What do you do if a survey crew takes a lot of isolated patches of topo areas. Think, maybe, for quadrants of urban intersection corners - with no shots (and no intent) to connect these "terrain islands".
Out of the box (fieldbook) it will want to create a single terrain from all the points. Max triangle length can help trim out bad triangles, but still remnants of nastiness.
Another example is widened exteriors in corridors.
Is there an easy/automated way to get individual terrains for each island which can then be added and managed in a Complex Terrain? Complex Terrains work nicely with a base terrain that surrounds all the islands...
Graphic filter with fences/selection sets for semi-automated creating of individual terrains is a semi-automatic solution. Is there better?
Asking for a group of friends...

Jeff,
I agree with Mary. Best practice would be to isolate the raw imported data and bring each area of data into separate fieldbooks. If thats a hastle you can create a selection set of a single area of topo data and then do the following:
- hold the shift key on your keyboard and do not let go. If the shift key doesn’t work it might be the ctrl key.
- right click on “Fieldbook”….not the actual project fieldbook, but the one labeled fieldbook directy above the project fieldbook
- select create terrain model from selection set
- once the terrain is created then you can let go of the shift or ctl key!
Hope this helps!
looks like that is the consensus. thanks, Chris!
