Setting Owning and Attached Parameters

Owning and attached parameters (OPAR and APAR, respectively) are real-array attributes of Joints. They are set in the Catalogue, and allow the Joint to derive data (usually dimensions) from its owning or attached Section(s) when it is introduced into the design. See the Catalogues and Specifications User Guide for further information about the setting of these arrays.

As with the design parameters described in Setting Design Parameters, an OPAR or APAR is referenced in the design by means of its numbered position in the corresponding array.
