Washington State Police Forensic Scientist Trevor Allen presented at the 2018 ACSR Tacoma WA Conference on working with trajectories in Cyclone software: Mr Allen has recorded a summary of how he creates demonstrative exhibits using Leica Cyclone software to extend ballistic trajectories from a vehicle: Defect height, (point to unbounded surface (patch) under vehicle) measures zenith and azimuth angles of the trajectory and place an cone on the trajectory rod.
