Specifies whether the tap direction is perpendicular (Radial) () or parallel (Axial) () to the vector of the part port selected as the reference position. This option is available only when you select an end feature (cap, blind flange, and so forth) or a turn feature (such as an elbow or pipe bend) as the component. For straight pipes and tubes, and the straight sections of a pipe bend, the orientation is always set to perpendicular. For pipe bends, the tap is always placed perpendicular to the flow direction throughout the turn.
A - Perpendicular (Radial)
B - Parallel (Axial)
