Basic knowledge and operation of AUTOCAD/cad
Understand the development process of AutoCAD and its application in practical work, and know its application scope and help. Students are required to establish concepts related to AutoCAD.
1 introduction. AUTOCAD working interface
2. Set up CAD drawing environment
3. Management of graphic files in 3.CAD
4. Control of drawing accuracy
5. Set the size of the drawing.
6. Understand the world coordinate system and user coordinate system.
7. Set the user coordinate UCS option.
8. Set the object capture function
AUTOCAD/cad 2D Drawing and Editing
In cad, any graphic is composed of some basic graphic elements, such as lines, circles, arcs, rectangles, polygons and characters. Mastering the drawing methods of these basic geometric elements is an important basis for learning CAD software.
Drawing method of graphics
Master the drawing method of AutoCAD graphics, and master straight line, multi-line, multi-segment line, regular polygon, rectangle, arc, circle, ring, spline curve and ellipse; Familiar with other commands.
Graphic editing
Master the commands of deleting, copying, mirroring, offsetting, patterning, moving, rotating, scaling, stretching, lengthening, trimming, extending, breaking, merging, chamfering, fillet, polyline, spline and multiline editing, decomposition and feature matching.
AUTOCAD/cad Advanced 2D Drawing and Editing
CAD mechanical cases: CAD nut three views, CAD flange two views, CAD bottom plate two views, CAD two-dimensional assembly drawing, etc.

2.CAD construction line, multi-line use;
3. How to use 3. CAD polyline
4.CAD equidistant segmentation and equal division;
5.5 Making and inserting skills. CAD block
6.CAD creates words and tables;
7.CAD query area and area coverage.
AUTOCAD/cad isometric drawing
The axonometric drawing such as cad is a two-dimensional figure reflecting the three-dimensional shape of an object, which is full of three-dimensional sense and can help people understand the product structure more quickly and clearly. Drawing an axonometric drawing of a part is done on a two-dimensional plane, which is more concise and convenient than a three-dimensional drawing.
1. Understand the CAD axonometric drawing;
2. Set the axonometric mode;
3. Skills and precautions for drawing axonometric drawings;
4. Draw an axonometric drawing.
AUTOCAD/cad three-dimensional drawing
CAD three-dimensional graphics are more and more widely used in engineering drawing design and drawing. AUTOCAD provides powerful three-dimensional graphics drawing function, * * three-dimensional space, which can intuitively express the product design effect, observe the model from any angle as needed, create sections and two-dimensional graphics, and dynamically observe.
1.Classification of AutoCAD 3D models
2. Three-dimensional coordinate system
Set view
4. How to create an entity
5. How to create an entity by * * 2D graphics?
6. Modify, adjust and watch the 3D model.
AUTOCAD/cad text tables and labels
As an important part of engineering drawings, dimensioning should also be standardized. A complete dimension is mainly composed of dimension text, dimension line, dimension arrow, dimension line, center mark and leader. Marking the correct size should not only meet its own integrity and standardization, but also be set correctly.
1. Text style and editing
2. Text comments
3. Form
4. Marking rules and size composition
5. Size style
6. Lead label
AUTOCAD layout and printing
After creating a drawing, it is usually printed on a drawing, or an electronic drawing can be generated for access from the Internet. A printed drawing can contain a single view of the drawing or a more complex arrangement of views. According to different needs, you can print one or more viewports, or set options to determine the layout of printed content and images on the graphics.
1.cad model space and layout space;
2.cad uses layout wizard to create layout;
3.cad uses floating window to observe graphics;
4.4.cad method of publishing graphics to web pages.
Today, Bian Xiao collected AutoCAD teaching videos, rich materials and e-books, which made CAD a little small!
