Model.hm_wadlinessetaxes#

Model.hm_wadlinessetaxes(origin, forwardvec, leftvec)#

Sets the origin and coordinate axes for a WAD lines analysis.

Parameters:

  • origin (hwTriple) – The list of objects defining the X, Y and Z coordinates of the origin. Must be at the vehicle centerline (default 0,0,0).

  • forwardvec (hwTriple) – The list of objects defining the vector pointing toward the front of the vehicle (default 1,0,0).

  • leftvec (hwTriple) – The list of objects defining the vector pointing toward the left side of the vehicle (default 0,1,0).

Returns:
