Select components, RMB, "Rotate Group 90", LMB on desired place.
Thanks for your reply
PADS does not have an explicit command that allows you to rotate a group of components using an arbitrary angle.
Such command exists for 90 degree increments. What you can do is to select a group of components, RMB > Create Union,
Properties, set new rotation value, OK. RMB > Move to reposition the group (if needed), RMB > Break (the union).
Union Properties dialog shows the rotation of the union "base" component. When you create a union the last selected component
becomes the "base" component.
