How to populate a brep with "facade" pattern?

Hi guys,

iI hope your outstanding problem-solving skills would help me this time as well. I got a cube-like building which structure is a weird organic steel frame that eventually spread out of the cube becoming a bridge.

I managed to build a definition for the cube and the shape of the structure, by lofting two parts (inside cube struct and the bridge) and merging them together.

However I got problem on populating the surface with its frame. I know they should be surfaces rather than breps and that's why I tried getting surfaces out of it (brep components > face > 2 trimmed serfs) but got no luck so far.

Attached, along the definition, you can find some sketches and few test renderings I got by baking the final brep (2 surfaces) and populating them back again in gh separately. Got ugly results at their intersection though.

Any clue? I'm in your hands!

When you are mashing two breps together like this, you end up with a couple of trimmed surfaces...it's very difficult to get the seams along two such geometries to match up in a satisfactory way (so that you get that continuous, organic quality you are looking for).

I would suggest that you take a look at this approach outlined by Daniel Piker. It involves some "hand" drawing of simply polygons over your base geometry, but it should ultimately give you a satisfactory result.
