.This will create a pleasing curve for our deck camber.Make a copy of this arc to be used later for the deck.Draw the camber arc and copy up.Step-by-Step: Draw the camber arcDraw the arc1 Make the cCamber layer current.2 Start the Arc3Pt command.3 At the Start of arc prompt, use the End object snap to pick at the lowerendpoint of the vertical line on the port side.4 At the End of arc prompt, use the End object snap to pick at the lower endpointof the vertical line on the starboard side.151Rhino Marine: Offshore Racing Power Boat5 At the Point on arc prompt, use the Mid object snap to pick at the midpoint ofthe horizontal line.Draw the camber arc from the vertical line lower endpoints and the moved linemidpoint.Make a copy of the camber curve1 Select the arc.2 Start the Copy command.3 At the Point to copy from & prompt, in the Right viewport, pick a point.4 At the Point to copy to prompt, use Ortho to pick a point directly above thepoint selected for the origin.Copy the camber arc up.Copy the camber arc into positionTo place the camber curve accurately on the sheer at the transom, in Right viewport,draw a vertical line from each corner of the transom up to a point above the newlycreated camber curve.152Rhino Marine: Offshore Racing Power BoatCopy the camber curve.(Save one untrimmed camber curve to use at other stationslater) Trim the copy to the two vertical lines and move the result to the corner of thetransom.Copy the camber curve to the corner of the transom.Step-by-Step: Copy the camber arc into positionConstruct lines from the transom corners1 Start the Line command.2 At the Start of line & prompt, pick the starboard transom corner on the hullsurface.3 At the End of line & prompt, in the Right viewport, pick a point above thecopied arc.Draw a vertical line from the starboard transom corner.4 Select the vertical line.5 Start the Mirror command.6 At the Start of mirror plane & prompt, type 0.153Rhino Marine: Offshore Racing Power Boat7 At the End of mirror plane & prompt, in the Right viewport use Ortho to dragthe mirror plane line up along the z-axis.Mirror the vertical line to the port transom corner.Trim the copy of the camber curve to the width of the transom at sheer1 Select the two vertical lines from the transom corners.2 Start the Trim command.3 At the Select object to trim & prompt, in the Right viewport, pick the copy ofthe camber curve arc outboard of the transom corners on each side.You should now have an arc whose chord length will fit the width of the slopedtransom at the sheer.Trim the copy of the camber arc to the vertical lines.Move the trimmed camber curve into place at the transom1 Select the copy of the trimmed camber curve.2 Start the Move command.3 At the Point to move from & prompt, use the End object snap to pick thestarboard endpoint of the trimmed camber curve.154Rhino Marine: Offshore Racing Power Boat4 At the Point to move to prompt, use the End object snap to pick the end of thestarboard transom corner.You should now have a curve that ends at the intersection of sheer and transomon each side.Trim the transomTrim the transom with the hull sides and the camber curve.You should now have a transom panel that matches the hull around its outer edgesand matches the camber curve across the top.The trimmed transom.Step-by-Step: Trim the transomTrim the transom top1 Set the sHull layer current.2 Be sure all surfaces are on layer sHull.3 Select the transom camber curve and the hull on both sides.4 Start the Trim command.155Rhino Marine: Offshore Racing Power Boat5 At the Select object to trim & prompt, select the transom outboard of thehull.You should now have a transom panel that matches the hull around its outeredges and matches the camber curve across the top.The trimmed transom.Erase all the construction curves1 Delete the construction lines created in this phase of the project except theoriginal untrimmed camber arc.Save the untrimmed camber arc.2 Save your work.Join the transom to the hullJoin the transom to the hull and check for unjoined edges.Unjoined edges after joining the transom to the hull.156Rhino Marine: Offshore Racing Power BoatStep-by-Step: To finish the hull and transomJoin the hull surfaces1 Make layer sHull current and turn off all other layers.2 Select all the surfaces.3 Use the Join command to create a single polysurface.4 Select the polysurface and use the ShowNakedEdges command to check forunjoined surfaces.Unjoined edges after joining the transom to the hull.5 Save your work.Create the deckTo complete the hull, you need to create a deck.This is where the spare camber curvecomes in.Create construction linesAt five (or more) locations along the sheer, create a vertical line.Draw one line andcopy it however many times you need (there are four copies in the example) usingEnd and Near object snaps.Mirror the vertical posts across centerline [ Pobierz całość w formacie PDF ]
