Just in the process of trying out the "site model" tool for the first time.
If I understand correctly, embedded within a "site model" object is the information about the "existing" landscape, plus modifications to that, creating the "proposed" landscape.
And I can control which set of information is displayed - existing or proposed - in the object's OIP.
But doesn't that mean that I then can't have each set of information displayed simultaneously within the sa
The big advantage of keeping one DTM is I guess that if at some point in the future I get better survey data (which is what I'd expect on my current project, so far only at outline stage with some of the site measurements being guestimated) then I simply replace the old "existing" data with the new but without losing the information in all the modifiers that convert it to "proposed".
In theory, anyway. I've not used the Site Model tool enough yet to have a feel for how reliable it is
