My engineer has modelled a rather complex steel roof structure in Rhino. We have had a lot of succcess in exporting from Rhino to dwg or dxf, linking CAD and then placing a beam by picking a line in the linked 3d model.
However, some of the geometry has been modelled as a spline and curves in two planes. Revit does not recognise these splines (and it does seem to crash the software quite often). So we exported from Rhino as 2004 polylines in dxf. These come in and are pickable but Revit breaks down the polyline into individual arc lengths and so I have mutltiple beams when I only need one.
1. Does anyone know a better way of doing this
or
2. Is there a way of joining beams?
or
3. Can i force the polyline into thinking it is one long line and pick that?
Many Thanks
