Fire Investigation Tools V10.6

Introduction The FARO CAD Zone diagram program has the tools you need to create a 2D and 3D fire scene diagram with data collected from hand measurements, a total station, or your laser scanner. Mapping the fire damage of a room or building is a challenging job. Using a laser scanner can greatly reduce the time on-scene while still collecting essential data needed for a thorough fire investigation. Diagrams play a big role in fire investigation and the tools found in the FARO CAD Zone diagram program makes that job faster and easier. Diagram and analyze the scene with your measured data, creating:

2D wall elevation views

Show fire damage to furniture and other symbols

Show char and smoke patterns

Show char depth topography

Show the spread of the heat or flame

Show the fire area and point of origin

Insert photos

Create site and floor plans Once you’ve completed your real world scale diagram, you can print or create a .pdf file of your work.

Wall Elevation Builder Quickly create 2D wall elevation views of a room from your point cloud data with the Wall Elevation Builder tool. Draw on a wall in the point cloud using points, lines, arcs, circles, and curves and then project them onto a 2D wall elevation in the diagram.

NOTE: Before you can use the Wall Elevation Builder tool you need to have the following:

A 3D wall created with the 3D Builder tool from a line or continuous line.

Points, lines, arcs, curves, or circle data that has been drawn on the wall by tracing over the point cloud.

Potentially doors and windows place using the Doors/Windows tool.

1. Trace a wall or walls in the point cloud. a. We want the walls to be flat on the ground. b. In CZ Point Cloud turn 2D Trace mode ON. c. Draw a line around the point cloud.

2. Turn the outline into 3D walls. a. Select the wall line. b. Click on the 3D Builder tool. c. Set a Wall Height.

3. Draw on the wall in the point cloud using the CZ Point Cloud tools.

4. Click on the Wall Elevation Builder tool located in EZ Tools.

5. You will be prompted to select the 3D data to project to the wall. Select by clicking on the data or dragging a window around the data. Remember you can add to the data by making multiple selections while holding down the Shift key. In this example curves and continuous lines are used to trace char and smoke patterns. Once selected, hit the Next button.

10. Add text, dimensions, and patterns to finish the view. Repeat for other walls.

11. The view in 3D without the point cloud.

Char Depth Trace the char patterns in the point cloud and label different char depths. In this example the char depths were

measured on exposed ceiling joists. Place depth labels using the Text tool. Select the text and use the Blot

Out tool to hide the line behind it.

Fire Investigation Symbols There are thousands of symbols to choose from in the Fire, Insurance, Crime, and Crash Zone programs. Everything you’ll need from vehicles, furniture, fixtures, and evidence placard symbols can all be found in the Symbol Manager. A special group of fire investigation symbols can be found in the “Fire Inv” folder in the Fire and Investigation symbol groups. In the Crime/Crash Zone under the Crime symbols group.
