The Display menu contains commands for controlling the data, which are displayed in the graphics and other windows.
Data Format allows you to choose which stability data are tabulated. A dialog box allows you to choose from a range of stability variables. See Setting the Data Format on page 138.
Allows you to customise how you wish to calculate the coefficients as well as the display format for the LCB and LCF.
See Customising Coefficients on page 32 for more information.
The units used may be specified using the Units command. In addition to the length and mass units classes, units for speed (used in wind heeling and heeling due to high-speed turn etc. criteria) and the angular units to be used for areas under GZ curves, may also be set. The angular units for measuring heel and trim angles are always degrees. See Setting Units on page 32 for more information.
This function may be used to synchronise the display in the Design View window with one of the sets of data in Results window. The view may be set from any of the results from Upright Hydrostatics, Large Angle Stability or Equilibrium analyses. Simply highlight the column or row that corresponds to the condition you wish to view and select “Select View From Data”; the Design View will change to match the condition in the selected row or column in the Results window.
The visibility of tanks, compartments, labels, hull contours, and other items in the design view may be set by using this dialog.
The grid submenu allows you to hide the grid or show the grid with or without station grid labels. The grid can only be displayed when the vessel is in upright position on its design waterline. The option to display the grid will be greyed out when the ship is currently displayed in, for example, a trimmed state at the end of an equilibrium analysis. Switching analysis type puts the boat back into upright position on its design waterline.
Selecting the Show Single Hull Section item from the Display menu will change the display in the Body Plan window to show only one section through the hull, as well as a control box, similar to the one in Maxsurf, in the top right corner of the window.
The section being displayed can be chosen by clicking on the section indicators at the top of the control box. Alternatively, the section chosen can be changed by pressing the left or right cursor keys on your keyboard. This allows you to rapidly step through the hull sections from bow to stern.

When the Perspective window is the current view for the model the Render option may be toggled on and off to render the surfaces.
When the Perspective window is the current view for the model the Render Transparent option may be toggled on and off. Render Transparent makes the hull surfaces of the model semi transparent so that the rendered tanks and compartments within the model may be viewed.
This command is available for any analysis that steps through several steps. For example, when a waveform has been specified and an equilibrium analysis is selected or after a Large Angle Stability analysis over a heeling range.
Selecting Animate will animate the stability sequence in the design View window, through the range of heel angles specified. You may set the initial viewing position in the Perspective View window using the Pitch, Roll and Yaw indicators. When Hydromax has finished calculating the frames the sequence may be replayed by moving the mouse from side to side. Clicking the mouse button will terminate the animation.
If animation is chosen after an Equilibrium Analysis has been performed in waves, the animation will automatically cycle through the full range of wave phases, giving a simple visual simulation of the motion of the hull through the wave.
Hold the shift key down while selecting the command to save the animation.
Access to the Frame of Reference is intended for information only. You are not expected to change the Frame of Reference in Hydromax.
If the position(s) of the Baseline and/or Perpendiculars need to be changed from those defined in the Maxsurf model, they may be changed using the Frame of Reference command. It is highly recommended that the correct frame of reference be set in Maxsurf prior to loading the design into Hydromax. This will ensure that a consistent frame of reference is used in all the programs. See: Setting the Frame of Reference on page 20.
Access to the Zero Point is intended for information only. You are not expected to change the Zero Point in Hydromax.
This function sets the longitudinal and vertical reference point for all measurements, including the centre of gravity. It is highly recommended that the correct zero point be set in Maxsurf prior to loading the design into Hydromax. This will ensure that a consistent zero point is used in all the programs.
