With the continuous progress of computer technology, the application of computer technology in engineering design is more and more common, especially the popularization of CAD technology, which brings great convenience to the drawing of engineering design. The following is the application of CAD technology in water conservancy projects that I searched for you. Welcome to read, I hope it will help you! For more information, please continue to pay attention to our fresh graduates training network!
Since 1970s, the technology represented by CAD technology has swept the world, which not only promoted the improvement and upgrade of computer performance, but also affected all technical fields and impacted the traditional working mode. The technology represented by CAD will further bring great influence and benefits to mankind. Now the level of CAD technology has become a symbol to measure a country's industrial technology level. At first, two-dimensional CAD system occupied a dominant position in the field of CAD. At present, 3D CAD technology has become more and more mature and widely used.
First, the design ideas of water conservancy projects
The traditional design idea of hydraulic engineering is to design buildings on drawings and then study the scheme, but these works are all based on hand drawing on the plane, so the design of buildings is always unsatisfactory and some of them are not harmonious enough. In addition, if the drawings need to be revised, a lot of work is needed, which will bring some unnecessary work. Using CAD to draw design drawings can avoid these problems and bring good design results.
Because CAD has a very powerful three-dimensional drawing function, we can draw an ideal effect diagram according to the design idea. By observing the renderings, adjustments can be made in time, laying a good foundation for better completion of the design work.
Moreover, the three-dimensional effect diagram of CAD can be easily converted into a plan, which not only reduces the workload of designers, but also facilitates the modification and improvement of design drawings.
Second, the advantages of CAD technology in hydraulic engineering design
1. Improve the accuracy of water conservancy engineering drawing
The graphic calculation function can improve the accuracy of hydraulic engineering drawing. Because of the complexity and particularity of hydraulic engineering itself, many calculation methods of hydraulic engineering can only meet the accuracy requirements in theory, but in the actual calculation process, many values are calculated by experience or reasoning, and some cannot be calculated at all because of the uncertainty of various conditions. Therefore, in the calculation of water conservancy projects, many calculation methods are often simplified when the accuracy meets the engineering requirements, and graphic method is one of the widely used methods. After AutoCAD uses the corresponding method to draw the calculation chart, it can get the corresponding data conveniently and quickly as long as it is intercepted in the corresponding place. It can also be widely used in engineering design, and the values of various parameters can be obtained by interpolation, and the relationship curves and tables can be checked. Therefore, the graphic calculation function can quickly calculate data, and then improve the accuracy of hydraulic engineering drawing.
2. Improve the effectiveness of water conservancy engineering drawing.
Office has become a well-known universal software. With the continuous improvement and development of AutoCAD, its software related to Office has been integrated with each other and achieved good results. In terms of text combination, AutoCAD is usually used to calculate the pressure of dam foundation and gate. In the production of Word documents, various illustrations are often needed. This shortcoming is more obvious because of the limited drawing function of Word, especially for complex graphics. AutoCAD is a professional drawing software. When making graphics, it is a good way to solve this problem by inserting Word to make compound document. You can use the export function provided by AutoCAD to output AutoCAD graphics in BMP or WMF format first, and then insert them into Word documents. You can also copy AutoCAD graphics to the clipboard first, and then paste them into a Word document. In water conservancy projects, if you want to list the materials in cofferdam and bridge construction drawings, you need to make tables in AutoCAD, draw tables manually in AutoCAD environment, and then fill in the tables with words, which is not only inefficient, but also difficult to accurately control the writing position of words, and text typesetting has become a problem. An efficient way to make a table is to make a table in Excel, copy it to the clipboard, and then select it in AutoCAD. Editor? On the menu? Paste special? , select an AutoCAD entity, and then click OK to convert the table into an AutoCAD entity. AutoCAD entity, after confirmation, the table will be converted into AutoCAD entity. This improves the efficiency of drawing.
3. Improve the speed of water conservancy engineering drawing.
Automatic quadrature module can improve the rapidity of water conservancy engineering drawing. There are many graphic calculations in hydraulic engineering design, so when drawing hydraulic engineering drawings, it is necessary to use automatic quadrature module to calculate the graphics. There are many automatic quadrature functions in AutoCAD, such as length calculation, perimeter calculation, area calculation and so on. Generally speaking, as long as there are no mistakes in drawing, the characteristics of each drawn object can be displayed conveniently and accurately, and it is easy to mark it after setting the scale and accuracy. This is of great help to engineering designers in data statistics and calculation, especially for the calculation of irregular objects, such as the calculation of cross-sectional area and perimeter, the calculation of plane area and perimeter, and the calculation of total length of pipelines. This not only makes it very convenient and fast to obtain numerical values.
Third, the discussion about CAD drawing
Steps of 1.CAD drawing
(1) Basic drawing parameter setting; (2) Flexible application of layers; (3) pattern filling; (4) input of characters; (5) Draw points, curves and primitives.
2. Basic problems in 2.CAD drawing
(1) Selection of drawing scale.
It can be drawn with the ratio of 1: 1, and the output ratio can be adjusted at will. Among them, drawing scale and output scale are two different concepts.
(2) Rational utilization level.
Rational use of layers can get twice the result with half the effort. When you start drawing, you can set some basic layers in advance. Each floor has its own purpose. The advantage of this is that you can combine many required drawings by drawing a drawing file, and you can modify it for the layer if necessary.
(3) Reduce the file size appropriately.
After the drawing is completed, the file size can be effectively reduced by executing the cleaning command and cleaning up redundant data.
3. Output and printing of drawings
If the drawing printing effect is average, it can be solved by the following methods.
(1) Whether to turn off the error jitter switch when configuring the printer or plotter.
(2) Whether the driver of the printer or plotter is correct and whether it needs to be upgraded.
(3) If AutoCAD is configured to output as a system printer, please use ADI drivers provided by AutoCAD for various printers and plotters to reconfigure the AutoCAD printer.
(4) AutoCAD provides corresponding commands for different types of printers or plotters, which can be further configured in detail.
With the increasing popularity of computers, AutoCAD drawing has been widely used in hydraulic engineering design. The powerful function of AutoCAD can help us draw accurately and quickly. After adopting CAD technology, engineers and technicians can carry out a series of technologies such as scheme optimization, numerical calculation and construction drawing design. Strengthen the secondary development of CAD, improve the quality of design drawings, shorten the design cycle, effectively avoid mistakes, bumps, leaks and leaks in manual design, thus reducing the project cost, ensuring investment savings and improving production efficiency.
