Delete a portion of the 2D mesh

LB
I have a completed 2D model and would like to delete a portion of the 2D mesh. I used excel and GIS to edit the 2D Area Outlines Area table to adjust the 2D boundary, but all of the cell centers and breaklines remain in the area of the model that was removed. Is there a way to efficiently remove these cell centers and breaklines? I only see how to delete them individually.

If you select the 2D flow area with a single left click you should see a "remove all cell points outside perimeter" option. Selecting that will remove the points and having breaklines that run past the boundary shouldn't be an problem.
