List of overlapping/intersecting features for "replace terrain points"

[BertholdReiter]

Hi all,

I hate to bother you, but after several days of fruitless efforts to find a solution I thought I'd just ask if anyone knows if what I want to do is possible.

So I have this Terrain-Dataset containing around 500 Multipoint feature-classes. Every other month or so I'm going to get updates for some areas that randomly overlap some feature-classes. My plan was to use "replace Terrain points" to update the terrain. This tool needs as input:
-the feature-class in which points need to be replaced
-the feature-class with which to replace them
-(optionally) a clipping polygon

What I wanted to do was:
-check which Multipoint feature-classes in the Terrain need to have a part of their points replaced
-output these as a list of feature-classes
-iterate over this list in the model-builder to run "replace Terrain points" for all new feature-classes

My efforts were already foiled by the first step. So my questions at the moment are:

Is there a way to determine which feature-classes have common areas and output a list of filenames/feature-class names to use as a basis for further processing?
Is there an obvious easier way I fail to see?

My current approach (which I hope will get the work done but is unsatisfying on an intellectual level) is to create a single feature-class containing all the points of the original terrain, create a new terrain and then run the replace tool for that new terrain.

Thanks for reading and (in advance) for responding!

Yours,
B. Reiter

Ok,

nobody seems to have any better ideas. Or maybe this was just the wrong subforum for the question.

Anyway, I'm still in the process of implementing my "workaround", which seems to be viable but kind of defeats the purpose of Terrain-datasets as far as my understanding goes.
If I eventually come up with a better solution I'll post it here, until then thanks for taking an interest.

Best regards,
