Is there a way to add a feature to a terrain model without the whole model retriangulating? ORD CE 2021 R1

Question

I am aware that I can add a border to stop the edge tringles from getting rebuilt, but after adding any feature, the whole terrain model rebuilds and drops all interior edits that have been made (eg, flipping triangles). This makes it difficult when receiving field data on a day-by-day basis.

Clayton, this subject has come up before on this forum, and there is no way to stop the surface from reprocessing the triangles. That's why some of us will either do any 'flipping' as part of the final surface clean-up. But that's not a solution to additional survey being added a month later. Additionally, some of us basically avoid the flip face tool all together. InRoads never had such a tool so us 'InRoads users" became very accustom to just adding a breakline to force the triangle leg to form the way we want.
