Specifies the turn radius that the software will use for turns while routing as a multiplier function of the duct dimension in the plane of the turn. The dimension used is the diameter for round cross section, the width dimension, or the depth dimension, depending upon the plane of the turn. If you change the bend radius multiplier, the software automatically changes the throat radius value.
The list displays the last five values in numeric order. If this is the first time in the session file, the Bend Radius Multiplier is the default from the active specification.
