It is crucial for a reliable calculation of the 3D pipeline network, that you have entered valid data into all the corresponding altitude/depth fields of the section and node category:
Pipe depth in the upstream manhole (from cover to pipe bottom) (SECTION.OBJ_FromNodeDepth)
Pipe bottom altitude (above sea level) in the upstream manhole (SECTION.OBJ_FromNodeInvert)
Pipe depth in the downstream manhole (from cover to pipe bottom) (SECTION.OBJ_ToNodeDepth)
Pipe bottom altitude (above sea level) in the downstream manhole (SECTION.OBJ_ToNodeInvert)
Manhole cover altitude above sea level (Z-Coordinate) (NODE.OBJ_Shape_WKT_Z)
Depth of the upstream/downstream manhole (from cover to bottom) (NODE.OBJ_DepthToInvert)
Bottom altitude above sea level of the upstream/downstream manhole (NODE.OBJ_NodeInvert)
The sketch below illustrates the meaning of these fields:

Legend:
Green = values to be provided by engineers/water authorities
Brown = values to be measured by the operator or provided by engineers/water authorities
Blue = values to be measured by the operator
Red = values calculated by WinCanVX hitting the button Tools > Calculate Invert Levels
Running 3D measurement for main pipes

5.) Confirm the last step hitting the green START button for 3D measurement. Also make sure the red video recording button is activated.
...
6.) Enter the START observation, drive the camera through the main pipe and enter any further observations/defects. Besides the video clip recording the software does a stepwise recording of the current camera position (X/Y/Z) from the beginning to the end of the inspection.
...
Confirm this message and get the lateral connections created at the corresponding position hitting the command AutoCreate Laterals (1):
...
The column Lateral (2) then shows the satellite icons. Double-clicking on the desired icon will switch to the category Laterals and highlight the satellite record you want to inspect:
Continue driving backward inside the main section until you reach the position of the next lateral and repeat the steps 1 to 7.
Continue driving backward inside the main section. A message tells the user when the meter counter has reached the value 0 and the camera crawler is back at
...
Switch on the SAT camera and set the SAT distance counter to 0.00 m. This again will launch the 3D-measurement wizard in a separate panel. Follow carefully all the given steps:
1.) Verify the connection point (e.g. downstream node) where you stopped the camera and set the measurement direction as illustrated in the wizard panel:
...
2.) The next step asks you to set the start direction of the measurement. Move the pointer via Drag and Drop and follow the red arrow depicted in Map to verify the correct direction in relation to the DXF-plot:
...
3.) Move to the position where the lateral is connected to the main pipe and set the view direction of the camera as illustrated in the wizard panel:
4.) The next step tells you to set camera OFFSET and PRESET:
OFFSET: distance between camera head and the beginning of the lateral pipe
PRESET: distance between camera head and start point of the inspection
5.) Run the 3D-measurement before you push the camera head into the lateral pipe (2).
6.) Enter the START observation, push the camera through the lateral pipe and continue with the damage survey.
7.) Enter the END observation as soon as the camera has reached the pipe end and stop the 3D measurement. Drag the satellite camera out of the lateral pipe until it has reached the start position:
...
Hitting the arrow icon in the symbol bar gets you back to the corresponding main section.
Continue driving backward inside the main section until you reach the position of the next lateral and repeat the steps 1 to 7.
A final message informs the user the camera crawler has reached the beginning of the main pipe:
