Slightly tangential but related - here’s a good example where it’s very nice to rebuild with a Curvature calculated point spacing/parameterization:
I’m rebuilding these two curves - in this case these are planar intersections of laser scanned data, so the intersections curves themselves are very dense, and evenly so. The shape of the curves is best done by a non uniform point distribution, so in this case, having a “Curvature” option in VSR yields a nice result:
If I had a version of this curve that had the right point distribution - more at the top, less at the bottom - but too many points, using the “Original” option would have yielded a likely similar result - it’s really good to have all three options - MOST of the time “arc length” is the right choice, the other two options really come in handy from time to time.
