The following new operations have been provided for objects in existing license categories.

• add_polyline

• insert_polyline
• order_polygroup
• plane_from_body_facet
• solid_from_3_polys
• surface_from_2_bcurves
• sweep_sheet_wire

• In earlier versions of the software, paste would paste a copy of the last pasted object, not necessarily the original copied object. This was inconsistent with other Microsoft products. Accordingly, paste now pastes the original copy.
• It is now possible to rearrange the order of sub-bodies within a solid_body, and also generated panels.
• Series objects can now be copied from the constrained outputs of other objects and pasted into your own custom made graphs.
• User-created graphs now export correctly as KCL.
• Layers have been enhanced - the user now has 256 definable layers as well as the system default layers.

The behaviour of the following objects has been improved. Changes in the structure of objects are automatically incorporated when opening design files saved in previous versions of Paramarine:

• bcurve - graphical appearance has been improved
• building_block - now correctly places its constituent 'node_positions' and 'weights' following a rotate_datum operation about the Y axis.
• char_space - can now be used to define space supply (either deck area or volume) from a parent building_block's 'solid' geometry as an alternative to the 'location'. This enables Design Building Block models to be developed in isolation from the vessel's solid_body subdivision in the first instance.
• char_tankage, char_tankage_compensated - can now be used to define the tank's 'shape' from a parent building_block's 'solid' geometry as an alternative to the 'location'. This enables Design Building Block models to be developed in isolation from the vessel's solid_body subdivision in the first instance.
• command - selections that relate to single shaft and rudder settings have been made more explicit. Improved validation ensures that commands for single shaft / rudder cannot be used if the ship has twin shaft or rudder as appropriate, and vice-versa.
• eff_power_fouling - the calculation of appendage effective power due to fouling has been corrected for the following appendage types: powering_app_rudder, powering_app_shaft_bracket_arm, powering_app_stabiliser_fin. Corrections will take place automatically when first viewed in V3.1.
• equipment_instance - now correctly places its constituent 'node_positions' and 'weights' following a rotate_datum operation about the Y axis.
• grounding_analysis - now has its own 'damage_case' pointer so that the impact of varying the damaged state of the vessel on the grounding scenario can be assessed.
• powering_data_from_geom - this object which derives parameters useful in powering calculations is now available through the solid_modeller license configuration.
• propeller_finder - now contains the thrust correlation factor 'Tr_on_Tm' so that the user can define the characteristics of a model propeller and the software will automatically deduce the corresponding full scale performance.
• surface - graphical representation has been significantly improved so that, for example, slope discontinuities (knuckles) are now shaded correctly. Objects that work with the facetted form of the surface (e.g. geometry_chopper) will not be recalculated immediately in V3.1, but will update with new results when they next recalculate naturally.
• tri_command_mainhull, tri_command_sidehull - selections that relate to single propulsor and steering device settings have been made more explicit. Improved validation ensures that commands for single propulsor and steering device cannot be used if the ship has twin propulsors / steering devices as appropriate, and vice-versa.
• watertight_damage - improvements to the internal wiring of the object.

• 3d_from_2d - minor improvement to functionality.
• set_bcurve, set_surface - these operations now cope with bspline entities up to order 10.
• thicken_sheet - only positive values for thicknesses are now allowed, in order to avoid confusion.

2D and 3D polyline entities can now be read from DXF files.

There are numerous improvements to the Graphical User Interface. The most significant of these are:

• Generic Tabular Dialogs - The Copy to Clipboard function that gives an HTML clipboard format is now optional but defaulted to ON.  This has been done because MS Office versions before Office 2000 are not able to recognise this format.  To turn it off change the option at Tools > Customise > Tables.  Scrolling of long tables is now smoother.  If a large table is requested the user now also has the option of cancelling it as well as restricting the number of lines displayed.
• Graphs - These have been completely revised to increase performance and features.  New features include picking of series and axes, these being highlighted on selection, tool tips to indicate data values, and the ability to display curves of two different Y axis types against a common X axis in Cartesian graphs as well as reversing the displayed axes.  New context menus are available allowing the data markers, lines style, font type and size and axes properties to be changed on a per-graph basis.  It is also possible to zoom in on specific areas or a graph and subsequently pan around.  Keyboard accelerators have now been enabled in this view.
• Users may choose advanced customisation to have lines displayed in the graphics pane and on graphs with anti-aliasing to improve their visible smoothness.
• Double clicking in the treepane on specific objects results in specialised input methods rather than default table views.  These are: pointers, variables, density objects, time objects, FSURF input filename and visualNastran file.  This is in addition to displaying graphs, pictures, etc.
• Tag windows can now have carriage returns typed as normal to create long text information.  The dialog also no longer takes focus regardless after an update of all views.
• Colour layer properties dialog enhanced to remember changes without pressing OK if the selection changed.  It is now possible to add up to 255 user defined layers.
• Open to level in the treepane is only available if an item has children.
• Object properties can now be displayed using the Alt-Return standard hot key configuration.
• Text can now be edited correctly in the Properties...Sequence dialog.
• Numerous updates to reports.
• Added custom colours to the standard colour dialog are now retained.
