It's been a little while since the last update, but I have been working on some subtle and not so subtle improvements.
The primary new feature is the ability to generate and import to Revit beams with curvature (arc and splines). This includes preservation of cardinal points. For the time being it works with IFC4, I will enable IFC2x3 initially with mid cardinal point. At present the axis curve must be planar, but if you need non-planar I'll take a look at it.
If you look carefully at the image (or try for yourself the models), then you'll see Revit alters the end details at the junction. These elements using the IfcSurfaceCurveSweptAreaSolid shape representation, which is totally under utilized in my opinion. I've seen some client models where IFC is not practical to use due to bloated file size from faceted brep shape representations of these parts.
Here's the Grasshopper file, and here's the IFC file.
