HVAC Design Parameters

HVAC parameters specify how HVAC components should be projected in a view.

HVAC parameters can be configured in the Standard Definition dialog box which appears when you select Me > Preferences > Standards. After selecting the generativeparameters category, you can then select the XML file you want to configure. Piping/Tubing Design parameters are located in the HVAC Design node of this XML file.

Note: For more information, see HVAC Design Administration's Guide: Integration with Generative Drafting.

This page discusses:

GR_0 / GR_1 / GR_2

Note: Each GR_n node is dedicated to configuring different graphical representation options for HVAC components based on their nominal sizes. For example, the GR_0 nominal size range can be set from 0.5in to 2in, GR_1 from 2.5in to 10in and GR_2 from 12in to 24in. Take care to ensure that the ranges do not overlap each other.
Parameter Value Description
Min_NominalSize String Specifies the minimum nominal size that a piping part, pipe or insulation should have in order to be projected in a view, using the graphical representation options defined in this GR_n node. Leaving the value blank means that all values under the value specified for Max_NominalSize are possible.

By default, the value is 0in.
Max_NominalSize String Specifies the maximum nominal size that a piping part, pipe or insulation should have in order to be projected in a view, using the graphical representation options defined in this GR_n node.
