How to fill a triangulated DWG?

I have a 3D polygon SHP file that I want to save as a hatched/filled DWG. To get a 3D CAD surface, I have to triangulate the SHP first or else I get flat polygons floating at their minimum height - this works, resulting in a surface consisting of line triangles.

Now I want to fill the triangles, but I can't figure out how. The DWGStyler can't do it. AreaBuilder seems to create some areas but leaves holes as well (and removes the SHP attributes!). GeometryCoercer (fme_polygon) doesn't work. So how is it done?

Screenshots:

1 - triangulated polygons, triangles are all grouped by initial polygon as can be seen by the selection

2 - selection zoomed in and deselected

3 - same, after AreaBuilder
