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
