Merge Existing With Design
This command allows you to merge the existing surface with design
surface within perimeter polylines. The resulting merged surface can be
saved to update either the Existing or Design surfaces. The program
prompts for inclusion and exclusion perimeter polylines. These
polylines must be closed. The merge will be applied inside the
inclusion perimeters and not inside the exclusion perimeters. The
exclusion perimeters are optional.
For example, if a portion of the site is completed, you can update the
existing surface to match the design for the completed area. First,
draw a closed polyline around the completed area. Then run Merge
Existing With Design and choose the merge results target as Existing.
Then select the perimeter polyline.
Prerequisite: existing and design surfaces and an inclusion
perimeter polyline
