That would be news to me - I definitely put in a lot of effort so that snaps are snapping when they say they are snapping...

Can you please post your updated .3dm model file?

It looks like that is still an unjoined edge problem. If your surfaces have too much of a gap between them right in that area, it is possible for those edges to not get fused together, but still have it all select as one piece because all the other edges did get joined.

Basically like this:



The above can be all joined so that it selects as one piece, but there is still a hole inside, the 2 edges across the hole from each other will not get joined if they are too far apart. Maybe in your case there are different elevations right along that edge?

I don't quite follow what the 2nd problem is on the iges import?
