Dear @Amundsen Elena Victoria

You can import custom engineering stencils into Visio for the web with Visio Plan 2, but this does not provide the full desktop P&ID functionality. The basic Visio included with Microsoft 365 and Visio Plan 1 do not include custom stencil import.

There are two options:

For drawing with piping and instrumentation symbols in your browser: With Plan 2, you can import compatible .vssx stencil files containing those shapes. A stencil is a collection of symbols, rather than a complete engineering template.
For the full P&ID workflow: I recommend the Visio desktop application included with Plan 2. Microsoft documents the Piping and Instrumentation Diagram template there, including smart pipelines, component tagging and equipment reports. Importing symbols into the browser does not add these desktop features. Please refer to this document: Create a P&ID or PFD

Could you confirm your Visio license and whether the files you want to import are .vssx stencils or .vstx templates? This will help me suggest the correct next steps.

Hello, I have web based Visio as a part of MS Office 365 (plan 1). I will reach our IT department and check is we can upgrade Visio to Plan 2. Most likely I will ask to install Visio Desktop as it has more support of the Engineering templates. Thank you so much for details! Elena

No. The web-based Visio in Microsoft 365 does not support engineering diagrams such as P&ID for viewing or editing.

For engineering templates, including basic electrical and Piping and Instrumentation Diagrams (P&ID), support is listed under Visio Plan 2. The context also states that certain diagram types in Plan 2 are available only in the Visio desktop app, not in Visio for the web.

If the goal is to work with piping, instrumentation, or P&ID templates, the supported option is Visio Plan 2, and some of those engineering diagram capabilities require the desktop app rather than the web app.
