From which direction is AutoCAD measuring angles?

from positive x axis and go around it in counterclockwise whick get positve axis of y then negative aixs of x then negative axis of y generally from right to left

starts from horizontal (X-axis) that has direction to the right - positive angles are towards Y-axis (counterclockwise), negative angles are clockwise

horizontally from left to right  0 Degree 

IF WE GIVE THE ANGLE IN POSITIVE FOR EXAMPLE 30 DEGREE THEN THE ANGLE MEASURES IN ANTICLOCKWISE BUT IF WE GIVE -30 DEGREE ANGLE THEN THE ANGLE MEASURES IN CLOCKWISE DIRECTION
