Modelling Detail Levels

LEVEL

Description

This command sets the attribute, common to all primitive elements, that controls modelling detail. The command specifies a range of modelling ‘levels’ which determine the permanent visibility characteristics of the element in Model. The attribute allows Plant items to be assembled from overlaid primitives representing varying levels of detail. In this way, several graphical versions of the same object can be available for different purposes. For example, it may be decided to represent an I-section beam as a single box for simple space-modelling in Model, while using its full cross-section for 2D drawing data in Draw.

The LEVEL attribute is specified as two numbers, representing the inclusive range in which that item will be drawn. In Model, only primitives of visible items whose LEVEL range includes the LEVEL setting specified by the REPRESENTATION command will be drawn (refer to Display for further information).

LEVEL ranges for Nozzles and piping are specified in the Catalog. A company will usually establish rigid standards for the use of LEVELs which are defined permanently in the Catalog and therefore must be complied with during Equipment and Civils modelling.
