Setting MODEL Parameters

DESPARAMETERS

Description

Model parameters (DESP) are array-type attributes of any element which has a Specification Reference (Sections, Joints, Fittings etc.), each of which may store up to 100 real values. They may be used to transfer design data to a corresponding Catalog component, or to a component’s attached or owning design element.

As an example, this enables one or more dimensions of a Joint to be derived from the dimensions of the Section(s) to which it is attached, rather than from preset dimensions defined for it in the Catalog.

A DESP is referenced in the design by its numbered position in the array. Its value must be set before the corresponding component is selected from the Catalog, so that the required setting is available within the design.

Parameters are either numeric values or WORDs (4 to 6 upper case alphabetic characters) which are internally stored as integer values.

Note:
In the last example, a range of three design parameters, needed to hold the co-ordinates of the defined point, was set automatically, starting with the specified third parameter.

Command Syntax

Setting parameters in default order in the array, starting at parameter number 1:

                      .--------------<------------.
