Spline controled stroke.
A spline controled stroke, similar to zbrush curves or Sweep nurbs on C4D.
The idea is to create the control points of the spline and fill with voxels usind a round, square or stamped brush as a profile.
Similar to the line tool in the Medium Clay Brush, but instead of using a simple line to lock and guide your stroke, you can use a interpolated spline for more complex shapes and smooth curves if it needed.
