Global-commands

Global commands may be executed from the any menu except from other sub-menus of the GLOBAL-COMMANDS sub-menu (i.e. no recursion). They allow the user to list information, plot only selected graphic entities, label lines, points, nodes, etc.

This documentation is taken directly from the Moviestar help files and included here in a hyper-text format for your convenience.

________________________________________

Clear

Clear the terminal screen. This command is most helpful when AUTO-ERASE is off, and you need a clean screen.

________________________________________

Color

Set color for the various entities and options listed in the sub-menu. Color is specified in terms of red, green, and blue color components. The value of each component may range from 0.0 to 1.0 or from none to full intensity respectively.

Background: Set the background color.
Constraint: Set the constraint color.
Coordinate-frame: Set the coordinate frame color.
Element: Set the element color. You will be asked to specify the element type (i.e. AXIQUADRILATERAL, AXITRIANGLE, BEAM, etc.).
Group: Set the group color. You will be asked to specify the group name.
Line: Set the line color.
Load: Set the load color.
Node: Set the node color.
Point: Set the point color.
Solid: Set the solid color.
Surface: Set the surface color.

________________________________________

Defaults

Specify the default values used by NAVGRAPH during its execution.

Angle-units: Select the default angle units used during execution of the program. The two options are degrees or radians.

________________________________________

Display-options

Select the display option parameters effecting the appearance of the graphics output.

Auto-center: If AUTO-CENTER is on, then the graphics output will always be centered in the middle of the screen.
Auto-draw: If AUTO-DRAW is on, then the graphics screen will be automatically updated every time a command that changes its appearance is executed. Some commands that would cause this automatic update are the VIEW-OPTIONS ROTATE, TRANSLATE, and SCALE.
Auto-erase: If AUTO-ERASE is on, then the graphics screen is erased before every AUTO-DRAW or DRAW command.
Auto-menu: If AUTO-MENU is on, then the menu is displayed whenever an incomplete command is entered even if the MENU command was previously used to disable menu display.
Backface-removal: If BACKFACE-REMOVAL is on, then all polygons facing away from the user are not displayed during a DRAW command. You must specify the element order that defines an outward pointing normal, i.e. clockwise or counter-clockwise.
Current: Enter the previously stored display options. These will replace those currently defined.
Delete: Enter the previously stored display options that you wish to delete.
Directory: List the names of the previously stored display options.
Entity: Specify the NAVGRAPH entities that will be displayed with a DRAW command.
Feature-angle: Enable or disable the display of the boundaries between adjacent elements when the normals to the elements intersect at an angle less than the one you specify.
Free-edge-check: Enable or disable the display only those element boundaries that are not shared with another element. This is very useful in locating holes in your mesh.
Hidden: Enable or disable the removal of hidden surfaces. This command is only available for element data in the Post Results module.
Label: Specify the NAVGRAPH entities that will be labeled with a DRAW command.
Minimum-arc: Set the minimum number of line segment used to describe an arc.
Mode: Set the display mode.
Normals-check: Enable or disable checking for consistent normal direction.
Resolution: Set the resolution use in the hidden surface removal.
Shrink: Set the shrink factor for the elements. The distance from element centroid to each node is reduced by the shrink factor. The elements appear separated.
Status: Report the current status of the various display options.
Store: Store the current display options for later retrieval with the CURRENT command.
Title: Set the title information for the current problem. The title may span three 80 character lines.
Triad: Enable or disable the display of the coordinate triad. The triad reflects the orientation of the global axis system but is not positioned at origin.

________________________________________

Draw

Draw the geometry or mesh using the current display options.

________________________________________

Exit

Exit NAVGRAPH. You will be asked if you want to save the problem or not. If you do, you will be asked for the file name.

________________________________________

Group

Group entities together for easier manipulation. Groups may be thought of as set of constraints, elements, lines, loads, etc. Groups may also contain other groups.

Add: Add NAVGRAPH entities to the current group.
Current: Select the group that will be the current group.
Delete: Delete a group from the data base.
Directory: List the groups in the data base.
New: Start a new group. If the last group was not saved with the SAVE command, it is automatically renamed OLD. The new group is called NEW until it is saved.
Rename: Rename a group. If you forgot to save a group before issuing a NEW command, you can recover by renaming the OLD group to some other name before issuing a second NEW command.
Remove: Remove NAVGRAPH entities from the current group.
Save: Save the current group in the data base. You must specify the name of the group at this time.

________________________________________

Hardcopy

Generate a hardcopy of the current screen display.

Defaults: Set the defaults for the hardcopy command.
File: Specify the file name for the hardcopy output.
Output-queue: Specify the queue for the hardcopy output.

________________________________________

Help

Help is a global command accessible from any menu or sub- menu.

________________________________________

Recall

Recall and executed a previously captured journal file.

________________________________________

Reset

Restore NAVGRAPH to the state it was before any commands, other than RECALL, were entered.

________________________________________

Time

Report the accumulated terminal and cpu time for the current NAVGRAPH session.

________________________________________

View-options

Select the view option parameters effecting the orientation of object for graphics output.

Center: Set the look-at and look-from positions to center the object in the screen.
Current: Select the view options previously stored to be the current ones.
Delete: Delete the view option specified from the data base.
Directory: List the view options previously saved in the data base.
Distance: Set the distance from the eye of the observer to the object origin in model units.
Fill: Fill the screen with the model. This command is similar to the CENTER command but changes the also changes the distance from the origin to the observer to "fill" the screen.
Look: Select the look-at and look-from position. The look-at position is translated to the center of the screen, i.e. becomes the origin, while the object is rotated and translated to place the look-from position along a line extending perpendicularly from the screen to your eye.
Magnify: Magnify the screen image my the factor given. This is similar to using the DISTANCE command to change the distance from your eye to the origin.
Pan: Move side to side or up and down over the object.
Restore: Restore the transformation matrix to the identity matrix. This returns the global model coordinate axis to the center of the screen.
Rotate: Rotate the object about one of the coordinate axes.
Status: Display the status of the current view options.
Store: Store the current view options in the data base.
Zoom: Select a subregion of the screen for display. After the window is selected, the transformations are calculated that will fill the screen with this region.
Z-clip: Set the near and far clipping planes. All graphical entities in-front-of or behind the planes will not be displayed with a DRAW command.
