Description
The physical shapes of equipment, structural and civil items in the Plant 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.
Example |
|
|---|---|
|
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 |
