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

Define the axis by clicking two points on a View window. Distance to the axis is calculated for each point to get a deformation parameter. The control curve is then evaluated by the deformation parameter to get the amount of deformation. 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 Rotate2D tool has the following options:
