Object editor
......
We have combined the best features of the curve editor and
curve stretch tools, and offer them in an object editor that now
works on surfaces as well.
In addition, you can now specify position and tangent
constraints at required locations on any geometry you want to
edit, and modify the shape of the curve or surface while
respecting these constraints.
The tool also provides construction history, enabling you to
edit the constraints you have previously created on a curve,
surface or curve-on-surface.
Choose Object Edit > Object editor and click a curve or surface.
