Engineering Graphics is a technical fundamental course of mechanical engineering and non-mechanical engineering, which concerns theory and application of engineering drawing and design. It mainly focuses on introducing orthographic projection theory and application, China National GB and ISO standards, 2D representations, and 3D digital modeling technology etc. The objectives of this course are to cultivate student skills of reading and creating engineering drawing, enhance their capability of visualization and modeling, in addition, aim to foster practical ability of using advanced design method and three-dimensional software to finish required design projects, one semester 2 or 3 credits.

     The main knowledge points are as the following:

1. Projection concepts/methods/classification, and orthographic projection of points, lines and planes;
2. Basic solids and their three principal views;
3. Intersection between plane and solids/between solids;
4. Modeling, writing, reading, dimensioning for objects;
5. Axonometric drawing (isometric and cabinet) of objects;
6. All commonly-used representations for workpieces;
7. Screw thread structure, standard threaded, non-thread fasteners, and commonly-used parts;
8. Part modeling, geometric and dimension tolerance labeling on 3D model, and detail drawing reading relevant knowledge points;
9. Assembly modeling (bottom-up and top-down design cases) and drawing. 

    After studying this course, you will be able to:

1. Understand orthographic projection theory completely;
2. Grasp fundamental drawing technology;
3. Communicate with your partner through free-hand sketching;
4. Operate 3D design software (Inventor professional) skillfully, such as creating models and drawings for single part and assembly;
5. Read technical drawings;
6. Carry out some innovative design based on top-down design approach considering sustainable design principle.
7. Note: all knowledge points have been linked closely, and CADD has been integrated into the teaching content and process seamlessly in each chapter. 

After studying this course, you will be able to:

1.  Understand projection theory, especially orthographic projection theory;
2.  Master the basic technology and standards of engineering graphics;
3.  Communicate with partners through hand sketching and tool drawing;
4.  Use 3D design software (Inventor Professional Edition) skillfully to create models and drawings for parts and components;
5.  It is very pleasant to know how to transform the design idea into a 3D model according to the multi-body top-down design method.

1. Know how to operate computer and search internet to get software you want.
2. Understand how to use mouse left button, right button, and middle wheel skillfully.

Q: What needs to be done in advance? 

A: You need a desktop or a laptop and install software Inventor professional 2023 or 2024, and make sure the software works well. 

Q: Where can I download free software Inventor professional? 

A: You can download free software Inventor from the website https://www.autodesk.com.cn, but you'd better register and login in through your educational email box, or non-educational email box, but you have to prove you are a registered student. Furthermore, if you want to download and install the software successfully, you should follow the instruction of the website to validate you are a student or educator. 

Q: If I am not a university student, how to get free software Inventor? 

A:  One way, you can download a cracked down one, but I have to remind of you, the software copyright is preserved. Then the second way, you can leave message to me, I will try to help you solve your problem.

Q: How to consult you if I have some questions?

A: You can leave messages in forum, if necessary you can take screenshot to describe your question.  

Q: Sometimes the videos are not very clear, How to solve the problem?

A: I suggest you watch the videos in full screen on your computers, such as desktop, laptop, surface, or iPad, it is really better than watching on your mobile phone.
