Simplify Geometry is a tool used for removal of intervals and external referencing rules for horizontal and vertical geometries.

You can access this tool from the following:

The tool reduces the rules to the defining geometry. In other words, it removes rules and relationships from other elements, which includes snap rules, offset rules, and intervals from other elements that constructed the geometry. After running the tool, the geometry reflects the ruling of geometry that is imported in from ALG, GPK, FIL, and LANDXML.

This tool should be used with caution, since the referencing rules that constructed the geometry are removed. This means the original design intent no longer exists and the geometry will no longer update since it no longer monitors these elements for changes.
