Import elevation data in the form of pipeline profile represented by a CAD polyline

Recently I was tasked with a water supply project involving some water hammer calculations and had some trouble building the model.

I have the plane layout of the pipeline and the elevation data in the form of  pipeline profile represented by a CAD polyline, as shown in the images below. Please note the numerical values are not organized in a chart so I can't just pull it out of the DXF file.

I can use the ModelBuilder to import the plane layout of the pipeline, but I can't find a way to import the elevation data. It seems the TRex tool does not recognize data in such form, so is there some other way to do this?

Looking forward to your help, thank you!

  • Hello Renbo, 

    To import the elevation data using TRex tool you either need to have DXF contour data or DXF point data , or data in formats like Landxml or shapefile. 

    The image shows station values, but TRex will not just pull elevations out of a DXF file, you seem to have contours in your drawing which should have elevation data in z co-ords, please check that. More information on input data for elevations is provided below, please go through it. 

    Using Terrain Extractor (Trex)
