Beams: Array/Distribute/Stretch/Align

This thread on the Rhino for Windows Forum shows an operation which requires several steps to arrange a Beam-shaped Rhino solid into a complex array. Array/Distribute/Stretch/Align

A VaBeam performs exactly like the Rhino object. I was half-expecting a beam (like a VaColumn) to persist in a vertical orientation on one axis so that Orient alone (without the aid of the curve projected to the Cplane.) If it’s possible to invoke that constraint, please let me know. It would be a beneficial option, I think.
