I've got the problem when drawing this part. I've learned by myself. Appreciate your help!
Please post what you have done so far and what you are having an issue with. Only couple of areas I see that could be confusing.
Here's what I've done! Could you give me an advice
Looks perfect and I would have it exact same way.
Except for your second sketch being underdefined, you modeled it well. In the screen shot below I have isolated why you needed to use contours in your extruded cut (a common issue when using the rubber band method of sketching lines).
Another problem I see (not yours but with the original sketch) is the 25 dimension off the 30 degree angle is actually almost 26 (or if you make it 25 the angle is approximately 29 degrees). Not sure if this is bad rounding errors or we are all missing something...
I only did a quick check (mainly for the method) as I was short on time. Glad you bought up the other issues.
I really don't know my sketch underdefined. Can you show me the good way to check what sketches underdefined if a Part has many features and I forgot to check RELATIONS before making boss!
The easiest way to check if a sketch is underdefined is to look for the ( - ) in front of the sketch name; it indicates the sketch is underdefined.
Also when you are editing a sketch, look in the lower right hand corner of the SolidWorks window. Tells you what sketch you are editing and whether it is fully or under defined.
If I have a part with many features (or I need to check many parts) it'll take time for me to click every feature!!! Do you have any sugggestion?

The easiest way to go about this is to make sure the sketch is fully defined as you complete the sketch. Develop good habits now and it will serve you well as your skill improves. It is one of the most fundamental Best Practices to make your sketches fully defined. It is easiest to do this as you go.
Thanks @Dennis Dohogne
I'm just wondering if I were a teacher how could I check "UNDERDEFINED" of all homework ?

One easy way is macro. Second option is to use Design Checker to compare the master model with the student files.
Finally teach student to make fully defined sketches like Dennis and for beginners, tell them to use this option
I think Dennis and Deepak answered your question quite well.
