Design Template Hierarchy

Design Template (TMPL) elements are usually stored in a separate Design DB under an administrative Template World (TPWL) , which is itself divided into administrative Template Areas (TMAR) .

Each TMPL is initially created as a copy of an existing set of design elements which have been created in a part of the usual hierarchy below a SITE. The TMPL may then be modified by the addition of positive and/or negative primitives, negative extrusions, etc. For example, a very simple template, consisting of a positive box and a negative box, could be created thus:

When this template is instanced in a design model, say under a panel fitting, its constituent elements are copied back and all parameterization rules are executed so that the attributes of the copy are set to suit the local Model requirements, thus:

All attributes of the copy are locked to prevent unintentional changes.
