Right click on grouped geometry and pick FFD > n xn (where n is the number of control points)

That will create a group containing the control points. Double a point to start freeforming.

Which version if FFD do you have? TIG released an update with fixes this week.

I installed this >>> SketchyFFDv2

I moved the control points but my object not updated.

I right click into my object but cannot see "Update FFD"
