You can rotate elements using the Rotation command. You can duplicate element or move them using this functionality.
In this scenario, the geometry is moved keeping internal and external constraints.
Rotating elements also means re-computing distance values into angle values, if needed. However, note that, only non-fixed elements are updated.
The check box is selected by default, which means that the 2D elements you select are copied.
However, after you execute this command, your preferences are stored and saved for the next usage.
Following check boxes are available under Keep constraints:
You can also specify coordinates in the boxes in the Tools Palette, or specify a value for the rotation angle in the Rotate dialog box.
