Copy Points

Hello,

I would really appreciate some help, I'm stuck with some features and kind of lost at the moment.

I would like to copy a point, in order to trim a solid geometry. I need to rotate it four times (90°) to have something which is symmetric. I managed to create one point, I can rotate it without any problem. But how can I copy this point?

My geometry is attached to get an idea how it looks like.

Thank you!

David
