CAD learning tutorial, that is, AutoCAD learning tutorial, there are many new or upgraded versions of the industry released every year, so that users are more and more easy to learn new professional knowledge, master new drawing skills, draw more accurate product drawings, and produce better products. The following is a mechanical professional commonly used drawing software AutoCAD2006 as an example, talk about CAD learning tutorials.
Introduction (including 2 points) (Chapter 1) 1. Introduces the technical development process of CAD, application fields, and the significance of application in professional fields. 2. The configuration requirements of software and hardware for installing AutoCAD on computer are introduced.
Learning the basic knowledge of AutoCAD (Chapter 2) 1. Learning the user interface. You should be familiar with the composition of the working interface when drawing, such as coordinate ICONS, toolbar ICONS, command line Windows, title bars, etc. 2. Basic operation and setup of AutoCAD. Use the drawing tools and commands in the interface for specific basic operations and Settings. 3. Position determination in AutoCAD. Determine the position of the coordinates on the screen where you are drawing the graph.
The use of Basic AutoCAD Commands (Chapter 3) 1. Draw a line, 2. Draw a circle, 3. Draw polygons and rectangles, 4. Draw multi-segment lines, 5. Draw arcs, 6. Draw ellipses and ellipses, 7. Draw points,.8 other editing commands. Each of the above commands has a certain step to complete, and there are different ways to learn the drawing of each basic element through practical operation or video.
Complete AutoCAD mechanical drawing (Chapter 4) 1. Text commands, the font and size of the input text should be completed according to the mechanical drawing regulations. 2. The marking of the size, the marking method, the size of the text, and the direction of the number should be marked according to the provisions of the mechanical drawing. 3. The use of boilerplate files, drawing software has a variety of boilerplate files, you can call out at any time for reference. 4. The use of drawing blocks, you can directly make a part or component into a block for use. 5. Drawing of three views, main view, top view and left view.
Typical mechanical parts AutoCAD design (Chapter 5) 1 standard parts design, mechanical drawing often standard parts, can be directly selected, according to the different professional, you can choose different standard parts design, the professional most commonly used standard parts stored for backup. 2. Shaft parts design, shaft parts are also commonly used in mechanical drawing. 3. Disk parts design, mainly learn the circle and arc, straight line connection, the center of the circle positioning to be accurate. 4. Shell parts design, shell parts are generally relatively complex, requiring the drawing expression to have a beautiful design reflected in the drawing.
The use of AutoCAD reducer design (Chapter 6) in the general mechanical drawing learning process will take the design of the reducer as an example, because it covers the basic knowledge of the drawing is more comprehensive. 1. Block setting, the reducer needs to use the block operation to complete part of the Settings applied to the drawing. 2. Assembly drawing, assembly drawing is the drawing of all parts of the reducer assembly, is to guide the installation drawings of the reducer, so we must learn to use the title bar to express the name, quantity, material and other descriptions of each part.
Introduction to three-dimensional design of AutoCAD (Chapter 7) 1. Basic knowledge, to establish the concept of space, learn the three-dimensional coordinate system of X, Y and Z. 2. Drawing typical shapes. Typical shapes include ball, cylinder, cone, cube, cuboid, etc. 3. Stretching and rotation mainly refers to the stretching and rotation of cylinders, cones, tables, etc. 4. The three application skills of blanking, coloring and rendering are very important to express the quality of stereogram vision. 5. Other typical 3D commands, such as coordinate point position selection, layer operation, block modification and attributes. 6. Draw the basic parts of the reducer, which should be accurately drawn according to a certain size ratio, so that it is easy to use in the assembly drawing.
Printing and drawing (Chapter 8) 1. Set the printing parameters, after the drawing is completed, the drawing should be drawn, and the drawing should be printed out, because the drawing is divided into horizontal and vertical points and size points, so when selecting printing, the printing parameters should be set. 2. Page setting, you can select the partial view of the drawing to set the page.
Because CAD involves a wide range of industries, construction, home improvement, electrical appliances and other industries, the selection of learning tutorials are not the same, so choose to learn CAD. You have to choose from a major.
First learn the professional knowledge, and then learn the corresponding CAD, it is easier to learn and master.
