To Add an Endpoint on a Second Curve or Edge
1. After you pick the spline, click 2nd Crv/Edge on the PNT LOCATION menu. The 2ND CRV/EDGE menu appears.
2. Click one of the following:
◦ Pick Point—Adds a spline endpoint at a selected point on a curve or edge.
◦ Nearest Pnt—Uses the point on a curve or edge nearest an end of the current spline as a reference.
◦ In Osc Plane—Uses the intersection of a curve or edge and the osculating plane at the spline end as a reference (the osculating plane is the plane defined by the curve’s normal and tangent vectors).
3. Pick a location for the point. The new spline highlights in green and the old spline highlights in red.
4. Click Confirm on the CONFIRMATION menu to accept the new spline shape.
5. Click Cancel to return to the SPLINEPNTS menu.
