Bergen County, NJ Fatal Crash Unit Appreciates CZ Point Cloud

For more than 12 years, the Fatal Accident Investigation Unit (FAIU) of the Bergen County, New Jersey, Prosecutor’s Office used The CAD Zone’s Crime Zone software to document crime and crash scenes. When the agency acquired a Leica ScanStation C-10 laser scanner the investigators tried using the point cloud software that was included with the scanner. They found that they could easily scan a scene, but they struggled with creating courtroom-quality diagrams from the resulting point clouds.

Detective Andrew Rich, a 14 year veteran of the Bergen County FAIU (now retired), evaluated The CAD Zone’s CZ Point Cloud software and he quickly determined it was ideal for creating crime and crash scene diagrams from scanned data. He appreciated the many tools included in CZ Point Cloud that are specifically for generating 2D diagrams – which are critical for most investigations. Only CZ Point Cloud makes it easy to work within a point cloud and accurately select the evidence points you need to build both 2D and 3D diagrams.

Use Pre-drawn Symbols For Faster Diagrams

If you are a Crash Scene Investigator, chances are you have better things to do with your time than spend hours and hours creating drawings of crash scenes. One way to really save on drawing time is to use pre-drawn symbols for commonly found objects.  Instead of trying to draw that vehicle or sign found at the scene, just select the pre-drawn symbol and drag it into place.

General purpose drawing programs may have pre-drawn symbols of furniture or trees, but they will not have many items found at a crash scene, such as vehicles, bodies, signs, or weapons. To get these types of symbols, you need a software program that is specifically for drawing crash scenes.The Crash Zone, crash scene diagramming software published by The CAD Zone, Inc., has thousands of pre-drawn symbols that are ready for you to place in all of your 2D and 3D diagrams. You can easily change any symbol’s rotation, size, and color as you place it in the diagram. Symbols can be placed at an approximate location in the drawing or snapped to an exact data point.

Crash and Crime Scene Diagrams Are Obsolete – Right?

Investigators today are being bombarded with talk of point clouds, fly-throughs, animations, orthrectified images, and simulations. Since a crash or crime scene can just be “scanned” and recorded as a point cloud, some sales people will say that’s all an investigator needs to present in court. Just present the jury with a fly-through of the point cloud or show them a simulation and there is no need to create those old-fashioned diagrams any longer, right?


Upgrade Your Court Presentations With Animation

If you’ve ever wondered if it’s worth the additional expense to upgrade your crash scene diagramming software, one expert responds, “Absolutely.” That expert is Bobby Jones of Bobby Jones Reconstruction of Knoxville, Tenn. For more than 25 years, Jones has been a trained crash reconstructionist and crime scene investigator, providing his expertise to private law firms, major trucking firms, insurance and government agencies, County Sheriffs, the State of Tennessee, and to prosecution and criminal defense clients.

The Crash Zone Includes Easy-to-Use Animation Tools

A major reason that Jones suggests upgrading your diagramming software is to get the animation features now offered in some software. Jones has been a longtime user of The Crash Zone, diagramming software from The CAD Zone, Inc. ( ) of Beaverton, Oregon. The Crash Zone is widely used among law enforcement professionals and crash scene investigators. It allows users to create realistic 2D and 3D diagrams of scenes. The latest version of The Crash Zone also features the ability to quickly create 2D and 3D animations of objects that are based on your exact measurements.
