How to Create new Drawing Attribute Combining Multiple other Drawing Attributes and Map with New Text Node

To create new drawing attribute combining multiple other drawing attributes and map it with new text node in generated Isometrics of OpenPlant Isometrics Manager.

Background

In OpenPlant Isometrics Manager, user requirement is to create new Text Node, which could be mapped with multiple drawing attributes. For example, user wants to create LINE_ID_TAG text node, which could show NOMINAL_DIAMETER, SERVICE, LINENUMBER and SPECIFICATION.

Steps to Accomplish

1. Open node2da.txt and textnodes.txt files from your Isometrics style's config folder.
   
   For OpenPlant Modeler:
   C:\ProgramData\Bentley\OpenPlantModeler V8i\WorkSpace\Projects\[...]\DataSet\Isometrics\Styles\[...]\Config
   
   For AutoPLANT Modeler:
   C:\ProgramData\Bentley\Plant V8i\Bentley Plant V8i Projects\[...]\Config\OpenPlant\Isometrics\styles\[...]\config
   
   
   
   
2. We need to define LINE_ID_TAG variable with multiple attributes in textnodes.txt file and for this purpose we will use existing drawing attributes which are already mapped in node2da.txt file.
   
   
   
   
3. At the beginning of textnode.txt file are information how drawing attribute definition can be created. With the help of this information I have combined existing attributes in to one.
   
   <DA name> = <expression>
   
   LINE_ID_TAG = LINE_ID: $(SIZE1)-$(SERVICE)-$(LINENUMBER)-$(SPECMAIN)
   
   
   
   
4. Now map this new drawing attribute with new textnode in node2da.txt file
   
   70, LINE_ID_TAG
   
   
   
   
5. Open same projects styles isoseed.dgn file and place this new text node in required position
   
   
   
   
6. Save all changes, close isoseed, generate Isometrics and verify the results.
