The Overset tab contains all the options necessary to control the display of overset data while examining your grid. Note that this tab is only available when an overset assembler has been selected in the Grid, Overset, Attributes panel.
Note: The Overset tab is only visible in the Examine task when an overset assembler has been selected in the Grid, Overset, Attributes panel.
The Focus frame is only visible when multiple blocks are loaded into the Examine task.
You may use this frame to select a particular Focus block. When combined with Focus Display Style (explained below), this functionality will restrict the visibility of overset data (i.e. fringe, hole, and orphan points) to the objects associated with the selected Focus block.
Note: The Focus frame is only visible when multiple blocks are loaded into the Examine task.
This frame provides two methods for selecting the Focus block. First, you may iterate over over all blocks loaded in examine with the left and right green VCR button. Second, you may interactively select the Focus block. Use the Begin command to enter into pick mode for the Focus block. The command button label changes to End. Press End to leave pick mode. Cancel allows you to exit from pick mode without making any changes to the primary selection.
The Display Style frame contains several options allowing you to control overset element visibility:
|Off||Overset elements are hidden.|
|Cutting Plane||Overset visibility is restricted to those intersecting a cutting plane.|
|Focus||Overset visibility is restricted to the focus block. Refer to the Focus frame explanation above for more details on selecting the current focus block.|
|Global||Overset elements are displayed for all blocks loaded into examine.|
Tip: You can use the Ctrl+Shift+F6 shortcut to toggle on/off the display of pervasive overset data.
The Show Fringe/Donors frame contains several options allowing you to control overset element visibility specific to fringes and donors:
|Off||Fringes/Donors are not rendered.|
|Fringe Only||Fringes are rendered, but donors are not rendered.|
|Fringe Donors||Fringes and Fringe Donors are rendered.|
In the Show frame for Overset Tab, you can further customize overset element visibility:
|Hole Grid||Show cells removed by the hole cutter during overset grid assembly.|
|Hole Symbol||Show a hole symbol to represent cells removed by the hole cutter during overset grid assembly.|
|Orphan||Show orphan elements. Orphans are fringes which do not have a suitable donor.|
|Orphan Donor Candidates||Show orphan donor candidates.|
Caution: PEGASUS 5 and Suggar++ both present different ways of defining the overset grid system. Even though we have unified the overset interface, good familiarity with these assembly software packages is required.
While in the Examine task, you have a direct interrogation tool known as the probe. Simply move the mouse cursor over any rendered overset object (i.e. fringe, hole, orphan) in the Display window and the object currently under the mouse will be highlighted. Right-clicking on the object with the probe will open up a context menu with the command Show Overset Data (shown below). Clicking on this command will print out a detailed report to the Messages window containing meta-data associated to the overset object in question.
In the figure above, note that the XYZ coordinates of vertices and any reference to an entity or group of entities written to the Messages window are presented as hyperlinks. Clicking on a hyperlink representing an XYZ coordinate will render that point in the Display window as a yellow square. On the other hand, clicking on a hyperlink referencing an entity, will select the entity in the usual way. Additionally, right-clicking on a hyperlink will bring up a context menu with additional options based on whether it is a point or entity hyperlink. Please refer to the Selection Methods and Messages Window sections for further details.
