CASD

Starting CASD

CASD can be started by clicking the CASD icon in the top left corner of the RunManager window.

Alternatively, on Linux the following command can be written:

>run casd

Main window

The main CASD window is annotated in the figure below. The main window is divided into the following parts:

• The menu bar

• The tool bar

• The command input field

• The geometry window

• The scenario menu

• The status field

• The status bar

The geometry window and scenario menu are dockable (top right corner) and can be moved (dragging top border) and resized (drag from the sides).

Menu bar

The menu bar contains the following menus:

• File

• Geometry

• Grid

• Porosities

• View

• Options

• Macro

• Help

• Python

Tool Bar

The tool bar contains the following parts:

• Main section - provides shortcuts to several of the commands on the menu bar (listed from left to right following the icons in the image above):

  • New

  • Open

  • Save

  • Save as

  • Import

  • Undo

  • Redo

  • Calculate porosities

  • Verify porosities

• Utilities section:

  • Plan drawings - add plan drawings as a design guide

  • Load filter - load selected parts of a geometry

  • Edit clip plane

  • Toggle clip plane

• Graphics section - controls various features of the geometry window

  • View splitting

  • Rectangle zoom

  • Spinning (toggle on/off)

  • Highlighting option, from filled only (0) to various degrees of contour highlighting (1-5)

• Snap point section - snap points are active points on objects and primitives:

  • Snap to corner

  • Snap to edge

  • Snap to face

• Save layout

  • Creates a layout based on the current arrangement of the CASD main window components

Command input field

The command input field represents an alternative interface between the user and CASD, in addition to the regular menus on the menu bar. The control input field contains a scrollable command history list, and a current command context indicator (left side). To control the command history list from the keyboard use:

• UP: retrieves the previous line from the command history list

• DOWN: retrieves the next line from the command history list

• RETURN: processes the content of the command input field

Hence, you can choose whether to use a menu option on the menu bar, for example: File →Exit →Yes (to exit and save) or to execute, after typing or retrieving, the following command in the command input field:

file exit yes yes

Examples of command line inputs are provided in section '3.1.5.3 The command input field’ of the FLACS manual.

Geometry window

The geometry window in the main window displays the geometry, the computational grid and scenario parameters. In addition to the options on the View menu, there are several ways of manipulating the view:

• Rotation: left-click+drag

• Panning: CTRL+left-click

• Zoom: rotate mouse wheel

• Rectangle zoom: right-click and select

• Rectangular Zoom

• Splitting and closing views: right-click+SELECT

Status field

The status field in the main window contains information concerning the:

• Project

• Geometry

• Grid

• Units

Geometry window icons

Each geometry window has an icon bar underneath. The geometry window icon bar has following the following functions:

• Switch between walk viewer and fly viewer

• Selection mode on

• View mode on

• Store camera position

• Re-store camera position

• Seek to picked point

• View all

• Switch between parallel and perspective projection

• Turn axis on/off

• View along X axis

• View along Y axis

• View along Z axis

Cursor coordinate field

A cursor coordinate field is located to the lower left of the geometry window. In ‘Select mode’ this field shows the position of the mouse cursor in the geometry. In ‘View mode’ this field shows the position of the current snap point, which is set by performing a CTRL+left-click in the geometry window.

A right-click in the cursor coordinate field opens a context menu with options to copy the coordinate value to the clipboard, and to change the font in the field. Changes to the font, e.g. size or typeface, are saved in the user settings.

Status bar

The status bar in the main window displays information concerning:

• The current model being visualised (FLACS  or visualisation model)

• If any load filter is enabled

• The current unit in use
