Problem with the insertion of symbols and the depth of a line

Hello i want to add on my scroll (draft) some tollerance symbols . For example the symmetry symbol or symbol like the trapezius and so on.

Does exist a command like the "Symbol" in Word?

Another question is about the depth of a line. Always considering the M.W. does exist a command with which i can increase the depth (thickness) of the line?

Thank you.
