1 Intersection 2D Demo 1) Open the Crash Zone or Crime Zone diagram program. 2) Click on to open the CZ Point Cloud tool. 3) Click on 3D/Cloud Preferences. a) Set the Cloud File Units (Feet or Meters). b) These units should match the Export Units set Scene. c) Feet for this example. d) Un-Check Show Ground Plane (if checked). 4) Click on Load Point Cloud to load the.czp file from Scene. Open Intersection_Demo.czp NOTE: This example was previously saved with the ground level adjusted. For this example this step is not necessary but will be helpful for future work. 5) Ground Level Adjust to adjust the point cloud so the lowest point is at the ground plane (elevation of 0). The altimeter on the scanner sets the overall point cloud height. For drawing purposes it will be easier to have zero elevation. a) Click on Display Tools. b) Click on Elevation Adjust. c) Click on OK to make the adjustment. 6) Set the view to Top Down. 7) Turn 2D Trace Mode ON. NOTE: Turning on 2D Trace Mode means that connecting to points in the CZ Point Cloud tool will generate on 2D data, giving every point snapped to a zero elevation.

2 8) Maximize Viewing When working with point clouds in CZ, it is best to view both CZ and the Point Cloud tool at the same time. If two (2) monitors are available, this can be done by placing CZ full screen on the left monitor and CZ Point Tool full screen on the right. When dual monitors are not an option: a) Move the mouse to the title bar of CZ. b) Click and hold the left mouse button. c) Drag the cursor to the left edge of the computer s screen until a ripple effect occurs at the cursor. Ripple effect appears d) Release the cursor. e) Move the mouse to the title bar of CZ Point Cloud. f) Click and hold the left mouse button. g) Drag the cursor to the right edge of the computer s screen until a ripple effect occurs at the cursor. h) Release the cursor. 9) Before you start drawing in the point cloud it is a good idea to set the line type properties to a bright color and heavy line thickness so that it stands out from the point cloud. To do this: a) In the Tool Zone, click located under Properties b) Choose a color from the Color Palette c) Click d) Choose either 3 Medium or 5 Heavy

3 Line thickness options Road Edges 10) Draw the road edges using the single line, arc, and curve tools. a) In the 2D drawing window click on the Single Line tool found in the Draw tool group. b) Snap to Point 1 and then Point 2 in the point cloud.

4 ERROR HANDLING a) While drawing a continuous line, curve, or arc you can UNDO the last point selection by pressing the ESC key. b) If you complete the placement of an object in error, you can click on the UNDO tool in the diagram program. c) You can ERASE unwanted objects in the drawing by selecting them and pressing the DEL key. c) In the 2D drawing window click on the 3pt Arc tool found in the Draw tool group. d) Snap to Point 2, Point 3, and Point 4 in the point cloud. Snap to Pt.2 at the end of the last line placed in the diagram. NOTE: You can only snap to cloud points in the CZ Point Cloud tool. Snap to actual drawing entities in the 2D drawing window.

5 e) Click on the Single Line tool and snap to Point 4 and then Point 5. 11) Draw the road edges in Area A and Area B using the line and arc tools.

6 12) In Area C draw the road edge using the Curve tool. a) Click on the Curve tool found in the Draw tool group. b) Click on Pt.16 c) Create a smooth curve by clicking on points in-between the last point. d) Click on points a, b, c, and d. e) Finish the curve by clicking on Pt.17 and pressing the ENTER key. 13) Draw the double yellow centerline. a) Draw a Single Line starting from the center of the double yellow line Pt.1 to Pt.2. b) Click on the line just drawn in the diagram to select it. c) Click on the Reset Properties tool.

7 d) With the line still selected, click on the Line Type properties button, then click on Center Lines, and then the Double Solid line type. Curbing (Stop Bar) 14) Use the Continuous Line to trace the outline of the stop bar. When connecting the last point to the first point do it in the 2D drawing window. Click on the first point (Pt.1) and press Enter to finish the line. NOTE: You can only snap to cloud points in the CZ Point Cloud tool. Snap to actual drawing entities in the 2D drawing window.

8 Symbols 15) Quickly draw the outline of the STOP curbing using the Continuous Line. 16) Place the Symbol for the STOP curbing (road mark). a) Open up the Crash symbols group. b) Select the Stop symbol. Traffic Ctrl>Curbing>Stop

9 c)click on the Symbol Color tool to change the STOP symbol to red. d) Click the first symbol point (1). Rotate and click the final point (2).

13 NOTE: If you don t like the results of the Hide Colors tool you can click on the Undo Last Display Tool from the Point Display menu. You can also re-load the point cloud file. c) Use the Curve tool to draw the skid marks. NOTE: Use the Density: and Pt Size: sliders to adjust point cloud display to for the best view.

14 d) Select the skid mark lines and change them to a skid mark line type. The drawing can now be completed without the point cloud data. 18) Close the CZ Point Cloud tool. Click on the X upper right corner of the CZ Point Cloud window. 19) Maximize the diagram program in the.
