Do you ever need to isolate a range of contours at an increment for a plan view? Say elevations 90 - 95 shown at 0.5 ft intervals? Autodesk® Civil 3D® has a way to do this through setting up a user contour analysis, but requires you to manually enter each contour elevation, color, linetype, and lineweight while also requiring a surface style setup for viewing the analysis. This app helps to alleviate the cumbersome workflow by quickly applying the desired results.
