create 3D beam system

[Ning Zhou]

i'm trying to create beam system directly from face based roof using Revit API, get 3D profiles from roof, make beam system, etc., so far it works for planar roof faces, Revit API do provide an option for 3D case, but it doesn't work for me if i set is3D to true:

BeamSystem bs = rev.ActiveDocument.Create.NewBeamSystem(profile, sketchplane, direction, true);

from Revit SDK, it says "If the BeamSystem is 3D, the inputted sketchPlane must be a level, or an exception will be thrown out", so i used Level instead of SketchPlane but it won't even compile, any inside knowledge will be very much appreciated!

does anyone sucessfully create non_planar 3D beam system using Revit API?

Hi. To create a 3D Beam System you must set doc.activeview.sketchplane = sketchplane of the 3d beam system, then BeamSystem sistviga = doc.Create.NewBeamSystem(arraycurve, doc.ActiveView .SketchPlane, XYZ.BasisY, false); If you set it to true it doesnt work, why? i dont know.
