Description:

The physical shapes of equipment, structural and civil items in the Ship are built up by creating, dimensioning and assembling basic geometric elements. These commands directly set the attributes of basic modelling primitives which give them their precise dimensions. The following primitive shapes are available:

Box

Cone

Dish

Cylinder

Slope-bottomed Cylinder

Snout

Circular

TorusRectangular Torus

Pyramid

Holes may be plunged through ‘solid’ primitives using a corresponding set of negative primitives. The examples given in this subsection refer to the Box and Cylinder; a complete description of all primitive elements and their attributes can be found in Data Model Reference Manual.

Examples:

XLEN 1000

(At a Box)

The xlength dimension of the box becomes 1000

DIA 3 FT

(At a Cylinder)

The diameter of the cylinder becomes 3 feet

Command Syntax:

Refer to the Data Model Reference Manual.
