The shadow indicates that the pipeline is not parallel to the quadrant axes but forms a certain angle; the shadow auxiliary lines show that the pipeline lies in different planes: XY, XZ, and YZ.
What does the value 760 325 234 next to the shadow represent?
It might be the value of the shadow side length, serving as a guide for construction.
The 760 pipeline is at a north-easterly distance
The shadow representation shows that the pipeline is not parallel to the quadrant axes, but is offset at a certain angle; the shadow guides indicate that the pipeline is represented in different planes such as XY, XZ, and YZ, which facilitates differentiation.
