I only have an imported TIN for the existing surface. It has a voided region where some standing water is. Field notes verify that its onlya few inches deep.
I need to remove the voided area so more corridor can interpolate.
1) I have tried deleting the points and tin lines that are all associated with the void. that just spreads and creates multiple little voids
2) I have add a void surface that I pasted to the existing surface. Thought that was a solution until I tied an assembly to the pasted revision and it ripped my corridor and profiles beyond any recovery.
