    1. The problem statement, all variables and given/known data
    There are 3 big mistakes in this drawing and I would really appreciate if anyone could help me find out exactly what those are. Thank you.


    2. Relevant equations
    Since I am new to engineering drawings, I can only make assumptions and would really appreciate if I am corrected rather than mocked.


    3. The attempt at a solution
    As far as I am concerned
    1- The vertical line should be of a different format as it would not allow rotation if they are the same.
    2- It is unclear what the dimensions are (whether they are in millimeters or centimeters etc)
    3- The angles should have some negative deviations as well in addition to positive ones (if this one is incorrect, kindly explain it to me why)
    4- (=210=) Is this a valid format as I am pretty sure it is not.

    Only had a quick look but:

    1) the length is 420 on the drawing but "L=364" on the Dimensions block at the bottom.
    2) I've not seen =210= used before but if it's a valid notation why isn't it =420= just below?
    3) Date/issue/version number?
