Model.hm_wadlinessetentities_bycollection#

Model.hm_wadlinessetentities_bycollection(frontEntities, rearEntities)#

Sets the entities used for a WAD lines analysis.

Parameters:

  • frontEntities (Collection) – The collection containing the front entities of the vehicle (bumper, bonnet, fenders). Valid entities are elements, surfaces and components (elements take priority over surfaces).

  • rearEntities (Collection) – The collection containing the rear entities of the vehicle (windshield, a-pillars). Valid entities are elements, surfaces and components (elements take priority over surfaces).

Returns:
