Rotate with deformation as a function of projection to an axis.

Define the axis by clicking two points on a View window. Each point is projected to the axis to get a deformation parameter. Points that project to near the first end of the axis get smaller deformation parameters than points that project near the second end. The control curve is then evaluated by the deformation parameter to get the amount of deformation. click on a View Window to define the center of rotation. Click on a View Window to define the point you want to rotate about the rotation center. Move the mouse until desired rotation is achieved and click to accept the tool.

The Rotate1D tool has the following options:
