Primitives

Equipment

Equipment : Model Equipment : Primitives

Equipment elements consist of a collection of primitives, positioned in the 3D graphical view as a graphical representation of the piece of equipment. The primitives are created using parameters in the graphical view. The initial method of creation is the default although other methods are available for selection.

Note:

The primitives should be built such that their lengths are aligned with the default axis system and not built in such a way that they need to be rotated from the default axis system.

For example, the simple storage vessel shown below can be constructed from a cylinder for the main body, two dishes for the ends, two boxes for the support legs and a nozzle for the piping connection.
