The End Spec<value>_<value> schema

Mechanical discipline end conditions are modified in the End Spec schema properties, often termed as Connection Parameters. The three types of properties are arranged in different combinations depending upon the geometry of the active component.

The schema name also displays the number of end connections and shape types in the parenthesis as "(# of end Connections: Shape1 | Shape2 | Shape 3)", where shape type 1 is for rectangular, 2 for round and 3 for oval shapes. For example, the End Spec schema for Rectangular to Round Transition displays End Spec 2_12 (2 Connections: Rect | Round) implies the fitting has 2 connections, the first being a rectangular end and the second a round end.

Property Name	Description
D1 Ø D2 Ø D3 Ø D4 Ø D5 Ø D6 Ø D7 Ø	`<Positive numeric value>` Sets the diameter of the main branches for round shaped components. D2 Ø also sets port diameter of the fitting at End2. Note: For several of fittings, e.g. Alarm Check Valve, Floor Drains, Convectors -sill and trench, etc., both D1 Ø and D2 Ø maintain same value, where D2 Ø is controlled by D1 Ø.
D1 D2 D3 D4 D5 D6 D7	`<Positive numeric value>` Sets the depth of the main branches for rectangular and oval shaped components. D1 also sets grille depth at End1. D2 also sets port depth at End2.
W1 W2 W3 W4 W5 W6 W7	`<Positive numeric value>` Sets the width of the main branches for rectangular and oval shaped components. W1 also sets grille width at End1. w2 also sets port width at End2.
