HVAC

Select HVAC from the Drawing Type drop-down list to display the HVAC version of the MTO General Defaults window.

The character that is used to separate the parameter values from one another, must be set. Any character for this separator including a blank can be used, input a value in the Field Separator field.

To display the Key characters, select the Display Key Characters check box.

The Parameter KEY character is used to relate the Parameter to the HVAC Standard Drawings for each component. Refer to HVAC Standard Drawings for further information.

The Parameter symbol is a character that indicates the type of parameter such as diameter ø, radius r and degrees °.

To display a symbol alongside each parameter if set, select the Display Symbol check box.

To replace the KEY character with any existing SYMBOL select the Replace check box.

Both the KEY and SYMBOL characters are stored in data sets in the Catalogue under the section /CADCHVACMTO, which is loaded during the Project Set Up process via the supplied data file Hvac_Paragon.dat. Refer to Project Set-up for further information.

Once the catalogue has been modified, a data set (DTSE) for each component that owns a data element (DATA) for each parameter can be found. The DATA element holds the KEY and SYMBOL characters in the attributes DKEY and DTIT respectively. These characters can be modified as required.
