An ''edit mode'' for the existing topography
It would be nice to have an edit mode so we can select all the undesirable pts and then click ok to retriangulate. Now we have to do it pt by pt and it retriangulate on every single pt so it makes the process a lot longer.
I generally don't have to do this but I received some topos with some bugs in them so a bunch of points aren't valid.
Thanks for the feedback.
As you said on your next comment, you may choose to delete several points at the same time using 'Window Delete' or 'Polygon Delete'. Right click Existing Topography then select 'Window Delete' or 'Polygon Delete' to delete multiple points at the same time.
This option is also available for Proposed Topography to allow manual editing of the surface.
