Applying geometric transformations to selected control points

The Transform item under Tools in the selection list of the Curve through Control Points command enables you to apply a transformation — a translation, a rotation or a rototranslation — to the currently selected points.

Note
The Transform option — as well as the Step and Scale ones — are not available unless there are valid control points selected. For this reason, when the selection is reset the said options are closed.
Please also note that the mentioned options are mutually exclusive: any time you select a new option, the current modification will be completed and the new one will begin.
Finally, note that both with the Scale and with the Transform option, the default location of the start point is the center of mass of the currently selected control points.

The curve shape will be updated dynamically while the transformation is being applied.

After selecting one or more control points, click on Transform under Tools in the selection list. A spherical set of handles will be displayed.



To define a translation, once all the control points have been selected, you can simply click on the origin and then specify the end point of the translation.
Before applying the transformation, you can also redefine both the position and the orientation of the handle system.

See the description and the step-by-step examples of the Move Copy Entities command for further details (the methods to be used to apply geometric transformations to control points are exactly the same).
