kte kind of door do exist!

i was asked,laughed and questioned  in my crit session just on how i draw my door in autocad floor plan. and today, i saw a specification on a blackbox floor plan drew the door i draw on my plan!!so am i wrong on the way i draw them??am i?i hope i'm not. i feel so bad when i've been critised heavily for the way i draw my door rather than my design.i hope they could have see more into the design rather than the drawing convention (which is technically not wrong,but just they dont usually see).
