Create symbols compatible with ISO 15926 schema

To preserve their geometrical shape, you must create project symbols using basic geometrical definitions for drawings exported to ISO 15926 XML schema.

Note:

Do not use other methods in Visio to import or create shape symbols as they might not preserve their integrity when exported to ISO 15926 XML.

Do not use Visio entities for symbol definitions to ensure compatibility with ISO 15926 schema.

Splines are not supported for ISO 15926 export.

Cloud Revision entities are not supported by Microsoft Visio. When the generated XML is imported into an application, the imported drawing produces a distorted image.

Any created shapes must have connection points and defined entities to ensure they can be exported to a valid XML file and are compatible with ISO 15926 schema export.

Signal lines for ISO 15926 export are not supported. The signal lines export as polylines.

11. Select Edit Connections Points to display the Edit Connections Points window.

    

12. Right click on the points that require connection.

13. Select the Connection type, Connection number and Connection Point type. Repeat the process for the next connection.

    

14. To define symbol as a directional component, select the Directional component checkbox. To set its GTYPE as an instrument, select the Classify as Instrument (GTYPE=INST) checkbox.

    

15. Select Next to display the Import Shape Wizard step 2 of 5: Destination Stencil.

    

16. Select the required class in the Select Class window. Select Next to display the Import Shape Wizard step 3 of 5: Annotation Style Settings window.

    

    

17. Select Next to display the Import Shape Wizard step 4 of 5: Attribute Presentation Settings window.

18. Select your options in Attribute Presentation Settings or select Use default attribute presentation Settings.

    

19. Select Next to display the Import Shape Wizard step 5 of 5: Default Catalogue Search Filter window.

20. Select Finish.

    

21. Select Yes to save your work.

    

22. The shape is saved in your chosen stencil.

    

23. Drag the new stencil to a drawing with drag and drop.
