Sculpting rotational symetarry

I am modelling a circulkar marquee roof and I have sculpted the folds in one section of the roof in dynamic topology.

How can I quickly copy the geometry around. Is there a rotational symetize option or should I just duplicate the section and manually join them.

Cut the object in half then use the mirror modifier,i’m not sure if there is a symmetry option for default sculpting though.

Edit:make sure to make a backup of the object first.

Double edit: Discard my comment,misunderstood what you meant.

You could have used the Radial Symmetry option when you were sculpting the one section.

Here it is so far. How cqan I copy that segment round the others?
