Sets the definitions for the Drawing Number Calculator.

The Isometric Drawing has a database name, which cannot include spaces, as a result the attribute NAME of the DRWG element cannot hold the Drawing Number, if it contains spaces, use the DRWG attribute DRWGNUMBER instead.

The Drawing Number itself is calculated by executing a PML Function, which can be modified.

The Drawing Number is calculated using the PML Function !!isoDrwgNo ().

The PML Function uses the defaults file %AVEVA_DESIGN_DFLTS%\DRA-ISO-DRWGNO for the default drawing number components and a number in the following format:

Prefix + Separator + Element Name + Separator + Index No+ Separator + Suffix

Element Name

The name of the HVAC or CWAY being detailed

Index Number

Extracted using a Name Sequence (NSEQ) database to obtain the next number. Refer to Sequence Number Generator for further information.

The calculated value is stored in the DRWG attribute DRWGNUMBER. For example:

Refer to User PML Functions for further information on PML Functions.

The settings for this window are stored in the defaults file DRA-ISO-DRWGNO.

To use the Name Sequence Database (NSEQ) method for extracting the next index number, select the Use a Name Sequence Database check box. Refer to Name Sequence Database for further information.

From the Drawing Type drop-down menu, select HVAC or Electrical.

To set the word to be used as the prefix, input the required word in the Prefix field.

To set the word to be used as the suffix, input the required word in the Suffix field.

To set the character(s) to be used as the separator characters, input the required characters in the separators characters field.

Note: If spaces are required between fields use the word space.

The Starting Index Number for the chosen Drawing Type must be input, use numbers with leading zeros, for example, 0001. Input the required number in the Starting Index Number field.
