Rotate

Description

The selected part of a structure can be rotated by dragging it while in rotation mode. Rotation mode can be turned on and off from the "Mode" menu (usually key-shortcut r) or with the rotate button. The center of rotation is indicated by a target, which can be repositioned with the mouse.

The current helix (the one which has the current item) can also be oriented in a given direction using the "Geometry toolbar" or "Orient" options in the "Geometry" menu. The selection will be rotated together with the current helix.
