IfcOneDirectionRepeatFactor

Definition from ISO/CD 10303-46:1992: A one time repeat factor is a vector used in the fill area style hatching and fill area style tiles entities for determining the origin of the repeated hatch line relative to the origin of the previous hatch line, Given the initial position of any hatch line, the one direction repeat factor determines two new positions according to the equation:

> I + k * R k X{-1,1}

> NOTE: Corresponding STEP name: one_direction_repeat_factor. Please refer to ISO/IS 10303-46:1994, p. 112 for the final definition of the formal standard.

> HISTORY: New entity in Release IFC2x 2nd Edition.
