The computer can provide external stimuli, through goggles or screens, which the operator can expect to experience in practice. These simulators can be produced to various levels of realism, depending upon the need. They do not reduce the master’s or captain’s responsibility.Ĭomputer-based simulators can assist in training navigators, machinery controllers and so on. It is emphasised that they are only used in an advisory capacity in these roles. In warships they can assist the captain when under enemy attack by suggesting the optimum actions to take in defending the ship. Computer-based decision-aiding systems can help the master by providing guidance on the loading sequences to eliminate the possibility of jeopardising the stability or strength.
DEFINE CAD CODE
Listings of equipment and fittings, with code numbers, will ensure that any replacements and spares will meet the form, fit and function requirements.
DEFINE CAD SOFTWARE
Hydrostatic, hold and tank capacity, stability and strength data can be fed into the ship’s own software systems to assist the captain in loading and operating the ship safely.

DEFINE CAD MANUAL
Standardise pipe-support structures using an approved manual Standardise weld detail design using approved procedures (12) Hatching: User can edit both hatch boundaries and hatch patternsĬomputer-aided design (CAD) systems were in operation in the design offices and were of help when introducing the following steps to: (11) Filleting: Connects two objects with a smoothly fitted arc of a specified radius. (10) Chamfering: Connects two nonparallel objects by extending or trimming them to intersect or join with a beveled line. (9) Offsetting: Creates a new object that is similar to a selected object at a specified distance. (8) Scaling: Enlarges or reduces the cell by a specified factor along x-, y-, and z-axes. (7) Trim: Removes any part of the cell extending beyond a defined point, line, or plane. (6) Removal: Erases the cell from the display, but maintains it in the design data file. (5) Deletion: Removes the cell from the display and the design data file. (4) Mirroring: Displays a mirror image of the cell about a plane. Rotation: Rotates a cell a given angle about an axis.

(2) Duplication: Allows a cell to appear at a second location without deleting the original location. Most CAD systems offer all of the following editing functions, as well as others that might be specific to a program being used: (1) Movement: Allows a cell to be moved to another location on the display screen. Transformation in general refers to the movement or other manipulation of graphical data. Most of the editing features offered in CAD is transformations performed using algebraic matrix manipulations. Common editing features are performed on cells of single or conglomerate geometric shape elements. Dominick Rosato, Donald Rosato, in Plastics Engineered Product Design, 2003 CAD editingĬAD systems offer the engineer powerful editing features that reduce the design time by avoiding all the manual redrawing that was traditionally required.
