Any particular reason this file doesn't recreate intelligent walls upon import?

This file, recreates intelligent walls upon import.

I didn't debug it, but I would say it has to do with the wall footprint. Basically, in Revit, a wall is an axis that is vertically extruded, and has complicated logic for determining wall joins to other walls. It can be quite tricky via the API (internal or external) to reverse engineer the correct wall join information corresponding to a wall footprint that represents the post-clip information. I believe that if there is an IfcRelConnectsPathElements, it tries harder.

by footprint you mean the Curve2D on the GRAPH_VIEW context?
