REPS

The buttons B-spline, Bézier and Linear next to the text REPS determine the input representation of curves produced with the CURVE menu commands.

For example, if the type is set to B-spline, the command CURVEÞDesign:Input assumes that the points entered are control points for a B-spline curve.

The default value for the input type is B-spline, which generally applies well to any kind of modeling work.
