial draw shapes straight line to continue down the flowchart.
2
Generally, the first algorithm is the input data for the task. Draw a parallelogram below the line so that it was an uninterrupted continuation of the scheme. In the parallelogram produced by the write action, this is usually operation of reading data from the screen (Read nInp) or other devices. It is important that you enter the names of the variables in this step will be used throughout the body of a block diagram.
3
Executing one or group of operations, any data processing (the change in the value or form of representation is in the form of a rectangle. Draw this figure in the algorithm in the preparation of a block diagram. Inside the rectangle, write down actions with variables, for example, the assignment operation can be written as follows: mOut = 10*nInp b + 5. Further, as to continue a block diagram draw a line down.
4
An important part of any algorithm and therefore the flowcharts are conditional and cyclic operators. Data operators have one input and two or more alternative exit. After calculating the conditions specified by the operator, a further transition is performed only in one path. Draw the input element in the form of a line included in the top vertex of the element.
5
To set the condition statement to draw from this line rhombus. Inside the shape, specify the condition itself and draw lines indicating a further transition depending on its implementation. The condition is set in the General case, by comparison operations (>, <, =). The transition line down is when the true condition, ago – when about. Indicate approximately the output lines of the figure the results of the conditions (true, false). Failure to comply with condition (false) returns to a specific step above the body of the algorithm. Draw lines at a right angle from the exit terms and to the right of the operator.
6
The cyclic operator is denoted by the rectangles with beveled corners. And to draw this operator uses two edge pieces. The beginning of a cycle is given by figure with beveled upper corners, the end of the cycle – shape with a beveled bottom corners. In the figure the beginning of the cycle specify the operation condition of the cycle and between the perimeter figures to draw the inner loop operator.
7
At the end of the flowchart must contain the output data to the media or on screen. The operator o is drawn similarly to the input statement. Draw a parallelogram and inside it an output operation using the output variables.
8
At the end of a block-diagram draw element-terminator – a rectangle with rounded edges. Inside it write the word "End". The block diagram is complete.

Advice 4 : How to draw drawings design documentation

Drawing and design document, so when the design requires strict adherence to established Standards of regulations. There are many Standards that relate to ESKD – unified system for design documentation. They specify the sizes of sheets, the thickness of the lines, the order of registration. They should be guided to properly execute drawings and design documentation.
How to draw drawings design documentation
Instruction
1
Drawing dimensions should be of the set format from A0 to A4, all formats are multiples of each other and their length and width are determined with millimeter precision. Format A0 has a size of 841х1189 mm A4 – 210x297 mm.
2
A mandatory condition of a properly executed drawing are the frame and the main inscription. Top, bottom and right margin of the frame is 5 mm. the Left margin of the frame is 20 mm, so that the drawing can be filed in a shared folder. The thickness of the frame line is 0.5 mm. the drawing is performed using different types of lines. They depend on the thickness of the main thick line, which may have a thickness from 0.5 to 1.4 mm.
3
In the lower right corner locate the sheet format which is also called stamp. Its shape and dimensions are set in the GOST 2.104-68. On the production drawing, its length should be 185 mm and a height of 55 mm. Field, the size of rows and columns in the sheet have a strictly fixed size. The sheet format contains information about the name of the product, the material from which a manufactured part, made in the drawing, their weight in kilograms, the scale of the drawing. In addition, the stamp put information about the character encoding of the drawing, its manufacturer and the officers who carried out the control and acceptance.
4
General rules of dimensioning and inscriptions refer to GOST 2.307-68. But you should know that is used for the application of special drawing font. If you still do not know how to write them, I suggest you practice on a rough draft before you write the numbers and letters on the drawing. Sometimes to cause the inscription, beautifully and correctly set the size, you can spend time not less than the drawing itself.
5
All drawings are made in accordance with the established scale, so it can be represented as large objects: building, car, and small – detail of the clock circuit. Whatever the scale, the dimensions of the parts are put in the drawing only valid.
