Contour Smoothing

I just finished watching a new Autodesk webcast and learned a few things about surface editing. I'm sure a large number of you experience the short choppy or jagged lines in your contours when doing grading. There are many methods on how to make contours smoother but I'm going to show you what I saw today that might help you.


First select the surface you wish to edit. Then in the ribbon, select Edit Surface. Click on the small pulls down and selects smooth surface option. The smooth surface dialog box will appear. Now click on the Select output region row, a small icon should appear on the far right. Click on it, and look at your command line. You should see this:

Select region or [rEctangle/pOlygon/Surface]:

Select O to create a polygon around the area you wish to revise. Type C to close your polygon. The smooth surface dialog box should pop up. Change the X & Y grid spacing to a small # from 1-5 like shown below. Once you hit ok, the contour should be smooth. Hopefully this information will come in handy for your grading design process.

  3. Too easy to use smoothing to mask surface errors. The rule around me is no smoothing.
