Using a Design Template Item in a Design

To create an instance of a ‘source’ design template in a design model, first create a template below the owning design element and then copy into this the details of the source template (which must be in a template world) from which it is to derive its data. The commands (at the design element which is to own the instance) are:

NEW TMPL
COPY REXEcute template_identifier

where template_identifier is the name of the source template. The effects are as follows:

• All elements below the original design template are copied below the new TMPL.

• All template rules are copied and re‑executed, thus setting the attributes of the new TMPL members to suit the design data.

• The Origin Reference (ORRF) attributes for the new TMPL elements are set to point to their equivalents in the source template.

• All elements below the new TMPL are locked to prevent unintentional changes to any of their attributes.

To change an attribute explicitly, thereby causing it to differ from the design as specified in the source template, the user must first unset the ORRF references which point back to the source and unlock the members. To do so, use the command

UNTIE template_instance

where template_instance is the name of the copy TMPL in the design model hierarchy.
