Model.hm_wadlinessetparameters#

Model.hm_wadlinessetparameters(side_angle, front_angle, spacing=0, rear_reference_radius=0, reference_resolution=0, upper_bumper_angle=0, lower_bumper_angle=0, corner_angle=0)#

Sets basic parameters for a WAD lines analysis.

Parameters:

  • side_angle (double) – The angle used to determine the side reference line. (Default=45.0)

  • front_angle (double) – The angle used to determine the front reference line. (Default=50.0)

  • spacing (double) – The distance between section cuts used to determine the WAD lines and reference lines. (Default=100.0)

  • rear_reference_radius (double) – The size of the ball rolled along the windshield to find the rear reference line. (Default=100.0)

  • reference_resolution (double) – The spacing between cross-sections used to determine the reference lines. (Default=:python:spacing/2)

  • upper_bumper_angle (double) – The angle used to determine the upper bumper reference line. (Default=20.0)

  • lower_bumper_angle (double) – The angle used to determine the lower bumper reference line. (Default=25.0)

  • corner_angle (double) – The angle used to determine the corner reference lines. (Default=60.0)

Returns:
