V5.50 -- October 1996

TNT V5.5 adds a powerful Region of Interest selection feature. You can define a region and use it to select elements from other project materials that share at least some of the same spatial extent. In this example, a Public Lands vector object was used to identify two regions. Those regions were applied to a soils vector object to create a soils region.

The soils region polygons fall completely inside the area defined by the original Public Lands region. In the next step, the new soils region is applied to a hydrology vector object to get selected hydrology line elements, clipping them at the boundaries of the soils polygons.
