|This task explains the turn design rule for HVAC Design.|
|The turn design rule
included with this application is used by the routing a run function. See
Routing a Run for more information. HVAC
ducts cannot be bent, therefore the HVAC turn rule does not determine a
bend radius as in other applications. Instead, for HVAC, the turn rule
places a part on a bend and the rules table determines what kind of part to
place based on the type of run.
This is a specification-related design rule and the associated table is located in the directory ...\intel_a\Startup\EquipmentAndSystems\Hvac\Specification.
|1.||The image below shows the turn
rule design table.
The "shape" and "size" columns in the table contain the input values. Only one nominal size value is input - the columns MinSize and MaxSize constitute a range, inclusive of the values in the two columns. Thus, an input of 1 inch is a match for this table, .5 inches is not.
The output is in the TurnPartType column, which determines the kind of part based on the run shape.
For a Round shape the diameter of the run is input; for a rectangular shape the greater of width or height is input; for a flat oval shape the greater of width or height is input.
