First curve / Second curve

The "curve" field allows us to select the two curves to limit and give the machining direction of the sweeping.

- The orientation of the two curves (1) and (2) are represented by two yellow arrows. Those arrows must have the same direction.

To reverse the direction of the curve double-click the arrow on the curve.

- The arrow (3) allows to invert the machining direction.

The curves can be opened or closed.With two closed curves the origins must be correctly positioned to obtain a good synchronisation between the two curves.
