How can I smoothly "blend" between 2 STLs? I have 2 STL files, and I'd like to join them (not only as &quot;join them into a single object&quot;, but &quot;physically&quot; join them). I'm using blender 2.8.
I'll give an illustration right away to clear what I'm talking about:

The STL in the center is purely flat, while the STL around it is more complex.
Is there any way that I can make these 2 STLs &quot;meet&quot; more or less smoothly so that the gap is filled and I obtain a single STL? Please consider that there might be lots of vertices on both STLs, so manually moving the vertices one by one wouldn't be a viable solution for me ;)
I'm a total blender noob, so maybe I'm simply not looking at the right software?
Thanks a lot!

You should be able to merge them with Booleans, be that the BoolTools addon or modifier. Take a look!
