Page 8 Modeling a Sailboat: Backbone

On this page, the hull edges and deck will provide the curves needed to finish the "backbone."

Duplicate the edges Dupedge (Curve/From Objects/Duplicate Edge) of the hull, as shown below.

From the front view, project the dupedge curves to the construct plane ProjCp (Transform/Project to CPlane). This will put all the curves needed on the construction plane.

The following steps will show how to trim the curves:

Select and Hide the hull using Edit/Visibility/Hide.

Hit Trim, select the deck curve as the cutting object, and trim off the pieces indicated by the arrows below.
