User Interface, Menus Printer Setup 46 w Calls up the Printer Setup dialogue window. This standard Windows dialogue is used to select which printer to use, and allows you to control the way that it is used – the details vary from printer to printer, and depend on the printer manufacturer's device driver currently installed. Please refer to the manuals for your printer as well as the Microsoft documentation. Print Display the Print form, allowing you to print 3D Views, Graphs, Spreadsheets or Text Windows. See Printing. Most Recent Files List of the most recently used files. Selecting an item on the list causes the file to be opened. Exit Close <strong>OrcaFlex</strong>. 3.5.2 Edit Menu Undo Drag Undo the most recent drag. This is useful if you accidentally drag an object. Cut Copies the current selection to the clipboard and then deletes it. Copy If there is a currently selected object (see Selecting Objects), then that object is copied to the clipboard. You can then use Edit | Paste to create duplicate copies of the object. The data for the object is copied to the clipboard in text form, from where it can be pasted into a word processor document. Note: After pasting into a word processor, you will probably need to put the text into a fixed space font since much of the data is in tables. If there is no currently selected object then the currently selected 3D view, text window, graph or spreadsheet is copied to the clipboard. Paste Insert object from clipboard. This can be used to duplicate an object several times within the model. After selecting Paste, the object is inserted at the next mouse CLICK position in a 3D view. If the current window is a Spreadsheet then the contents of the clipboard are pasted into the spreadsheet. Delete If the active window is a 3D View then the currently selected object is deleted. Before the object is deleted, any connected objects are disconnected, and any graphs associated with the object are closed. If the active window is a Spreadsheet then the selected cells are cleared. Select All Selects all the cells in a Spreadsheet. 3.5.3 Model Menu Model Browser Toggles the visibility of the Model Browser.
w New Vessel New Line New 6D Buoy New 3D Buoy New Winch New Link New Shape 47 User Interface, Menus Create new objects. The mouse cursor changes to the New Object symbol . The object is placed at the position of the next mouse CLICK within a 3D View. A three dimensional position is generated by finding the point where the mouse CLICK position falls on a plane normal to the view direction and passing through the View Centre. Vessels are always placed initially at the sea surface. Show Connections Report Displays a spreadsheet containing information about all object connections in the model. Delete Unused Types Deletes any types (e.g. Line Types, Clump Types etc.) that are not in use. This is sometimes useful to simplify a data file, or to find out which types are in use. Delete Unused Variable Data Sources Deletes any variable data sources that are not in use. This is sometimes useful to simplify a data file, or to find out which variable data sources are in use. Use Calculated Positions This menu item is available after a successful static iteration or when the simulation is finished or paused. If the model is in the statics complete state then clicking the menu item sets the initial positions of buoys, vessels and free line ends to be the calculated static positions. This can be desirable when setting up a model, since the positions found are likely to be good estimates for the next statics calculation. If the model is in the simulation paused or stopped state, then clicking the menu item sets the initial positions of buoys and free line ends to be the latest positions in the simulation. This is useful when <strong>OrcaFlex</strong> statics fails to find an equilibrium configuration. In such cases you can use dynamics with no wave motion to find the static equilibrium position and then click Use Calculated Positions. If a replay is active then clicking the menu item sets the initial positions of buoys and free line ends to be the positions at the latest replay time. Use Specified Starting Shape for Lines This menu item is an extension of Use Calculated Positions. As well as setting the initial positions of buoys, vessels and free line ends it modifies data for all Lines in the following way: 1. The Step 1 Statics Method is set to User Specified. 2. The User Specified Starting Shape data are set to the calculated node positions. As described above these positions are either the results of a static calculation or the results of a dynamic simulation. Use Static Line End Orientations This menu item is only available after a successful static analysis. Clicking the menu item sets the line end orientation data, for all line ends in the model that have zero connection stiffness, to the orientations found in the static analysis. This is done as follows. � For any line end with zero bend connection stiffness, the end azimuth and end declination will be set to the azimuth and declination of the end node, as found by the static analysis.
