Prior to sketching the two-dimensional curves, it is useful to draw bounding boxes soyou can adjust the two-dimensional curves to meet the design parameters.Accordingly, on the Bounding Boxes layer, in the Top viewport, draw a 68-foot by 8-foot box on the base plane for the plan view of the sheer.Top view bounding box.Draw a 68-foot by 8-foot box in the Front viewport on the center plane for the sheerin profile.Use the InterpCrv command to sketch the rabbet line profile on the center plane.Since you will have a two-inch deadflat from stem to stern, immediately move thisprofile one inch off centerline. Attending to this sort of detail early in the designprevents having to go back later and make modifications to an otherwise finishedmodel.
