Configuring Template Doors and Windows for Use with the Hole Management System

The GPART mechanism allows doors and windows to be defined as SFITs in the catalogue or as template (TMPL) elements in the Design database. From the point of view of the room designer, using templates or SFIT or a combination of elements is purely down to convenience as both should work equally well.

Template (TMPL) penetrations require specific elements to be created within the template hierarchy to represent the holes that are required when a template item penetrates a panel or CTWALL. These penetrations are represented by extrusion elements (EXTR or NXTR) stored in the template hierarchy. These elements will each contain a loop element (LOOP) and vertices (VERT elements) to define the shape of the hole required. These are called penetration profiles.

Like the catalogue items, different shaped penetrations may be defined for penetrating CTWALLs or PANELS, but the identification mechanism is slightly different. For templates, a Port Set (PORS) element is created below the template with a port (PORI) element below. The PORI element has a reference attribute tarf which is used to reference the LOOP element to be used as a penetration.

To differentiate between a hole for Room Design and a hole for hull or panels, the purpose OPGE and HPGE are used in the same way as catalogue components but this time applied to the Port set elements.
