Elevating Utility Lines and Creating Trench Bottom Surfaces

Here is a video that shows how to quickly elevate 2D lines for the inverts of utility lines and then to use the 3D lines as a basis to create the linework and surface models for the bottom of a utility trench.

As a follow on to this video - I was asked how to do this from an imported LandXML file also - In the following video we show how to

  • Draw 2D polylines between pipe ends to create pipe centerlines
  • How to use Advanced Select to select pipes of the same diameter - so you can relayer them by size
  • How to elevate those lines using the pipe data to Pipe Centerline
  • How to adjust the line elevations to base of pipe or trench bottom (allowing for bedding material)

From there the process s the same as the first video above

This is helpful. I normally elevate utility lines and look for conflicts from flow line to flow line. I have a PM that measures off of the plan sheet sectional view. I’m not sure how accurate that is - the view shows the pipe cross perpendicular one above and one below.
