Feature Line Constraints.

Feature Line Constraints.

Include a lock symbol checkbox next to each Feature Line parameter on the Feature Line editor. Often, a Feature Line comes to a point that is fixed, such as an existing structure, or has a minimum or maximum slope.


For instance, set a slope for a feature line and lock the slope values for all but the last segment. Set the elevation of the last point (i.e. a drain inlet) and lock it. Adjust the elevation of the first point. The locked segments retain their slope, and the last segment adjusts it's slope to match the last endpoint.


Additionally, add a constraint for maintaining constant grade between points, such as point 8 to 12. Perhaps this could be done by linking to cells above and below.
