There is also, on the line data form, a choice of which pen to use to draw the segments. Separate pens are used for the segments and nodes, so you can, for example, increase the pen width used for the nodes to make them more visible.

Lines are drawn as a series of straight lines, one for each segment, joining points drawn at each node.6D buoy wings are drawn as rectangles in either the 6D buoy pen or the wing type pen as determined by the wing type data.Lumped buoys have no defined geometry, so the vertices and edges or panels are explicitly user-defined on the buoy data form. Spar buoys and towed fish are represented by a stack of cylinders and are drawn accordingly, with a choice of square or circular cylinders. 6D buoys are drawn as a wire frame of edges and vertices.3D buoys are drawn as a single vertical line of length equal to the height of the buoy.Vessels are drawn as a wire frame of edges and vertices defined on the vessel and vessel types data forms.As well as controlling the pen colour, width and style, you can also control the number of lines used to draw a shape. Shapes are drawn either as wire frames ( blocks, cylinders and curved plates) or as a grid ( planes).This line or grid is drawn using the sea surface pen. If the type is set to grid then a grid of lines is drawn, aligned with the primary wave direction.

If the type is set to single line then one line is drawn, aligned in the primary wave direction (that of the first wave train). This is controlled by the user's choice of surface type specified on the drawing page on the environment data form. The sea surface is drawn as a grid or as a single line.The seabed is drawn as a grid using the seabed pen.You can control both what is drawn and the drawing data used. The wave, current and wind directions can be drawn as arrows in the top right-hand corner of 3D views. The various coordinate systems can be drawn as small triplets of lines showing their origin and the orientation of their axes.In a wire frame view, the various specific objects are drawn as follows. To suppress drawing either set the line style to null (the blank style at the bottom of the drop down list) or else hide the object. In Windows, a line width of zero does not mean "do not draw" – it means draw with the minimum line width. To change the pen colour, click the colour button on the data form and select the new colour. for an object at any time by editing the drawing data for that object. The numerical model and research results in this paper can provide some guidance for the research and construction of the cable laying of booster stations for marine renewable energy power plants in real sea conditions.Objects are drawn as a series of connected lines – a wire frame – with the pen colour, line width and style (solid, dashed etc.) defined by the object's drawing data. And the variation of effective tension at both cable ends can reach 1.67 times that of cable ends under usual random waves. When extreme waves appear, pitch, heave and heave acceleration of the laying ship and tension of the cable ends increases obviously. The current also has some influences on the submarine cable laying, and the maximum effective tension of cable produced by the combined wave-current action is 1.35 times that of cable with the wave action alone. Research results show that the tension and curvature of the cable are large under the condition for wave direction perpendicular to the ship axial direction, which is a relatively bad sea condition. usual waves, waves with current combined and possible extreme waves. The motion response of laying ship and the hydrodynamic characteristics of submarine cables are simulated here under three sea conditions, i.e.
