162 Firstly we will approximately size the simple yacht surfaces and then move it to an appropriate location. Select Surfaces | Size surfacesSelect the simple yacht surface and size to length 10m, Beam 3.5m & Depth 1.5m. Now move the simple yacht surface so the transom of the surface lines up with the Markers for the transom.A quick way to do this is by turning on the snap settings (F5), selecting all the surface control points then moving the control point at the base of the transom and then drag it to the marker at the base of the transom. Lower transom control point align with lower transom marker in Perspective View The simple yacht surface control point net contains 3 rows and 4 columns of control points. We will need to add more rows and columns to the surface control point net to get the required shape. Go to the profile view and add 3 more columns; one aft, one in the middle and one near the bow. Space the columns evenly along the length of the hull. Add extra columns in Profile View Now Go to the body plan view and add 2 Rows; one along the bottom and one up the side of the control point grid Your model should now look something like this: 164 Control points at the bow Once the surface corner control points have been moved to the correct location we can now fit the surface edges to the Marker data using the Fit edge to markers` command. Starting at the bow: Select the Markers that make up the bow stem, (hold down the shift key to select multiple objects) Select the surface edge to be fitted to the markers Select Markers | Fit edge to markers Fit bow edge to Markers 6HOHFW
