I just posted a new video on how to use SQL in Manifold 9 to create multi-ring, non-overlapping buffers. In this example, larger buffers are trimmed to the edges of the smaller buffers.

The video is 16 minutes long, but I show you the answer at the beginning. If you want, you can watch the rest of the video to see the logic in structuring the SQL. It not only gives you a very useful tool for your GIS toolbox, but helps you think about the logic of how to create a more sophisticated SQL query, one step at a time.

You can see the video here.
