1, drawing type: understand the types and composition of drawings, such as plan, sectional view, detailed drawing, assembly drawing, standard parts drawing, etc.
2. Drawing marking: Understand various marking symbols on drawings, including dimension marking, tolerance marking, surface roughness marking, machining symbols, etc.
3. Coordinate system: Understand the coordinate system in the drawing and how to locate the figure and measure the size according to the coordinate system.
4. axonometric drawing: master the representation method of three-dimensional graphics, including axonometric drawing and perspective drawing.
5. Drawing specifications: familiar with drawing specifications, such as drawing scale, font size, line thickness, symbol usage, etc.
6. Picture reading skills: Good picture reading skills, including looking at the whole before looking at the parts, looking at the text before looking at the graphics, and imagining while watching.
7. Repeated review: carefully review the drawings repeatedly to ensure the understanding and mastery of the contents of the drawings.
The following are several steps to learn drawing design:
1, learn basic knowledge: first, you need to learn basic knowledge, including graphics, engineering drawing, CAD software, etc. You can learn through courses, textbooks and online resources.
2. Practical operation: After theoretical study, practical operation is needed to improve skills by drawing different types of drawings, such as plane layout, mechanical parts drawings, assembly drawings, etc.
3. Participate in actual projects: participate in actual projects and learn experience and skills from them. You can find relevant industries, enterprises or studios to apply for internships or part-time jobs.
4. Learn professional software: learn professional drawing software, such as AutoCAD, Solidworks, Creo, etc. , and master its basic operation and application skills.
5. Continuous self-improvement: always pay attention to the latest technology and development trends, actively participate in industry conferences and training courses, and constantly update their knowledge and skills.
