    Alignments – What can they do?

    So we have all used alignments before, they only do surface profiles and pipeline routes right? Wrong! You can also use them to generate information in conjunction with the points features.

    If you look in the points menu, there is an entire section dedicated to generating points from the alignment.

    Station/Offset - Creates points that are offset from the stations on the alignment.

    Divide alignment - Creates points that are a specified distance apart along an alignment.

    Measure Alignment - Creates points at equally spaced intervals along an alignment.

    At Alignment geometry - Creates a point at a geometry point along an alignment.

    Radial or Perpendicular - Creates a point on the alignment that is radial or perpendicular to a specified point.

    Import from file - Creates points along an alignment by importing from a file that contains stations, offsets and elevation data.

    Profile geometry points - Creates points along the alignment from geometry points from the profile view.

     

    For this example let’s check out the measure alignment option seen in the image below, this allows us to generate points at intervals along the alignment. Give it a try, from here, as with many Autodesk platforms, check the command line for the next steps, it will ask you to select the alignment, then the chainage you want to start and end at, specify an offset, an interval and a point name, it will also ask you for a reference profile so make sure you have one drawn. Once done your points will appear.

    Your points may be left without labels, you will have to add a label style to these in point group properties but it’s an easy way to gather useful information quickly, select a point and the right click menu contains the button for selecting the properties.

    As with any points, they can also be easily exported from within the prospector, find the point group, right click and export a text file. If you browse to your text file you should now see something like the document below with all the information you need quickly and easily.
