Normally, you do not need to perform any operations described in this section. However, in certain computer configurations, considering CPU speed, memory size, your model size, the number of simultaneously opened documents and the number of other applications running at the same time, you may wish to find tune some of the optional parameters. These parameters can be displayed and modified from Options dialog accessed via the Tools>Options... pull-down menu selection. Once you have the Options dialog displayed, you can find three groups of parameters as following.
Maximum number of tabs in the Right Pane (default 10): The right pane displays the most recently accessed Canvas Views and Grid Views. If you have a limited physical memory, large Project Models, or many simultaneously running applications, you can reduce the value of this parameter. Increase the value if you would like to see more in the history.
Maximum number of rows in Message Views (default 1000): Depending on the messages generated by your simulator, you may need to adjust this parameter. If the number of messages exceeds this limit, all the older messages will be truncated.
Maximum number of rows in Result Views (default 1000): Depending on the requirements of your simulation results, you may need to adjust this parameter. If the number of results exceeds this limit, all the older results will be truncated.
Maximum levels in the Undo/Redo Buffers (default 20): This is essential for Canvas View editing purposes. Because all these buffers are in memory, you may need to adjust the number of levels in order to fit your operations better. For example, if you have a few large group editing operations, you may want to set the levels lower to occupy less memory. Doing so, however, may cause loss of information when you need to recover an earlier state beyond the number of steps.
Number of objects kept in the Object Toolbox (default 20): This parameter determines the size of the Latest Selections in the Object Toolbox. Increase or reduce the size as needed.
Array size limit before displaying warnings (default 10000): This parameter is only for invoking a warning message whenever the user allocate a data array larger than this value. It is not a hard limit for determining the largest array size. If you are aware of the size limit and do not wish to see the warning message, simply set the value to 0.
User zoom factor (in percent) for Canvas Views (default 100): The current user zoom factor for Canvas Views can be set here or from the User Zoom button in the View Toolbar.
Default Bottom Pane height in pixels (default 100): When SansGUI needs to display the bottom pane for certain operations but it has been reduced to 0 in height (hidden), this parameter will be used.
By default, SansGUI detects the 3D graphics configurations of your computer to decide how to display Graphics objects in Graphics Windows. Under certain circumstances, however, you may need to select a different option manually: 1) you have a special graphics controller card that supports OpenGL with accelerated hardware but SansGUI cannot detect it, and 2) you are encountering a Microsoft generic OpenGL implementation bug, Microsoft Knowledge Base 272222, with which the Graphics Windows are not completely rendered along their right and bottom edges. The options are:
Let SansGUI detect graphics configurations automatically: SansGUI checks your computer and makes the best judgment on how to render 3D graphics.
Render graphics to windows or accelerated hardware: Select this option if you have a special graphics controller card with its own device driver and/or accelerated 3D graphics hardware.
Render graphics to bitmaps before displaying in windows: Select this option if you find the graphics display is incomplete, with black bands at the right and bottom window borders when the window is enlarged.
The change of this option is effective only in Graphics Windows opened subsequently. You need to close all previously opened Graphics Windows and reopen them to be effective.
