Rotate column

Am pretty new to Rhino Grasshopper. How can I rotate the series of the column radially along a circle?

Create a vector from the origin (center) to one of the endpoints on each line, then orient the columns using the “up” vector for the column as the initial orientation and the new vector as the final orientation.

Thank you for the reply. can you pls explain graphically? am totally a newbie in grasshopper.

The best way to get a useful reply is to post your Grasshopper file. It isn’t clear to me from your description what you want to do?

Actually, just use polar array
