OpenSTAAD Break Beam

Hell...

I have made Excel based VB program using OpenSTAAD. I am unable to create geometry using this program. However I am unable to break beam (at intersection)  using OpenSTAAD command. I have to manually select Nodes & then use Break Beam command.

OpenSTAAD have command for Selection of Nodes i.e. objOpenSTAAD.Geometry.SelectMultipleNodes NodeNos

but i have not found any command to break beam.

Please help me how to do this through Excel VB program.

Thanks in Advance
